New materials for quantum technology, how ultrasound can help detect breast cancer

Physics World Weekly Podcast

In this episode of the Physics World Weekly podcast, we explore how computational physics is being used to develop new quantum materials; and we look at how ultrasound can help detect breast cancer.

Our first guest is Bhaskaran Muralidharan, who leads the Computational Nanoelectronics & Quantum Transport Group at the Indian Institute of Technology Bombay. In a conversation with Physics World’s Hamish Johnston, he explains how computational physics is being used to develop new materials and devices for quantum science and technology. He also shares his personal perspective on quantum physics in this International Year of Quantum Science and Technology.

Our second guest is Daniel Sarno of the UK’s National Physical Laboratory, who is an expert in the medical uses of ultrasound. In a conversation with Physics World’s Tami Freeman, Sarno explains why conventional mammography can struggle to detect cancer in patients with higher density breast tissue. This is a particular problem because women with such tissue are at higher risk of developing the disease. To address this problem, Sarno and colleagues have developed a ultrasound technique for measuring tissue density and are commercializing it via a company called sona.

00:00:09,359 --> 00:00:12,320
Hello, and welcome to the Physics World Weekly

2
00:00:12,320 --> 00:00:14,259
podcast. I'm Hamish Johnston.

3
00:00:15,074 --> 00:00:17,495
Coming up in this episode, we meet Daniel

4
00:00:17,554 --> 00:00:18,054
Sarno,

5
00:00:18,434 --> 00:00:19,495
who is a cofounder

6
00:00:19,954 --> 00:00:22,774
and chief technology officer of Sona.

7
00:00:23,635 --> 00:00:24,774
Based at The UK's

8
00:00:25,154 --> 00:00:26,774
National Physical Laboratory,

9
00:00:27,460 --> 00:00:30,919
Sona is developing a new method for determining

10
00:00:31,140 --> 00:00:32,600
breast tissue density

11
00:00:33,219 --> 00:00:34,280
using ultrasound

12
00:00:34,820 --> 00:00:37,719
rather than conventional x-ray based mammography.

13
00:00:38,739 --> 00:00:39,799
Sarno explains

14
00:00:40,179 --> 00:00:41,799
how this can help improve

15
00:00:42,344 --> 00:00:43,484
the early detection

16
00:00:43,864 --> 00:00:45,085
of breast cancer.

17
00:00:45,864 --> 00:00:47,884
But first, I'm in conversation

18
00:00:48,504 --> 00:00:49,484
with Bhaskaran

19
00:00:50,104 --> 00:00:51,405
Muraleed Haran,

20
00:00:51,945 --> 00:00:55,004
who is at the Indian Institute of Technology,

21
00:00:55,545 --> 00:00:56,045
Bombay.

22
00:00:57,090 --> 00:00:59,909
An engineer by training, he has a keen

23
00:01:00,049 --> 00:01:03,890
interest in using computational physics to develop new

24
00:01:03,890 --> 00:01:05,270
materials and devices

25
00:01:05,650 --> 00:01:07,670
for quantum science and technology.

26
00:01:08,609 --> 00:01:09,989
I began the interview

27
00:01:10,444 --> 00:01:13,504
by asking about how computational science

28
00:01:13,805 --> 00:01:15,344
is being used to create

29
00:01:15,805 --> 00:01:17,185
new quantum materials.

30
00:01:26,409 --> 00:01:26,909
So

31
00:01:27,290 --> 00:01:30,090
in order to so the next generation of

32
00:01:30,090 --> 00:01:31,150
quantum technologies

33
00:01:32,170 --> 00:01:32,990
will feature

34
00:01:33,689 --> 00:01:36,170
what is called quantum hardware. And the quantum

35
00:01:36,170 --> 00:01:38,350
hardware is obviously devices.

36
00:01:39,314 --> 00:01:41,414
And just like you have the

37
00:01:42,034 --> 00:01:44,994
complementary MOS or the CMOS being the building

38
00:01:44,994 --> 00:01:46,774
block of the digital technology,

39
00:01:47,474 --> 00:01:50,515
you will have building blocks based on quantum

40
00:01:50,515 --> 00:01:52,054
devices for the next

41
00:01:52,409 --> 00:01:54,829
generation or the upcoming quantum technologies.

42
00:01:55,450 --> 00:01:59,469
For example, the, superconducting qubit, that's a device.

43
00:01:59,609 --> 00:02:00,109
So

44
00:02:00,810 --> 00:02:02,670
just like in the CMOS era,

45
00:02:03,450 --> 00:02:03,950
the

46
00:02:04,805 --> 00:02:07,444
the industry relied on device modeling as an

47
00:02:07,444 --> 00:02:10,564
important aspect of, you know, giving feedback to

48
00:02:10,564 --> 00:02:11,064
experiments.

49
00:02:11,444 --> 00:02:13,544
So there's whole there's this whole thing about

50
00:02:13,844 --> 00:02:16,805
a feedback between theory and experiment and and

51
00:02:16,805 --> 00:02:19,205
as to achieve a synergy between theory and

52
00:02:19,205 --> 00:02:19,705
experiment.

53
00:02:20,290 --> 00:02:21,830
So that first experiment

54
00:02:22,210 --> 00:02:23,990
is understood via theory

55
00:02:24,370 --> 00:02:27,010
and then the theory can probably predict something

56
00:02:27,010 --> 00:02:29,490
new. And the experiment can go toward that

57
00:02:29,490 --> 00:02:31,430
step and back and forth and,

58
00:02:31,730 --> 00:02:33,349
you know, that's how things develop.

59
00:02:34,004 --> 00:02:36,485
Another thing is theory is also useful in

60
00:02:36,485 --> 00:02:36,985
giving

61
00:02:37,365 --> 00:02:38,344
inputs about

62
00:02:38,805 --> 00:02:41,444
possibly new materials that can achieve the same

63
00:02:41,444 --> 00:02:41,944
functionality.

64
00:02:42,724 --> 00:02:43,865
One great example

65
00:02:44,485 --> 00:02:45,705
is just before

66
00:02:46,200 --> 00:02:48,460
we are in what is called the Beyond

67
00:02:48,520 --> 00:02:52,120
Moore era, where devices are shrinking toward the

68
00:02:52,120 --> 00:02:52,620
limits

69
00:02:53,319 --> 00:02:55,659
and people are looking at alternate technologies.

70
00:02:56,520 --> 00:02:57,500
One of the technologies

71
00:02:57,800 --> 00:02:59,639
just before all this quantum,

72
00:03:00,605 --> 00:03:02,385
revolution started was Spintronics.

73
00:03:03,165 --> 00:03:05,025
Spintronics is the technology

74
00:03:05,405 --> 00:03:06,064
or the

75
00:03:06,444 --> 00:03:09,185
or what's called the paradigm which tries to

76
00:03:09,564 --> 00:03:11,824
use spins or the electron spins

77
00:03:12,444 --> 00:03:13,985
as a medium of information.

78
00:03:14,509 --> 00:03:16,590
Just like you have the charge, which is

79
00:03:16,590 --> 00:03:18,609
basically the charge of the electron,

80
00:03:19,069 --> 00:03:21,229
you also each electron comes with a spin.

81
00:03:21,229 --> 00:03:22,909
And in high school, you would have studied

82
00:03:22,909 --> 00:03:25,150
up spin and down spin. That can be

83
00:03:25,150 --> 00:03:26,209
units of information.

84
00:03:26,895 --> 00:03:28,514
So one of the things computation

85
00:03:28,814 --> 00:03:31,375
did is that they predicted a new material

86
00:03:31,375 --> 00:03:32,754
called magnesium oxide,

87
00:03:33,294 --> 00:03:36,835
which can produce a better spintronic device. And

88
00:03:37,135 --> 00:03:40,435
lo and behold, that tech the magnesium oxide

89
00:03:40,495 --> 00:03:40,995
based,

90
00:03:41,769 --> 00:03:45,549
Spintronic devices are getting close to, you know,

91
00:03:45,930 --> 00:03:47,930
being in the market or something like that.

92
00:03:47,930 --> 00:03:50,590
This is an example where theory can predict

93
00:03:50,650 --> 00:03:51,629
a new functionality

94
00:03:52,330 --> 00:03:54,830
and eventually lead to new developments.

95
00:03:55,575 --> 00:03:57,594
The same goes with probably

96
00:03:58,694 --> 00:04:01,275
several nice ideas can come from theory.

97
00:04:01,735 --> 00:04:02,715
And computational

98
00:04:04,215 --> 00:04:05,355
is the computational

99
00:04:05,814 --> 00:04:08,534
modeling is the next step. Theory is more

100
00:04:08,534 --> 00:04:10,819
like at the level where you can come

101
00:04:10,819 --> 00:04:13,159
up with neat ideas from physics.

