The first session at the Helgoland 2025 meeting marking the centenary of quantum mechanics began with the four Nobel-prize-winning physicsts in attendance being invited on stage to sign the island’s memorial “gold book” and add a short statement to it.
Anton Zeilinger and Alain Aspect, who shared the 2022 Nobel prize with John Clauser for their work on entanglement and quantum information science, were first up on stage. They were followed by Serge Haroche and David Wineland, who shared the 2012 prize for their work on measuring and manipulating quantum systems.
During the coffee break, the book was placed on display for participants to view and add their own signatures if they wished. Naturally, being the nosey person I am, I was keen to see what the Nobel laureates had written.
Here, for the record, are their comments.
“Great sailing. Great people.” Anton Zeilinger
“C’est une émotion de se trouver à l’endroit où a commencé la méchanique quantique.” Alain Aspect [It’s an emotional feeling to find yourself in the place where quantum mechanics started.]
“Thank you for your warm welcome in Helgoland, an island which is known by all quantum physicists.” Serge Haroche
“An honor to be here.” David Wineland
All the comments made sense to me apart from that of Zeilinger so after the evening’s panel debate on the foundations of quantum mechanics, in which he had taken part, I asked him what the reference to sailing was all about.
Turns out that Zeilinger (as Albert Einstein once was) is a keen sailor in his spare time and he and his wife had come to Helgoland three days before the conference began to see the final stages of a North Sea regatta that takes place in late spring every year.
In fact, Zeilinger explained that the Helgoland meeting had to start on a Tuesday as the day before the venue was host to the regatta’s awards ceremony.
As for the flag, it is that of Helgoland, with the green representing the land, the red for the island’s cliffs and the white for the sand on the beaches.

“This is a birthday party! Happy 100th birthday quantum mechanics,” said Jack Harris from Yale University in the US to whoops and cheers in the banqueting suite of the Hotel Atlantic in Hamburg, Germany.
Harris was addressing the 300 or so physicists attending the Helgoland 2025 conference, which is taking place from 9–14 June to mark Werner Heisenberg’s seminal work on quantum mechanics on the island of Helgoland in the North Sea exactly 100 years ago.
“Heisenberg travelled to Helgoland to escape terrible allergies” Harris told delegates, reminding them of how the young 23-year-old had taken leave of absence from his postdoc supervisor Max Born in Göttingen for the fresh air of the treeless island. “His two weeks there was one of the watershed events in the discovery of quantum mechanics.”
Harris admitted, though, that it’s open to debate if Heisenberg’s fortnight on the island was as significant as is often made out, joking that – like quantum mechanics itself – “there are many interpretations that one can apply to this occasion”.
In one interpretation I hadn’t considered before, Harris pointed out that what might be regarded as an impediment or a disability – Heisenberg’s severe hayfever – turned out to be a positive force for science. “It actually brought him to Helgoland in the first place.”
Harris also took the opportunity to remind the audience of the importance of mentoring and helping each other in science. “How we treat others is as important as what we accomplish”, he said. “Another high standard to keep in mind is that science needs to be international and science needs to be inclusive. I am preaching to the choir but this is important to say out loud.”
Harris’s opening remarks were followed a series of three talks. First was Douglas Stone from Yale University who discussed the historical development of quantum science.
Next up was philosopher of science Elise Crull from the City University of New York, who looked into some of the early debates about the philosophical implications of quantum physics – including the pioneering contributions of Grete Hermann, who Sidney Perkowitz discussed in his recent feature for Physics World.
The final after-dinner speaker was science journalist Philip Ball, who explained how quantum theory developed in 1924–25 in the run-up to Helgoland. He focused, as he did in his recent feature for Physics World, on work carried out by Niels Bohr and others that turned out to be wrong but showed the intense turmoil in physics on the brink of quantum mechanics.
Helgoland 2025 features a packed five days of talks, poster sessions and debates – on the island of Helgoland itself – covering the past, present and future of quantum physics, with five Nobel laureates in attendance. In fact, Harris and his fellow co-organizers – Katharina Kißner, Gesine Murphy, Florian Carle, Theophilus Human and Patrick Hoyer – had so much to squeeze in that they could easily have “filled two or three solid programmes with people from whom we would have loved to hear”.
I’ll see over the next few days on Helgoland if they made the right speaker choices, but things have certainly got off to a good start.

Year 12 students (aged 16 or 17) often do work experience while studying for their A-levels. It can provide valuable insights into what the working world is like and showcase what potential career routes are available. And that’s exactly why I requested to do my week of work experience at the Institute of Physics (IOP).
