The 2025 Nobel Prize in Physics has been awarded to John Clarke, Michel H. Devoret and John M. Martinis for research that helped make quantum phenomena tangible in an electrical circuit, according to Euronews’ report on the announcement.
The prize recognizes work from the 1980s that showed how quantum mechanics can be observed in systems built from superconductors. The trio’s experiments demonstrated that electrical current could tunnel from one state to another and that energy could be absorbed and emitted in specific quantities, matching the predictions of quantum theory. In other words, they studied a system large enough to be engineered and measured, yet still governed by the strange rules normally associated with atoms and subatomic particles.
That distinction is what gives the award its wider significance. Quantum mechanics is foundational to modern digital technology, and the report explicitly links it to smartphones, computers, lasers and MRI scanners. The Nobel Committee’s choice therefore connects abstract physics to the hardware and medical tools people use every day.
The laureates themselves are drawn from institutions in the United States. Clarke is a professor emeritus at the University of California, Berkeley. Devoret is a professor emeritus of applied physics at Yale University and was born in France. Martinis is an American professor emeritus at the University of California, Santa Barbara. Euronews reported that Clarke reacted to the news on a call from Sweden and said he was stunned by the award.
The announcement also arrived early in the Nobel season. Euronews said the physics award was the second Nobel Prize of 2025 to be announced that week, with more prizes to follow in chemistry, literature and peace. The economics prize was scheduled later in the month, and the laureates were to receive their medals and diplomas in Sweden in December.
The award carries a cash prize of 11 million Swedish kronor. Beyond the money, the more important consequence is the recognition of a line of research that helped establish how quantum systems can be controlled and studied in practice. The experiments are decades old, but the committee’s decision suggests their influence on current science and technology remains central.
The Nobel Prize in Physics has been awarded since 1901, and Euronews noted that 118 physics Nobel Prizes had been awarded from 1901 through 2024. The report also said that five of the 227 physics winners had been women, including Marie Curie in 1903. Those figures put the 2025 prize into a long historical sequence, one in which a handful of discoveries become part of the standard architecture of modern science.
This year’s physics award is therefore both retrospective and forward-looking: a recognition of work done in the 1980s and a reminder that quantum mechanics still underpins the digital world.
The prize is also a reminder that some of the most consequential physics work begins as experiments that look narrow at the time. Decades later, those results become the language through which new devices are built and measured. That is why the Nobel committee keeps returning to foundational research: it often turns out to be the scaffolding for an entire technological era.