102
00:04:13,699 --> 00:04:16,740
Then comes the actual computational modeling where you

103
00:04:16,740 --> 00:04:20,600
try to simulate possibly the actual device situation.

104
00:04:21,300 --> 00:04:23,295
And that is more hands on towards

105
00:04:23,855 --> 00:04:27,555
talking to experimentalists or talking towards technology, etcetera.

106
00:04:28,335 --> 00:04:30,375
So another example is back in the ninety's

107
00:04:30,574 --> 00:04:32,895
sorry, back in the early two thousand's, people

108
00:04:32,895 --> 00:04:35,694
were trying out carbon nanotube transistors as a

109
00:04:35,694 --> 00:04:38,319
possible next generation. And that's when a lot

110
00:04:38,319 --> 00:04:39,740
of theorists were working

111
00:04:40,199 --> 00:04:42,860
at the level of understanding how carbon nanotubes

112
00:04:42,920 --> 00:04:45,960
can behave like transistors, etc. Today, there's a

113
00:04:45,960 --> 00:04:48,279
lot of computational theory which working on two

114
00:04:48,279 --> 00:04:48,939
d materials.

115
00:04:49,800 --> 00:04:50,620
And especially

116
00:04:51,080 --> 00:04:51,580
toward

117
00:04:52,324 --> 00:04:53,944
transistor technologies, etcetera,

118
00:04:54,245 --> 00:04:56,905
on molybdenum disulfide and various other materials.

119
00:04:57,525 --> 00:04:59,605
The same way I could say that theory

120
00:04:59,605 --> 00:05:00,745
and modeling helps

121
00:05:01,125 --> 00:05:03,525
in many ways. One is, of course, there's

122
00:05:03,525 --> 00:05:05,705
a lot of work on superconducting qubits.

123
00:05:06,199 --> 00:05:07,740
And then from the superconducting

124
00:05:08,040 --> 00:05:09,899
qubits, you need to achieve

125
00:05:10,279 --> 00:05:10,779
communications

126
00:05:11,160 --> 00:05:12,300
between these qubits.

127
00:05:12,600 --> 00:05:14,839
So there's a lot of theory and modeling

128
00:05:14,839 --> 00:05:17,399
at that level where you can understand and

129
00:05:17,399 --> 00:05:18,584
go towards the

130
00:05:19,144 --> 00:05:21,384
various layers that are involved in the quantum

131
00:05:21,384 --> 00:05:21,884
technology.

132
00:05:22,264 --> 00:05:23,944
You have the building block that is a

133
00:05:23,944 --> 00:05:24,444
qubit.

134
00:05:25,144 --> 00:05:27,485
Just like the transistor was a building block.

135
00:05:27,544 --> 00:05:29,724
Then you have, you put them into circuits

136
00:05:30,024 --> 00:05:32,240
and then you make them into a processor.

137
00:05:32,860 --> 00:05:34,860
The same way we are hoping that quantum

138
00:05:34,860 --> 00:05:37,120
technology will reach a processor level.

139
00:05:37,500 --> 00:05:39,259
And at that level, you have a lot

140
00:05:39,259 --> 00:05:42,139
of scope for computational engineers to sort of

141
00:05:42,139 --> 00:05:44,220
help and improve the designs and things like

142
00:05:44,220 --> 00:05:44,720
that.

143
00:05:45,034 --> 00:05:46,794
So can you talk a bit about some

144
00:05:46,794 --> 00:05:48,735
of the materials that you're investigating

145
00:05:49,194 --> 00:05:51,134
at the moment? What are the hot materials

146
00:05:51,194 --> 00:05:51,935
at the moment

147
00:05:52,394 --> 00:05:52,714
for,

148
00:05:53,354 --> 00:05:57,354
quantum Yeah. Technologies? Yep. So when we talk

149
00:05:57,354 --> 00:05:58,574
about quantum technologies,

150
00:05:59,300 --> 00:06:01,539
the first building block is a qubit or

151
00:06:01,539 --> 00:06:02,599
the quantum bit.

152
00:06:02,979 --> 00:06:05,539
And to realize quantum bit already or the

153
00:06:05,539 --> 00:06:07,879
qubit, there are already many platforms.

154
00:06:08,819 --> 00:06:11,139
I would just trace back to 1926

155
00:06:11,139 --> 00:06:11,959
for a second.

156
00:06:12,339 --> 00:06:13,560
At that point of time,

157
00:06:13,915 --> 00:06:16,975
they predicted that a device called the MOSFET

158
00:06:17,115 --> 00:06:18,975
or what's called metal oxide semiconductor

159
00:06:19,915 --> 00:06:21,295
field effect is possible.

160
00:06:21,754 --> 00:06:23,615
But no one took that for serious,

161
00:06:24,714 --> 00:06:26,370
no one took that to serious notice.

162
00:06:26,850 --> 00:06:29,569
And the bipolar junction transistor was invented in

163
00:06:29,569 --> 00:06:31,589
somewhere around 1949.

164
00:06:31,970 --> 00:06:34,449
And the inventors were back then asked, what

165
00:06:34,449 --> 00:06:35,350
is the application?

166
00:06:35,729 --> 00:06:37,589
Bardeen, Bertain and Shockley.

167
00:06:38,370 --> 00:06:40,884
John Bardeen just came up and said, probably

168
00:06:40,884 --> 00:06:42,805
it's a good amplifier. It can be used

169
00:06:42,805 --> 00:06:43,944
as a hearing aid.

170
00:06:44,324 --> 00:06:46,404
Now you can believe it. The transistor changed

171
00:06:46,404 --> 00:06:47,064
the world.

172
00:06:47,444 --> 00:06:50,004
And I think in nineteen fifties, someone took

173
00:06:50,004 --> 00:06:51,544
up the field effect transistor

174
00:06:52,084 --> 00:06:54,245
and then rest is history. Whatever the patent

175
00:06:54,245 --> 00:06:55,800
was filed in 1924,

176
00:06:56,120 --> 00:06:58,439
in nineteen fifties it came up. So here's

177
00:06:58,439 --> 00:06:59,099
the deal.

178
00:06:59,399 --> 00:07:00,379
Lots of competing

179
00:07:01,000 --> 00:07:04,680
technologies or paradigms exist much before the real

180
00:07:04,680 --> 00:07:06,060
one takes on and becomes

181
00:07:06,519 --> 00:07:09,794
the true, you know, life changing technology. So

182
00:07:09,794 --> 00:07:12,194
at this stage, at the nascent stage, we

183
00:07:12,194 --> 00:07:14,914
have several candidates for the qubits. One is

184
00:07:14,914 --> 00:07:15,574
a superconducting

185
00:07:15,875 --> 00:07:17,814
qubit which is reasonably mature.

186
00:07:18,274 --> 00:07:19,654
We are looking into superconducting

187
00:07:20,035 --> 00:07:22,454
hybrid systems for that purpose to understand

188
00:07:23,149 --> 00:07:26,289
the inner workings of the superconducting qubit device.

189
00:07:27,229 --> 00:07:30,050
And at more exploratory levels or not

190
00:07:30,750 --> 00:07:32,909
not so much nascent, but somewhere in between

191
00:07:32,909 --> 00:07:34,289
we have the silicon qubits

192
00:07:34,909 --> 00:07:38,084
and donor qubits and various types of materials

193
00:07:38,225 --> 00:07:39,764
that are surrounding the silicon.

194
00:07:40,544 --> 00:07:43,524
The ambition is to integrate silicon into cubits.

195
00:07:43,665 --> 00:07:46,884
And so silicon cubits are also quite actively

196
00:07:47,104 --> 00:07:49,425
investigated and we are also doing a lot

197
00:07:49,425 --> 00:07:50,485
of work on understanding

198
00:07:51,199 --> 00:07:52,500
the devices that

199
00:07:52,800 --> 00:07:53,860
make these qubits.

200
00:07:54,639 --> 00:07:57,540
The third one is for other quantum technologies.

201
00:07:58,080 --> 00:08:01,300
Those are technologies that are not just necessarily

202
00:08:01,360 --> 00:08:02,339
qubits but

203
00:08:02,639 --> 00:08:05,220
maybe for single photon detection

204
00:08:05,915 --> 00:08:07,935
or surrounding various other

205
00:08:08,475 --> 00:08:08,975
applications

206
00:08:09,514 --> 00:08:11,454
that come under the quantum umbrella.

207
00:08:11,995 --> 00:08:14,634
You have a lot of materials like tungsten

208
00:08:14,634 --> 00:08:16,814
telluride. So a lot of two d materials

209
00:08:17,035 --> 00:08:18,735
are under a lot of investigation

210
00:08:19,449 --> 00:08:20,589
for various applications

211
00:08:20,889 --> 00:08:23,129
surrounding this whole quantum technology, which we are

212
00:08:23,129 --> 00:08:26,350
also actively looking at. For instance, tungsten telluride

213
00:08:26,810 --> 00:08:28,730
is a material that is known to be

214
00:08:28,730 --> 00:08:30,750
something called a topological insulator.