I’m studying maths, chemistry and physics, with a particular interest in the latter. I’m hoping to study physics or chemical physics at university so was keen to find out how the subject can be applied to business, and get a better understanding of what I want to do in the future. The IOP was therefore a perfect placement for me and here are a few highlights of what I did.
My week at the IOP’s headquarters in London began with a brief introduction to the Institute with the head of science and innovation, Anne Crean, and Katherine Platt, manager for the International Year of Quantum Science and Technology (IYQ). Platt, who planned and supervised my week of activities, then gave me a tour of the building and explained more about the IOP’s work, including how it aims to nurture upcoming physics innovation and projects, and give businesses and physicists resources and support.
My first task was working with Jenny Lovell, project manager in the science and innovation team. While helping her organize the latest round of the IOP’s medals and awards, she explained why the IOP honours the physics community in this way and described the different degrees of achievement that it recognizes.
Next I got to meet the IOP’s chief executive officer Tom Grinyer, and unexpectedly the president-elect Michele Dougherty, who is a space physicist at Imperial College London. They are both inspiring people, who gave me some great advice about how I might go about my future in physics. They talked about the exciting opportunities available as a woman in physics, and how no matter where I start, I can go into many different sectors as the subject is so applicable.
To round off the day, I sat in a meeting about how the science and innovation team can increase engagement, before starting on a presentation I was due to make on Thursday about quantum physics and young people.
My second day began with a series of meetings. First up was the science and innovation team’s weekly stand-up meeting. I then attended a larger staff meeting with most of IOP’s employees, which proved informative and gave me a chance to see how different teams interact with each other. Next was the science and innovation managers’ meeting, where I took the minutes as they spoke.
I then met data science lead, Robert Cocking, who went through his work on data insights. He talked about IOP membership statistics in the UK and Ireland, as well as age and gender splits, and how he can do similar breakdowns for the different areas of special interest (such as quantum physics or astronomy). I found the statistics around the representation of girls in the physics community, specifically at A-level, particularly fascinating as it applies to me. Notably, although a lower percentage of girls take A-level physics compared to boys, a higher proportion of those girls go on to study it at university.
The day ended with some time to work on my presentation and research different universities and pathways I could take once I have finished my A-levels.
It was a steady start to Wednesday as I continued with my presentation and research with Platt’s help. Later in the morning, I attended a meeting with the public engagement team about Mimi’s Tiny Adventure, a children’s book written by Toby Shannon-Smith, public programmes manager at IOP, and illustrated by Pauline Gregory. The book, which is the third in the Mimi’s Adventures series, is part of the IOP’s Limit Less campaign to engage young people in physics, and will be published later this year to coincide with the IYQ. It was interesting to see how the IOP advertises physics to a younger audience and makes it more engaging for them.
Platt and I then had a video call with the Physics World team at IOP Publishing in Bristol, joining for their daily news meeting before having an in-depth chat with the editor-in-chief, Matin Durrani, and feature editors, Tushna Commissariat and Sarah Tesh. After giving me a brief introduction to the magazine, website and team structure, we discussed physics careers. It was good hear the editors’ insights as they cover a broad range of jobs in Physics World and all have a background in physics. It was particularly good to hear from Durrani as he studied chemical physics, which combines my three subjects and my passions.
On Thursday I met David Curry, founder of Quantum Base Alpha – a start-up using quantum-inspired algorithms to solve issues facing humanity. We talked about physics in a business context, what he and his company do, and what he hopes for the future of quantum.
I then gave my presentation on “Why should young people care about quantum?”. I detailed the importance of quantum physics, the major things happening in the field and what it can become, as well as the careers quantum will offer in the future. I also discussed diversity and representation in the physics community, and how that is translated to what I see in everyday life, such as in my school and class. As a woman of colour going into science, technology, engineering and mathematics (STEM), I think it is important for me to have conversations around diversity of both gender and race, and the combination of two. After my presentation, Curry gave me some feedback, and we discussed what I am aiming to do at university and beyond.
For my final day, I visited the University of Sussex, where I toured the campus with Curry’s daughter Kitty, an undergraduate student studying social sciences. I then met up again with Curry, who introduced me to Thomas Clarke, a PhD student in Sussex’s ion quantum technologies group. We went to the physics and maths building, where he explained the simple process of quantum computing to me, and the struggles they have implementing that on a larger scale.
Clarke then gave us a tour of the lab that he shares with other PhD students, and showed us his experiments, which consisted of multiple lasers that made up their trapped ion quantum computing platform. As we read off his oscilloscope attached to the laser system, it was interesting to hear that a lot of his work involved trial and error, and the visit helped me realize that I am probably more interested in the experimental side of physics rather than pure theory.