215
00:08:31,210 --> 00:08:34,429
Now a topological insulator is an interesting material

216
00:08:35,084 --> 00:08:35,824
that sort

217
00:08:36,365 --> 00:08:36,944
of conducts

218
00:08:37,404 --> 00:08:40,365
what is called very pristine edge states that

219
00:08:40,365 --> 00:08:41,084
are not

220
00:08:41,644 --> 00:08:42,784
or that are

221
00:08:43,245 --> 00:08:44,464
that do not have

222
00:08:44,845 --> 00:08:47,024
what you call traditional words dissipation.

223
00:08:47,820 --> 00:08:50,379
Now dissipation is like think about cars in

224
00:08:50,379 --> 00:08:52,300
a traffic and a lot of people around.

225
00:08:52,300 --> 00:08:54,000
Your car cannot go smoothly.

226
00:08:54,379 --> 00:08:55,600
But these are materials

227
00:08:56,139 --> 00:08:58,300
that can go in such an environment, but

228
00:08:58,300 --> 00:09:00,460
on the edges, they conduct so well that

229
00:09:00,460 --> 00:09:02,240
it's almost like edges of freeways

230
00:09:02,694 --> 00:09:03,514
where you go

231
00:09:04,375 --> 00:09:06,615
without scattering with anyone. But the bulk of

232
00:09:06,615 --> 00:09:09,674
the material is like a crowded road.

233
00:09:10,134 --> 00:09:12,855
So this kind of a new material gives

234
00:09:12,855 --> 00:09:15,894
you very interesting properties which can be used

235
00:09:15,894 --> 00:09:17,754
for various quantum applications.

236
00:09:18,379 --> 00:09:20,720
It can also be used for classical applications.

237
00:09:20,860 --> 00:09:23,179
So these are the classes of materials we

238
00:09:23,179 --> 00:09:25,179
look at. And the word is a nice

239
00:09:25,179 --> 00:09:27,440
word for these. It's called quantum materials.

240
00:09:28,299 --> 00:09:30,379
Now you might ask every material could be

241
00:09:30,379 --> 00:09:31,815
quantum. The answer is

242
00:09:32,455 --> 00:09:33,514
it's not like that.

243
00:09:34,375 --> 00:09:36,634
Quantum materials are special because

244
00:09:37,095 --> 00:09:39,174
you can see their if I can we

245
00:09:39,174 --> 00:09:40,634
finally use the word, quantumness

246
00:09:41,575 --> 00:09:44,455
at longer length scales. For instance, when you

247
00:09:44,455 --> 00:09:47,829
measure the resistance of a topological material, it

248
00:09:47,829 --> 00:09:49,449
will show you something that's quantized

249
00:09:50,149 --> 00:09:50,649
at

250
00:09:51,190 --> 00:09:53,589
there's a standard number for that. But yeah.

251
00:09:53,589 --> 00:09:55,529
So it will show you a quantized resistance

252
00:09:56,070 --> 00:09:58,490
and things like that. So these are materials

253
00:09:58,870 --> 00:10:01,350
that can be used for various surrounding quantum

254
00:10:01,350 --> 00:10:01,850
technologies

255
00:10:02,845 --> 00:10:03,665
That include,

256
00:10:04,524 --> 00:10:05,585
photon detection

257
00:10:07,325 --> 00:10:08,065
and materials.

258
00:10:08,445 --> 00:10:11,904
They could be also what's called peripheral technologies,

259
00:10:12,205 --> 00:10:15,600
the qubit technologies and various things like that.

260
00:10:15,839 --> 00:10:18,240
So we are at an exciting phase and

261
00:10:18,240 --> 00:10:20,240
world is changing rapidly. There are lots of

262
00:10:20,240 --> 00:10:21,459
materials to investigate.

263
00:10:21,839 --> 00:10:24,159
And every day there's a new breakthrough and

264
00:10:24,159 --> 00:10:26,000
we hope to sort of ride the wave

265
00:10:26,000 --> 00:10:28,319
with our research. Right. And and and what

266
00:10:28,319 --> 00:10:30,500
about at the at the device level?

267
00:10:30,914 --> 00:10:33,075
What what what sort of devices are you

268
00:10:33,075 --> 00:10:35,095
are you interested in studying

269
00:10:35,475 --> 00:10:37,394
from a computational point of view at the

270
00:10:37,394 --> 00:10:37,894
moment?

271
00:10:38,355 --> 00:10:39,414
Yes. Thank you.

272
00:10:39,875 --> 00:10:42,774
So the devices I work on are specifically

273
00:10:43,714 --> 00:10:46,320
related to two things. One is the qubits

274
00:10:46,320 --> 00:10:47,460
stem cells. How

275
00:10:47,840 --> 00:10:50,340
how to make better qubits with the existing

276
00:10:50,480 --> 00:10:52,320
devices. So in that sense, we look at

277
00:10:52,320 --> 00:10:54,100
what is called quantum dot devices.

278
00:10:55,039 --> 00:10:57,279
These devices can host what is called, for

279
00:10:57,279 --> 00:11:00,580
instance, silicon qubits or spin qubits.

280
00:11:00,975 --> 00:11:02,815
These are one type of qubit. As I

281
00:11:02,815 --> 00:11:04,514
said, there are many competing qubit

282
00:11:04,975 --> 00:11:06,894
technologies. The other devices we look at are

283
00:11:06,894 --> 00:11:09,774
superconducting hybrid systems as I said. One of

284
00:11:09,774 --> 00:11:11,934
which is a reasonably mature technology, it's called

285
00:11:11,934 --> 00:11:14,834
the transmon qubit, which is based on superconductors.

286
00:11:15,480 --> 00:11:17,820
There are other qubits that are also being

287
00:11:17,879 --> 00:11:18,779
currently investigated.

288
00:11:19,720 --> 00:11:23,240
And there are many advantages slash disadvantages at

289
00:11:23,240 --> 00:11:24,779
at the level of each platform.

290
00:11:25,320 --> 00:11:27,159
So one of the things that would come

291
00:11:27,159 --> 00:11:29,325
up next is a hybrid quantum system that

292
00:11:29,325 --> 00:11:31,665
could actually leverage the advantages of various

293
00:11:32,205 --> 00:11:33,825
types of, systems,

294
00:11:34,365 --> 00:11:36,764
bring them together for a quantum processing. So

295
00:11:36,764 --> 00:11:38,285
in that sense, we are looking at two

296
00:11:38,285 --> 00:11:39,825
d materials for qubits.

297
00:11:40,205 --> 00:11:42,700
We are looking at spin qubits at silicon

298
00:11:42,700 --> 00:11:45,100
level. We are also looking at superconducting hybrid

299
00:11:45,100 --> 00:11:45,600
systems

300
00:11:46,139 --> 00:11:48,540
at a broad level for various other competing

301
00:11:48,540 --> 00:11:49,440
qubit paradigms.

302
00:11:50,220 --> 00:11:53,180
Yeah. I see. And one of the,

303
00:11:54,164 --> 00:11:55,464
sort of early applications,

304
00:11:55,764 --> 00:11:57,945
I suppose, of quantum computers

305
00:11:58,565 --> 00:11:59,625
is doing

306
00:12:00,084 --> 00:12:00,584
simulations

307
00:12:01,365 --> 00:12:02,184
of materials

308
00:12:02,644 --> 00:12:05,945
because, of course, materials are quantum in nature.

309
00:12:06,269 --> 00:12:09,550
And it it in some cases, it's easier

310
00:12:09,550 --> 00:12:11,810
to do the simulation on a quantum computer,

311
00:12:12,029 --> 00:12:14,269
if you had one, than it would be

312
00:12:14,269 --> 00:12:16,750
on a classical computer. Is that something that

313
00:12:16,750 --> 00:12:17,889
you're you're actively

314
00:12:18,670 --> 00:12:21,090
looking at at the moment, actually using

315
00:12:21,654 --> 00:12:24,855
nascent quantum computers to do some of your

316
00:12:24,855 --> 00:12:27,495
computational work? Or is that is that something

317
00:12:27,495 --> 00:12:28,634
from for the future,

318
00:12:29,414 --> 00:12:31,035
with regards to your research?

319
00:12:31,815 --> 00:12:33,894
Yes. So thank you for this question. So

320
00:12:33,894 --> 00:12:34,715
there are many,

321
00:12:35,414 --> 00:12:37,570
let's say there are many aspects to your

322
00:12:37,570 --> 00:12:40,289
question. The first part was more to do

323
00:12:40,289 --> 00:12:43,490
with simulating materials. Right? So that is often

324
00:12:43,490 --> 00:12:46,610
called quantum simulations. That's a word for it.

325
00:12:46,610 --> 00:12:48,470
So you can simulate a hypothetical

326
00:12:49,250 --> 00:12:49,750
material.

327
00:12:50,315 --> 00:12:52,394
For instance, there is there was there were

328
00:12:52,394 --> 00:12:53,934
some materials that people

329
00:12:54,475 --> 00:12:56,954
predicted in theory that really don't come as

330
00:12:56,954 --> 00:12:57,534
a material.

331
00:12:57,914 --> 00:12:59,914
For instance, there's something called the Kita f

332
00:12:59,914 --> 00:13:02,235
chain, which is supposed to have what's called

333
00:13:02,235 --> 00:13:03,534
a p wave superconductivity.

334
00:13:04,235 --> 00:13:05,534
Doesn't exist in nature.

335
00:13:05,899 --> 00:13:08,379
Right? There's another chain called some of these

336
00:13:08,379 --> 00:13:10,940
materials they are they have something called SSI

337
00:13:10,940 --> 00:13:13,740
chain. Many of these materials don't exist in

338
00:13:13,740 --> 00:13:17,120
nature. But you can simulate them using quantum,

339
00:13:17,884 --> 00:13:18,865
for instance, quantum

340
00:13:19,245 --> 00:13:21,325
computer. Not just a quantum computer but you

341
00:13:21,325 --> 00:13:24,284
can simulate them by aligning materials in a

342
00:13:24,284 --> 00:13:24,784
row

343
00:13:25,164 --> 00:13:27,725
trying to achieve that Hamiltonian. That is called

344
00:13:27,725 --> 00:13:28,784
a quantum simulation.

345
00:13:29,325 --> 00:13:31,589
However, if you're asking about how we use

346
00:13:31,589 --> 00:13:34,089
the quantum computer to do some of our

347
00:13:34,309 --> 00:13:36,649
device simulations, the answer is no yet.

348
00:13:37,029 --> 00:13:39,690
We do not we do not yet simulate

349
00:13:39,750 --> 00:13:42,549
these things. And there are quantum computers I

350
00:13:42,549 --> 00:13:45,285
know. And probably you can fire simulations

351
00:13:45,985 --> 00:13:47,764
using Qiskit and other softwares.

352
00:13:48,144 --> 00:13:50,225
But those are more about trying out certain

353
00:13:50,225 --> 00:13:51,125
quantum algorithms.

354
00:13:51,985 --> 00:13:54,065
And some people can, you know, run a

355
00:13:54,065 --> 00:13:55,379
search algorithm or

356
00:13:55,779 --> 00:13:58,019
one of these famous six algorithms are there,

357
00:13:58,019 --> 00:13:59,080
four or five algorithms.

358
00:13:59,620 --> 00:14:01,860
You could try out those algorithms on quantum

359
00:14:01,860 --> 00:14:04,100
computers. That's what at the back end. So

360
00:14:04,100 --> 00:14:05,879
that's probably what I think

361
00:14:06,259 --> 00:14:07,000
is there

362
00:14:07,379 --> 00:14:08,519
out is out there.

363
00:14:08,865 --> 00:14:11,105
I'm not sure if we have done anything

364
00:14:11,105 --> 00:14:13,424
on those fronts because we directly simulate the

365
00:14:13,424 --> 00:14:14,725
physics of the devices.

366
00:14:15,184 --> 00:14:16,085
So for instance,

367
00:14:16,784 --> 00:14:18,865
the main let's say I would call the

368
00:14:18,865 --> 00:14:21,445
protagonist of all these stories is the electrons

369
00:14:21,504 --> 00:14:24,329
for us. Electrons are the subatomic particles that

370
00:14:24,329 --> 00:14:26,649
carry electric current. Right? The reason you have

371
00:14:26,649 --> 00:14:28,329
electricity is electrons. The reason you have a

372
00:14:28,329 --> 00:14:29,870
computer eventually is electrons.

373
00:14:30,570 --> 00:14:33,450
And, so the quantum devices some of the

374
00:14:33,450 --> 00:14:36,029
quantum devices that could form quantum computers

375
00:14:36,394 --> 00:14:38,894
or what's called solid state quantum computers

376
00:14:39,514 --> 00:14:40,014
would

377
00:14:40,475 --> 00:14:43,455
depend on electrons. So we simulate and understand

378
00:14:43,674 --> 00:14:44,174
electron

379
00:14:44,955 --> 00:14:48,095
motion or electron transport across these devices.

380
00:14:48,554 --> 00:14:49,534
And that's precisely

381
00:14:50,120 --> 00:14:52,459
what we use mathematical models to simulate.

382
00:14:53,079 --> 00:14:55,480
And that at that level, we probably don't

383
00:14:55,480 --> 00:14:56,779
need a quantum computer

384
00:14:57,480 --> 00:14:59,879
to understand or speed up our algorithms. We'd

385
00:14:59,879 --> 00:15:02,759
rather use standard GPU type, you know, speed

386
00:15:02,759 --> 00:15:05,304
ups, which are good enough. Yeah.

387
00:15:05,684 --> 00:15:09,144
I see. Okay. And and this year, 2025,

388
00:15:09,204 --> 00:15:10,264
is the international

389
00:15:10,644 --> 00:15:11,144
year

390
00:15:11,524 --> 00:15:12,264
of quantum.

391
00:15:12,964 --> 00:15:14,345
And what we're doing here

392
00:15:14,725 --> 00:15:16,964
at Physics World is we're asking as many

393
00:15:16,964 --> 00:15:18,584
physicists as we can,

394
00:15:19,409 --> 00:15:20,309
one question.

395
00:15:21,490 --> 00:15:22,950
And that question is,

396
00:15:23,330 --> 00:15:25,830
what does quantum physics mean to you?

397
00:15:28,210 --> 00:15:28,710
Well,

398
00:15:29,090 --> 00:15:29,990
I have been

399
00:15:31,250 --> 00:15:32,309
studying quantum

400
00:15:33,009 --> 00:15:33,669
in devices

401
00:15:34,315 --> 00:15:35,774
since 02/2003.

402
00:15:36,235 --> 00:15:37,934
So much before the quantum,

403
00:15:39,355 --> 00:15:39,855
technology

404
00:15:41,195 --> 00:15:42,174
impeded started.

405
00:15:42,794 --> 00:15:44,014
So in that sense,

406
00:15:44,315 --> 00:15:46,475
I am an electrical engineer to begin with.

407
00:15:46,475 --> 00:15:46,975
And

408
00:15:47,840 --> 00:15:49,379
when I started my PhD,

409
00:15:49,840 --> 00:15:52,320
the the corridors of my depart of the

410
00:15:52,320 --> 00:15:54,820
region I was working on was always resonating

411
00:15:54,960 --> 00:15:55,620
with Hamiltonian,

412
00:15:56,639 --> 00:15:57,139
Quantum.

413
00:15:57,600 --> 00:15:59,360
And I got used to that. So Quantum

414
00:15:59,360 --> 00:16:02,205
means everything to me. And I believe,

415
00:16:02,825 --> 00:16:03,325
the

416
00:16:03,945 --> 00:16:06,845
quantum revolution, if it happens, can be

417
00:16:07,384 --> 00:16:07,884
disruptive.

418
00:16:08,585 --> 00:16:11,945
And I'm really hoping that quantum technologies take

419
00:16:11,945 --> 00:16:12,445
up.

420
00:16:12,839 --> 00:16:15,659
I'm not sure if only computing is the

421
00:16:15,799 --> 00:16:19,019
thing. Computing will definitely speed up certain algorithms,

422
00:16:19,079 --> 00:16:19,819
no doubt.

423
00:16:20,199 --> 00:16:21,019
But I think

424
00:16:21,720 --> 00:16:24,440
surrounding quantum computing is a bunch of quantum

425
00:16:24,440 --> 00:16:25,339
enhanced technologies,

426
00:16:26,274 --> 00:16:27,715
sensing, as well as,

427
00:16:29,075 --> 00:16:29,575
communications

428
00:16:30,034 --> 00:16:33,254
and various other aspects of surrounding quantum.

429
00:16:33,634 --> 00:16:36,115
I'm sure if all this come together, we

430
00:16:36,115 --> 00:16:37,254
should have a great

431
00:16:38,000 --> 00:16:40,959
by twenty forties and early twenty fifties, next

432
00:16:40,959 --> 00:16:42,959
century. Sorry. The the second half of the

433
00:16:42,959 --> 00:16:44,959
century can be, I mean, can be a

434
00:16:44,959 --> 00:16:45,779
very disruptive,

435
00:16:46,959 --> 00:16:48,259
technology for humankind.

436
00:16:48,799 --> 00:16:50,100
So quantum is

437
00:16:50,639 --> 00:16:52,820
means everything to me at least. Yeah.

438
00:16:53,404 --> 00:16:55,085
Well, that's great. Thanks. Thanks so much for

439
00:16:55,085 --> 00:16:56,865
coming on the podcast. Thank you.