My work experience week at the IOP has been vital in helping me to understand how physics can be applied in both business and academia. Thanks to the IOP’s involvement in the IYQ, I now have a deeper understanding of quantum science and how it might one day be applied to almost every aspect of physics – including chemical physics – as the sector grows in interest and funding. It’s been an eye-opening week, and I’ve returned to school excited and better informed about my potential next career steps.

Artificial intelligence (AI) holds great potential for a range of data-intensive healthcare tasks: detecting cancer in diagnostic images, segmenting images for adaptive radiotherapy and perhaps one day even fully automating the radiation therapy workflow.
Now, for the first time, a team at Northwestern Medicine in Illinois has integrated a generative AI tool into a live clinical workflow to draft radiology reports on X-ray images. In routine use, the AI model increased documentation efficiency by an average of 15.5%, while maintaining diagnostic accuracy.
Medical images such as X-ray scans play a central role in diagnosing and staging disease. To interpret an X-ray, a patient’s imaging data are typically input into the hospital’s PACS (picture archiving and communication system) and sent to radiology reporting software. The radiologist then reviews and interprets the imaging and clinical data and creates a report to help guide treatment decisions.
To speed up this process, Mozziyar Etemadi and colleagues proposed that generative AI could create a draft report that radiologists could then check and edit, saving them from having to start from scratch. To enable this, the researchers built a generative AI model specifically for radiology at Northwestern, based on historical data from the 12-hospital Northwestern Medicine network.
They then integrated this AI model into the existing radiology clinical workflow, enabling it to receive data from the PACS and generate a draft AI report. Within seconds of image acquisition, this report is available within the reporting software, enabling radiologists to create a final report from the AI-generated draft.
“Radiology is a great fit [for generative AI] because the practice of radiology is inherently generative – radiologists are looking very carefully at images and then generating text to summarize what is in the image,” Etemadi tells Physics World. “This is similar, if not identical, to what generative models like ChatGPT do today. Our [AI model] is unique in that it is far more accurate than ChatGPT for this task, was developed years earlier and is thousands of times less costly.”
The researchers tested their AI model on radiographs obtained at Northwestern hospitals over a five month period, reporting their findings in JAMA Network Open. They first examined the AI model’s impact on documentation efficiency for 23 960 radiographs. Unlike previous AI investigations that only used chest X-rays, this work covered all anatomies, with 18.3% of radiographs from non-chest sites (including the abdomen, pelvis, spine, and upper and lower extremities).
Use of the AI model increased report completion efficiency by 15.5% on average – reducing mean documentation time from 189.2 s to 159.8 s – with some radiologists achieving gains as high as 40%. The researchers note that this corresponds to a time saving of more than 63 h over the five months, representing a reduction from roughly 79 to 67 radiologist shifts.
To assess the quality of the AI-based documentation, they investigated the rate at which addenda (used to rectify reporting errors) were made to the final reports. Addenda were required in 17 model-assisted reports and 16 non-model reports, suggesting that use of AI did not impact the quality of radiograph interpretation.
To further verify this, the team also conducted a peer review analysis – in which a second radiologist rates a report according to how well they agree with its findings and text quality – in 400 chest and 400 non-chest studies, split evenly between AI-assisted and non-assisted reports. The peer review revealed no differences in clinical accuracy or text quality between AI-assisted and non-assisted interpretations, reinforcing the radiologist’s ability to create high-quality documentation using the AI.
Finally, the researchers applied the model to flag unexpected life-threatening pathologies, such as pneumothorax (collapsed lung), using an automated prioritization system that monitors the AI-generated reports. The system exhibited a sensitivity of 72.7% and specificity of 99.9% for detecting unexpected pneumothorax. Importantly, these priority flags were generated between 21 and 45 s after study completion, compared with a median of 24.5 min for radiologist notifications.
Etemadi notes that previous AI systems were designed to detect specific findings and output a “yes” or “no” for each disease type. The team’s new model, on the other hand, creates a full text draft containing detailed comments.
“This precise language can then be searched to make more precise and actionable alerts,” he explains. “For example, we don’t need to know if a patient has a pneumothorax if we already know they have one and it is getting better. This cannot be done with existing systems that just provide a simple yes/no response.”
The team is now working to increase the accuracy of the AI tool, to enable more subtle and rare findings, as well as expand beyond X-ray images. “We currently have CT working and are looking to expand to MRI, ultrasound, mammography, PET and more, as well as modalities beyond radiology like ophthalmology and dermatology,” says Etemadi.
The researchers conclude that their generative AI tool could help alleviate radiologist shortages, with radiologist and AI collaborating to improve clinical care delivery. They emphasize, though, that the technology won’t replace humans. “You still need a radiologist as the gold standard,” says co-author Samir Abboud in a press statement. “Our role becomes ensuring every interpretation is right for the patient.”