440
00:16:57,165 --> 00:16:58,705
It was my pleasure. Thank you.

441
00:17:06,619 --> 00:17:07,840
That was Bhaskaran

442
00:17:08,380 --> 00:17:08,880
Muralidharan

443
00:17:09,820 --> 00:17:12,480
of the Indian Institute of Technology,

444
00:17:12,940 --> 00:17:13,440
Bombay.

445
00:17:14,220 --> 00:17:16,960
He's on the editorial board of the journal

446
00:17:17,340 --> 00:17:17,840
Materials

447
00:17:18,220 --> 00:17:19,680
for Quantum Technology.

448
00:17:20,644 --> 00:17:23,065
It's published by IOP Publishing,

449
00:17:23,524 --> 00:17:26,345
which also brings you Physics World.

450
00:17:27,284 --> 00:17:27,784
Now

451
00:17:28,085 --> 00:17:30,184
moving on to medical physics.

452
00:17:30,804 --> 00:17:33,865
The second segment of this podcast episode

453
00:17:34,410 --> 00:17:37,390
features an interview with the medical ultrasound

454
00:17:37,850 --> 00:17:38,350
expert,

455
00:17:38,730 --> 00:17:39,789
Daniel Sarno,

456
00:17:40,330 --> 00:17:42,190
who is based at The UK's

457
00:17:42,650 --> 00:17:44,269
National Physical Laboratory.

458
00:17:45,210 --> 00:17:46,670
Here he is in conversation

459
00:17:47,210 --> 00:17:49,470
with Physics World's Tammy Freeman.

460
00:17:50,414 --> 00:17:53,134
They look at the role that ultrasound can

461
00:17:53,134 --> 00:17:54,674
play in diagnosing

462
00:17:55,215 --> 00:17:56,035
breast cancer.

463
00:18:04,369 --> 00:18:07,330
Mammography is an effective tool for detecting breast

464
00:18:07,330 --> 00:18:10,070
cancer, and it's widely used in screening programs.

465
00:18:10,690 --> 00:18:11,509
But mammography

466
00:18:11,809 --> 00:18:14,450
exposes patients to X-ray radiation, and it doesn't

467
00:18:14,450 --> 00:18:16,529
work well in dense tissue, which can hide

468
00:18:16,529 --> 00:18:17,910
the presence of a tumor.

469
00:18:19,035 --> 00:18:21,695
Researchers at The UK's National Physical Laboratory

470
00:18:22,234 --> 00:18:25,035
have developed an ultrasound based system that can

471
00:18:25,035 --> 00:18:28,174
provide safe, low cost breast density assessment,

472
00:18:28,634 --> 00:18:30,634
and NPL is now looking to spin out

473
00:18:30,634 --> 00:18:33,674
a company, Sona, to bring this technology to

474
00:18:33,674 --> 00:18:34,174
market.

475
00:18:34,829 --> 00:18:36,849
I'm speaking today with Daniel Sarno,

476
00:18:37,230 --> 00:18:40,589
Sona's cofounder and chief technology officer. Welcome to

477
00:18:40,589 --> 00:18:41,730
the podcast, Daniel.

478
00:18:42,349 --> 00:18:43,730
Hi. Thanks for having me.

479
00:18:44,429 --> 00:18:47,069
So can we start by looking at what

480
00:18:47,069 --> 00:18:47,809
are the limitations

481
00:18:48,190 --> 00:18:49,409
of current mammography

482
00:18:49,710 --> 00:18:51,164
based cancer screening?

483
00:18:52,265 --> 00:18:53,325
Screening in general

484
00:18:53,625 --> 00:18:55,944
as a, as a tool used by health

485
00:18:55,944 --> 00:18:56,605
care systems

486
00:18:57,144 --> 00:18:58,444
aims at detecting

487
00:18:59,305 --> 00:19:03,005
early signs of cancer in mostly asymptomatic populations.

488
00:19:03,785 --> 00:19:05,849
So breast cancer screening, for instance,

489
00:19:06,329 --> 00:19:08,269
in The UK, at least is

490
00:19:08,650 --> 00:19:11,450
offered for women aged 50 onwards every three

491
00:19:11,450 --> 00:19:11,950
years.

492
00:19:12,890 --> 00:19:13,950
And the

493
00:19:14,410 --> 00:19:15,929
the reason why we do this is that

494
00:19:15,929 --> 00:19:17,849
the breast cancer is the most common cause

495
00:19:17,849 --> 00:19:18,750
of cancer,

496
00:19:19,289 --> 00:19:19,789
in

497
00:19:20,089 --> 00:19:20,990
women worldwide.

498
00:19:21,744 --> 00:19:22,244
There's

499
00:19:22,625 --> 00:19:24,865
over three point three million new cases each

500
00:19:24,865 --> 00:19:25,365
year.

501
00:19:25,825 --> 00:19:27,904
And in The UK, there are about fifty

502
00:19:27,904 --> 00:19:28,884
seven thousand

503
00:19:29,424 --> 00:19:31,525
new cases with increasing rates

504
00:19:31,904 --> 00:19:33,284
mainly in younger women.

505
00:19:34,470 --> 00:19:36,549
Now the reason why we do screening is

506
00:19:36,549 --> 00:19:37,769
that we want to detect

507
00:19:38,309 --> 00:19:39,690
breast cancer earlier.

508
00:19:39,990 --> 00:19:42,309
If we detect breast cancer earlier, particularly at

509
00:19:42,309 --> 00:19:42,809
stage

510
00:19:43,109 --> 00:19:45,210
one, so when cancers are localized,

511
00:19:45,910 --> 00:19:48,464
survival rates are near a hundred percent is

512
00:19:48,784 --> 00:19:50,565
incredibly survivable cancer.

513
00:19:52,144 --> 00:19:54,804
Issue is when cancers are dissected much later

514
00:19:55,265 --> 00:19:56,005
in stages

515
00:19:56,384 --> 00:19:56,784
four

516
00:19:57,265 --> 00:20:00,244
in predominantly stage four where cancers have metastasized

517
00:20:00,464 --> 00:20:02,190
and gone to multiple sites,

518
00:20:03,149 --> 00:20:05,549
where survival rates then dropped sadly to as

519
00:20:05,549 --> 00:20:06,929
low as twenty two percent,

520
00:20:07,629 --> 00:20:08,609
in some countries.

521
00:20:09,789 --> 00:20:12,369
So screening aims to find cancer

522
00:20:12,829 --> 00:20:14,204
earlier when it's more treatable.

523
00:20:15,644 --> 00:20:17,565
Treatable. And like I said, for most women,

524
00:20:17,565 --> 00:20:18,384
it's offered

525
00:20:19,005 --> 00:20:20,924
at either 40 or 50 depending on what

526
00:20:20,924 --> 00:20:22,144
country you live in.

527
00:20:24,284 --> 00:20:27,599
With the main tool that's used is, mammography.

528
00:20:27,819 --> 00:20:30,799
So mammography is a X-ray based

529
00:20:31,099 --> 00:20:31,599
imaging

530
00:20:32,059 --> 00:20:32,559
system.

531
00:20:33,819 --> 00:20:34,319
Most

532
00:20:34,619 --> 00:20:35,119
notably,

533
00:20:35,980 --> 00:20:37,659
requires compression of the brass, which is sort

534
00:20:37,659 --> 00:20:39,259
of what most people think of when they

535
00:20:39,259 --> 00:20:40,079
think of mammography.

536
00:20:41,154 --> 00:20:43,174
The issue actually is that

537
00:20:43,555 --> 00:20:45,095
different breasts have different

538
00:20:45,394 --> 00:20:45,894
compositions.

539
00:20:46,434 --> 00:20:47,575
Some women have

540
00:20:48,035 --> 00:20:50,674
higher amount of fibro glandular tissue in the

541
00:20:50,674 --> 00:20:53,414
breast. Some women have more fatty breast tissue.

542
00:20:54,035 --> 00:20:55,279
But mammography

543
00:20:55,740 --> 00:20:56,240
performance

544
00:20:57,259 --> 00:20:59,440
really depends on breast composition.

545
00:20:59,900 --> 00:21:02,059
Women with the highest density of breast, that's

546
00:21:02,059 --> 00:21:04,160
to say, women with mostly

547
00:21:04,700 --> 00:21:06,000
fibro glandular tissue,

548
00:21:07,259 --> 00:21:08,559
the performance of mammography

549
00:21:09,019 --> 00:21:09,519
diminishes

550
00:21:09,944 --> 00:21:10,444
drastically.

551
00:21:11,544 --> 00:21:13,724
For women with batty breast tissue,

552
00:21:14,744 --> 00:21:17,304
mammography the sensitivity of mammography, which is sort

553
00:21:17,304 --> 00:21:17,964
of the

554
00:21:18,424 --> 00:21:20,345
the metric by which you can assess the

555
00:21:20,345 --> 00:21:22,505
performance of this tool, is as high as

556
00:21:22,505 --> 00:21:23,724
ninety percent. So

557
00:21:24,660 --> 00:21:26,420
most of the cancers that are present in

558
00:21:26,420 --> 00:21:29,460
women with the lowest density breast tissue are

559
00:21:29,460 --> 00:21:30,519
picked up by mammography.

560
00:21:31,299 --> 00:21:34,359
For women with, highest breast density categories,

561
00:21:34,980 --> 00:21:37,775
the performance of mammography drops to as low

562
00:21:37,775 --> 00:21:38,914
as 50%

563
00:21:39,454 --> 00:21:39,954
sensitivity.

564
00:21:40,575 --> 00:21:42,355
That's to say, if a cancer is present,

565
00:21:42,654 --> 00:21:44,335
almost half of the time, it will be

566
00:21:44,335 --> 00:21:44,835
missed.

567
00:21:45,214 --> 00:21:45,954
But the

568
00:21:46,414 --> 00:21:49,519
onset con consequence of that being that cancer

569
00:21:49,519 --> 00:21:50,740
is picked up later

570
00:21:51,519 --> 00:21:53,619
or in a kind of a subsequent screening

571
00:21:53,839 --> 00:21:54,339
opportunity.

572
00:21:55,440 --> 00:21:55,940
Now

573
00:21:56,559 --> 00:21:59,200
this limitation of mammography has been known for

574
00:21:59,200 --> 00:22:00,099
a long time,

575
00:22:01,119 --> 00:22:04,595
but it mammography still remains the best tool

576
00:22:04,595 --> 00:22:07,255
we have. It's the gold standard tool for

577
00:22:07,555 --> 00:22:09,095
breast cancer screening.

578
00:22:09,555 --> 00:22:11,795
But there are other tools out there, other

579
00:22:11,795 --> 00:22:13,654
modalities for breast cancer screening.

580
00:22:14,515 --> 00:22:16,410
Some of them being ultrasound based.

581
00:22:16,890 --> 00:22:18,730
There is MRI, which is,

582
00:22:19,369 --> 00:22:20,590
obviously, a very costly

583
00:22:20,970 --> 00:22:21,630
but effective

584
00:22:22,490 --> 00:22:22,990
tool.

585
00:22:23,450 --> 00:22:26,349
There's other there's different types of mammography, such

586
00:22:26,730 --> 00:22:27,549
as, tomosynthesis,

587
00:22:28,330 --> 00:22:30,170
a a a version of mammography that's sort

588
00:22:30,170 --> 00:22:32,575
of this pseudo three d imaging,

589
00:22:33,434 --> 00:22:36,494
and contrast enhanced mammography. So there's a plethora

590
00:22:36,555 --> 00:22:37,934
of tools beyond mammography

591
00:22:38,634 --> 00:22:39,455
that can be,

592
00:22:39,835 --> 00:22:42,555
used as screening for women with different breast

593
00:22:42,555 --> 00:22:43,055
densities.

594
00:22:44,150 --> 00:22:44,789
Okay. So,

595
00:22:45,429 --> 00:22:48,710
Sona is developing the ultrasound based approach. So

596
00:22:48,710 --> 00:22:51,769
what what are the advantage advantages of ultrasound

597
00:22:51,990 --> 00:22:53,690
scans over X-ray imaging?

598
00:22:55,190 --> 00:22:57,509
Yeah. So what we're doing at Sona is

599
00:22:57,509 --> 00:22:58,169
we're actually

600
00:22:59,795 --> 00:23:02,295
providing a tool or developing a tool

601
00:23:02,835 --> 00:23:05,654
that can do breast density assessment. So this

602
00:23:06,275 --> 00:23:08,994
is not breast cancer screening. So we're we're

603
00:23:08,994 --> 00:23:11,734
not trying to do the job of mammography

604
00:23:11,955 --> 00:23:13,049
in trying to detect

605
00:23:13,450 --> 00:23:15,230
cancers at the earliest,

606
00:23:16,730 --> 00:23:17,230
stages.

607
00:23:17,690 --> 00:23:19,390
Instead, we're trying to measure

608
00:23:19,930 --> 00:23:20,430
global,

609
00:23:21,210 --> 00:23:22,990
metrics of breast composition

610
00:23:23,769 --> 00:23:26,170
such that women can be provided with the

611
00:23:26,170 --> 00:23:28,855
right forms of breast cancer screening at the

612
00:23:28,855 --> 00:23:31,095
right time for them based off their breast

613
00:23:31,095 --> 00:23:31,595
composition.

614
00:23:32,934 --> 00:23:34,795
And some of the advantages of,

615
00:23:35,575 --> 00:23:38,075
of ultrasound over X-ray imaging

616
00:23:38,535 --> 00:23:40,420
is that, of course, the kind of natural

617
00:23:40,420 --> 00:23:41,619
one that I think most people would think

618
00:23:41,619 --> 00:23:44,200
of is the X-ray imaging is a ionizing

619
00:23:44,660 --> 00:23:46,279
based imaging tool.

620
00:23:46,900 --> 00:23:50,580
This limits its use both in kind of

621
00:23:50,580 --> 00:23:51,640
setting that these,

622
00:23:52,259 --> 00:23:54,119
mammogram scans can be provided,

623
00:23:54,464 --> 00:23:56,644
but also the frequency with which

624
00:23:57,025 --> 00:23:58,884
mammogram imaging can be provided.

625
00:24:00,625 --> 00:24:01,525
But ultrasound,

626
00:24:02,065 --> 00:24:04,644
in contrast, is a safe tool.

627
00:24:05,025 --> 00:24:06,005
It's non ionizing.

628
00:24:06,865 --> 00:24:08,085
It's, accessible

629
00:24:08,464 --> 00:24:09,204
and portable.

630
00:24:09,559 --> 00:24:12,220
It's actually it's the second most commonly used

631
00:24:12,359 --> 00:24:14,220
imaging modality worldwide.

632
00:24:14,919 --> 00:24:16,859
So it's very pervasive for that reason.

633
00:24:18,039 --> 00:24:20,679
Okay. And can you explain how your system

634
00:24:20,679 --> 00:24:23,579
actually uses the ultrasound to measure tissue density?

635
00:24:25,214 --> 00:24:27,474
Tissue density, breast density in particular,

636
00:24:30,095 --> 00:24:33,694
to repeat, is important for to understand for

637
00:24:33,694 --> 00:24:34,674
two reasons.

638
00:24:35,775 --> 00:24:36,275
Firstly,

639
00:24:37,375 --> 00:24:38,835
breast high breast density

640
00:24:39,134 --> 00:24:40,115
actually increases

641
00:24:40,650 --> 00:24:43,609
cancer risk. Seventy percent of all cancers are

642
00:24:43,609 --> 00:24:46,109
detected in women with dense breasts.

643
00:24:47,130 --> 00:24:48,109
Now how pervasive

644
00:24:48,570 --> 00:24:49,950
is is breast density?

645
00:24:50,330 --> 00:24:51,070
Well, about

646
00:24:51,690 --> 00:24:53,609
half of all women over the age of

647
00:24:53,609 --> 00:24:55,630
40 have dense breasts. It it varies

648
00:24:56,255 --> 00:24:59,154
from individual to individual and varies with age,

649
00:24:59,294 --> 00:25:01,315
but about half of all women have

650
00:25:01,694 --> 00:25:02,674
high breast density.

651
00:25:03,694 --> 00:25:06,014
It increases cancer risk, so women with the

652
00:25:06,014 --> 00:25:07,794
highest category of breast density

653
00:25:08,190 --> 00:25:10,190
can be up to six times more likely

654
00:25:10,190 --> 00:25:12,269
to develop breast cancer than women with the

655
00:25:12,269 --> 00:25:13,809
lowest category of breast density.

656
00:25:14,589 --> 00:25:17,069
But just to repeat, the the other impacts

657
00:25:17,069 --> 00:25:19,710
of high breast density is this this effect

658
00:25:19,710 --> 00:25:22,349
that it has in reducing the performance of

659
00:25:22,349 --> 00:25:26,105
mammography. So high breast density can mask answers

660
00:25:26,105 --> 00:25:27,164
on screening mammograms

661
00:25:27,625 --> 00:25:28,924
and reduces performance.

662
00:25:30,265 --> 00:25:31,964
Breastness is currently assessed

663
00:25:33,545 --> 00:25:36,445
at screen at the screening opportunity using mammogram

664
00:25:36,505 --> 00:25:39,400
images. So a mammogram image will be,

665
00:25:39,940 --> 00:25:42,500
taken of an individual going through screening. That

666
00:25:42,500 --> 00:25:44,759
mammogram image can be used

667
00:25:45,299 --> 00:25:48,019
to find any cancers present in the breast

668
00:25:48,019 --> 00:25:48,519
tissue.

669
00:25:48,980 --> 00:25:50,994
But, also, the image can be looked at

670
00:25:50,994 --> 00:25:54,055
globally by either a clinician or software interpretation

671
00:25:54,994 --> 00:25:55,654
to see

672
00:25:56,355 --> 00:25:57,255
by either

673
00:25:57,555 --> 00:25:59,894
visually by eye or or by using algorithms

674
00:26:00,595 --> 00:26:02,914
the ratio of fat to fibroblegial tissue and

675
00:26:02,914 --> 00:26:05,015
give a metric for breast density.

676
00:26:06,130 --> 00:26:06,450
That's

677
00:26:07,089 --> 00:26:07,829
it has

678
00:26:08,130 --> 00:26:08,630
proven

679
00:26:09,009 --> 00:26:09,509
incredibly

680
00:26:09,809 --> 00:26:10,309
useful.

681
00:26:11,250 --> 00:26:13,589
In fact, the US FDA

682
00:26:14,210 --> 00:26:18,865
recently changed their reporting guidelines for women across

683
00:26:18,865 --> 00:26:21,525
The US to mandate breast density assessment,

684
00:26:22,305 --> 00:26:23,525
across all states,

685
00:26:24,545 --> 00:26:27,265
such that, you know, it it's it's considered

686
00:26:27,265 --> 00:26:29,924
such a an important factor to measure that

687
00:26:30,065 --> 00:26:32,244
The US actually have mandated this reporting.

688
00:26:33,350 --> 00:26:36,070
So the issue with mammogram based breast density

689
00:26:36,070 --> 00:26:36,570
assessment

690
00:26:37,590 --> 00:26:41,210
is that it actually is not particularly consistent.

691
00:26:42,070 --> 00:26:43,610
Studies have found that

692
00:26:43,990 --> 00:26:46,330
breast density assessment done by clinicians

693
00:26:47,075 --> 00:26:49,954
varies depending on which clinician you have. It

694
00:26:49,954 --> 00:26:53,174
varies from screening opportunity to screening opportunity.

695
00:26:54,275 --> 00:26:55,815
And also breast density assessment

696
00:26:56,194 --> 00:26:58,994
with mammography is not accessible. So at the

697
00:26:58,994 --> 00:27:01,349
moment, you only find out if you have

698
00:27:01,650 --> 00:27:02,630
high breast density

699
00:27:03,089 --> 00:27:04,789
at your first screening opportunity.

700
00:27:06,529 --> 00:27:08,929
Now coming from the National Physical Laboratory, we

701
00:27:08,929 --> 00:27:11,190
see that this is a a measurement challenge.

702
00:27:11,835 --> 00:27:13,534
And being an ultrasound scientist

703
00:27:14,234 --> 00:27:16,875
and believing that ultrasound is a particularly useful

704
00:27:16,875 --> 00:27:18,174
technology to use,

705
00:27:18,875 --> 00:27:20,954
we believe that we can do breast density

706
00:27:20,954 --> 00:27:21,454
assessment

707
00:27:21,755 --> 00:27:23,214
using ultrasound measurement.

708
00:27:23,595 --> 00:27:26,210
Now how it works is we do something

709
00:27:26,210 --> 00:27:29,970
known as, global acoustic attenuation measurements of the

710
00:27:29,970 --> 00:27:30,470
breast.

711
00:27:31,250 --> 00:27:34,049
That's to say, how much does the breast

712
00:27:34,049 --> 00:27:34,549
tissue

713
00:27:34,849 --> 00:27:35,349
diminish

714
00:27:36,129 --> 00:27:38,529
their ultrasound signals as they pass through the

715
00:27:38,529 --> 00:27:38,924
breast?

716
00:27:39,884 --> 00:27:42,865
With women with higher breast density having

717
00:27:43,164 --> 00:27:43,664
higher

718
00:27:43,965 --> 00:27:44,945
acoustic attenuation,

719
00:27:46,125 --> 00:27:49,325
properties of the breast tissue compared to women

720
00:27:49,325 --> 00:27:51,025
with lower breast density.

721
00:27:52,285 --> 00:27:53,940
So our system was

722
00:27:54,500 --> 00:27:56,500
developed at the National Physical Laboratory over a

723
00:27:56,500 --> 00:27:57,879
number of years. We've developed

724
00:27:58,259 --> 00:28:01,240
a new form of ultrasound sensor to

725
00:28:01,859 --> 00:28:03,240
measure this property

726
00:28:03,700 --> 00:28:05,319
in a quantitative way.

727
00:28:06,019 --> 00:28:08,704
And what that actually unlocks is the ability

728
00:28:08,765 --> 00:28:09,265
to,

729
00:28:09,644 --> 00:28:10,944
a, measure

730
00:28:11,404 --> 00:28:12,144
breast density,

731
00:28:12,525 --> 00:28:14,464
in a repeatable, consistent way.

732
00:28:15,484 --> 00:28:15,984
But,

733
00:28:16,365 --> 00:28:19,804
b, you're actually able to now monitor breast

734
00:28:19,804 --> 00:28:20,304
density

735
00:28:21,119 --> 00:28:21,940
over time

736
00:28:22,559 --> 00:28:23,059
with,

737
00:28:24,079 --> 00:28:26,160
so rather than just a a single measurement

738
00:28:26,160 --> 00:28:27,059
of breast density,

739
00:28:27,519 --> 00:28:28,900
you're now able to

740
00:28:29,519 --> 00:28:30,900
do repeat measurements,

741
00:28:31,839 --> 00:28:33,140
which have been found

742
00:28:33,519 --> 00:28:36,605
to also relate to breast cancer risk. Women

743
00:28:36,605 --> 00:28:39,244
who whose breast density does not drop as

744
00:28:39,244 --> 00:28:40,144
fast as

745
00:28:40,445 --> 00:28:42,945
you might expect in, across the population

746
00:28:43,325 --> 00:28:45,644
have actually a higher rate of breast cancer

747
00:28:45,644 --> 00:28:46,945
than women who've not.

748
00:28:48,009 --> 00:28:50,089
Okay. So, you could use your system to

749
00:28:50,089 --> 00:28:52,730
sort of track the differences in density over

750
00:28:52,730 --> 00:28:53,230
time,

751
00:28:53,769 --> 00:28:54,269
possibly

752
00:28:54,809 --> 00:28:57,470
starting at a younger age for the screening,

753
00:28:57,529 --> 00:28:58,589
and then you can

754
00:28:58,890 --> 00:29:00,375
interpret those results. And then,

755
00:29:00,934 --> 00:29:03,174
if it looks like someone's more at risk,

756
00:29:03,174 --> 00:29:05,194
would they then be sent on for mammography

757
00:29:05,335 --> 00:29:06,315
screening afterwards?

758
00:29:08,214 --> 00:29:10,234
Exactly. Yeah. So we

759
00:29:10,615 --> 00:29:11,914
we believe that

760
00:29:12,454 --> 00:29:15,275
what's needed for breast cancer screening

761
00:29:15,799 --> 00:29:16,299
is

762
00:29:16,759 --> 00:29:17,259
early

763
00:29:17,799 --> 00:29:19,500
breast cancer risk assessment.

764
00:29:20,440 --> 00:29:22,279
At the moment, we can do breast cancer

765
00:29:22,279 --> 00:29:23,019
risk assessment

766
00:29:23,480 --> 00:29:25,660
using factors such as history

767
00:29:26,519 --> 00:29:27,740
or even genetics.

768
00:29:28,715 --> 00:29:31,115
But breast density, because at the moment, it's

769
00:29:31,115 --> 00:29:31,615
done

770
00:29:31,914 --> 00:29:33,295
with mammogram based,

771
00:29:34,955 --> 00:29:35,455
imaging,

772
00:29:36,234 --> 00:29:38,414
cannot be done at an earlier age.

773
00:29:39,035 --> 00:29:39,535
So

774
00:29:40,315 --> 00:29:41,375
with our technology,

775
00:29:41,835 --> 00:29:44,080
you could bring breast density assessment

776
00:29:44,619 --> 00:29:45,119
before

777
00:29:45,420 --> 00:29:45,920
screening

778
00:29:46,700 --> 00:29:47,920
such that you can then

779
00:29:48,460 --> 00:29:52,460
plan an onward personalized screening program that's fit

780
00:29:52,460 --> 00:29:55,820
for the individual rather than just using age

781
00:29:55,820 --> 00:29:56,320
based,

782
00:29:57,099 --> 00:29:58,240
screening profiles.

783
00:29:59,865 --> 00:30:01,305
So, I mean, where would you see these

784
00:30:01,305 --> 00:30:03,785
systems being deployed? Would this be something perhaps

785
00:30:03,785 --> 00:30:05,705
that you're just local doctors that it would

786
00:30:05,705 --> 00:30:07,465
be just sort of part of a a

787
00:30:07,465 --> 00:30:10,265
routine test that women would undergo? Like, whilst

788
00:30:10,265 --> 00:30:12,025
they're too young to actually go into the

789
00:30:12,025 --> 00:30:13,005
screening program,

790
00:30:13,910 --> 00:30:14,789
They they could have this,

791
00:30:15,990 --> 00:30:17,289
measurement taken beforehand.

792
00:30:19,349 --> 00:30:21,289
Yeah. So the the technology that we're developing

793
00:30:21,429 --> 00:30:21,929
is

794
00:30:22,470 --> 00:30:24,970
is incredibly accessible. Like I said, it uses

795
00:30:25,109 --> 00:30:27,734
ultrasound, so it doesn't require a dedicated

796
00:30:28,434 --> 00:30:28,934
facility.

797
00:30:30,514 --> 00:30:31,014
It's

798
00:30:31,634 --> 00:30:34,674
aimed to be a desktop sized device, so

799
00:30:34,674 --> 00:30:35,174
small.

800
00:30:36,274 --> 00:30:36,774
And

801
00:30:37,234 --> 00:30:38,615
that opens up the possibility

802
00:30:39,154 --> 00:30:40,375
of screening.

803
00:30:40,710 --> 00:30:41,109
Of

804
00:30:41,669 --> 00:30:43,049
sorry. Breast density assessment

805
00:30:43,750 --> 00:30:45,690
being much more accessible

806
00:30:46,230 --> 00:30:47,529
than it currently is.

807
00:30:48,390 --> 00:30:50,149
So we aim to have these devices in

808
00:30:50,149 --> 00:30:51,289
primary care clinics,

809
00:30:52,069 --> 00:30:52,569
in,

810
00:30:53,029 --> 00:30:54,649
breast cancer screening programs,

811
00:30:55,829 --> 00:30:56,329
in

812
00:30:56,744 --> 00:30:58,845
remote or low resource areas,

813
00:30:59,224 --> 00:31:01,565
and also a part of work workplace

814
00:31:02,025 --> 00:31:03,644
and community health initiatives.

815
00:31:04,664 --> 00:31:05,384
Okay. So,

816
00:31:06,025 --> 00:31:08,525
has the system been tested in patients yet?

817
00:31:09,630 --> 00:31:12,190
It has. The the the the system and

818
00:31:12,190 --> 00:31:13,730
technology actually has

819
00:31:14,029 --> 00:31:14,849
quite a,

820
00:31:15,470 --> 00:31:16,289
long lineage.

821
00:31:16,910 --> 00:31:17,410
Originally,

822
00:31:17,789 --> 00:31:20,690
as I described, we've developed new sensor technology,

823
00:31:21,390 --> 00:31:23,390
a number of years ago, and we've gone

824
00:31:23,734 --> 00:31:26,555
We've evolved from early proof of concept sensors

825
00:31:27,015 --> 00:31:28,634
through to research platforms

826
00:31:29,174 --> 00:31:29,914
and, initially,

827
00:31:30,375 --> 00:31:34,775
measurement validation in in acoustic materials and breast

828
00:31:34,775 --> 00:31:35,275
phantoms.

829
00:31:37,250 --> 00:31:38,850
A couple years ago, we actually did our

830
00:31:38,850 --> 00:31:40,070
first in person testing

831
00:31:40,529 --> 00:31:41,910
to validate these measurements,

832
00:31:42,850 --> 00:31:44,549
in a few people.

833
00:31:45,809 --> 00:31:48,230
At the moment, we're being supported by the

834
00:31:48,769 --> 00:31:51,029
government office for technology

835
00:31:51,330 --> 00:31:51,830
transfer

836
00:31:52,535 --> 00:31:55,255
and also by the UK Innovation and Science

837
00:31:55,255 --> 00:31:56,075
Seed Fund.

838
00:31:56,535 --> 00:31:59,595
And we're developing a proof of concept

839
00:31:59,894 --> 00:32:00,394
prototype

840
00:32:01,095 --> 00:32:02,075
that will initially

841
00:32:02,454 --> 00:32:03,595
conduct preclinical

842
00:32:03,894 --> 00:32:04,394
testing

843
00:32:04,750 --> 00:32:07,250
and later further in person testing.

844
00:32:07,710 --> 00:32:09,309
And the aim of this system really is

845
00:32:09,309 --> 00:32:11,309
to go from what we've had before, which

846
00:32:11,309 --> 00:32:13,409
is a series of research platforms,

847
00:32:13,950 --> 00:32:16,829
something that's much closer to a clinical ready

848
00:32:16,829 --> 00:32:18,224
device in a,

849
00:32:18,865 --> 00:32:21,424
in a configuration where we could do accessible

850
00:32:21,424 --> 00:32:24,724
breast density assessment using through transmission ultrasound.

851
00:32:26,545 --> 00:32:27,445
Okay. And

852
00:32:28,224 --> 00:32:30,785
so this this company, Sonar, is being set

853
00:32:30,785 --> 00:32:33,859
up basically to bring this technology to the

854
00:32:33,859 --> 00:32:35,159
market. I mean,

855
00:32:35,539 --> 00:32:37,139
can you just sort of quickly update on

856
00:32:37,139 --> 00:32:38,039
how that's progressing?

857
00:32:38,419 --> 00:32:40,339
How long do you think it might take

858
00:32:40,339 --> 00:32:43,000
until the these systems are actually ready for

859
00:32:43,220 --> 00:32:44,279
clinical use?

860
00:32:45,779 --> 00:32:47,319
Yeah. So we're we're we're

861
00:32:47,855 --> 00:32:50,674
we're making some great progress. We understand that

862
00:32:50,815 --> 00:32:51,875
it's very challenging

863
00:32:52,335 --> 00:32:53,875
to bring medical technology

864
00:32:54,335 --> 00:32:56,255
to the market, but we are up for

865
00:32:56,255 --> 00:32:56,914
the challenge.

866
00:32:58,174 --> 00:33:00,480
This sort of technology, we think, will be

867
00:33:00,720 --> 00:33:03,599
able to be deployed in '27 2027

868
00:33:03,599 --> 00:33:04,799
or 2028.

869
00:33:04,799 --> 00:33:06,980
That's what we're we're aiming for,

870
00:33:07,679 --> 00:33:10,079
with this year going through a series of

871
00:33:10,079 --> 00:33:11,220
preclinical testing

872
00:33:11,839 --> 00:33:14,900
and next year into clinical trials and clinical

873
00:33:15,200 --> 00:33:18,255
studies where we will compare our ultrasound based

874
00:33:18,394 --> 00:33:20,894
method for breast density assessment with,

875
00:33:21,515 --> 00:33:25,055
traditional mammogram based methods for breast density assessment.

876
00:33:25,994 --> 00:33:28,075
Now, yep, we know there's a lot of

877
00:33:28,075 --> 00:33:28,559
work,

878
00:33:29,519 --> 00:33:31,620
today to get this to the market,

879
00:33:32,240 --> 00:33:35,140
but, but we're not alone. So we've actually,

880
00:33:35,360 --> 00:33:37,519
this year, brought on a great team of

881
00:33:37,519 --> 00:33:41,860
experienced entrepreneurs and world leaders in ultrasound innovation

882
00:33:42,000 --> 00:33:43,424
and product development,

883
00:33:44,205 --> 00:33:46,464
and importantly, breast radiologists as well.

884
00:33:47,244 --> 00:33:50,205
Excellent. Right. Well, thanks very much. It sounds

885
00:33:50,205 --> 00:33:51,904
like a really promising technology.

886
00:33:53,244 --> 00:33:55,744
And thank you for speaking with us today.

887
00:34:03,830 --> 00:34:06,570
That was Daniel Sarno of NPL

888
00:34:06,950 --> 00:34:07,769
and Sona

889
00:34:08,309 --> 00:34:09,050
in conversation

890
00:34:09,430 --> 00:34:11,530
with Physics World's Tammy Freeman.

891
00:34:12,494 --> 00:34:14,335
I'm afraid that's all the time we have

892
00:34:14,335 --> 00:34:15,554
for this week's podcast.

893
00:34:16,094 --> 00:34:17,234
Thanks to Bhaskaran,

894
00:34:17,775 --> 00:34:18,275
Muralidharan,

895
00:34:19,454 --> 00:34:20,514
Daniel Sarno,

896
00:34:20,815 --> 00:34:23,554
and Tammy Freeman for joining me today.

897
00:34:23,934 --> 00:34:26,494
And a special thanks to our producer, Fred

898
00:34:26,494 --> 00:34:26,994
Isles.

899
00:34:27,690 --> 00:34:30,250
We'll be back again next week. See you

900
00:34:30,250 --> 00:34:30,750
then.
