STOCKHOLM: U.S.-based scientists John Clarke, Michel Devoret and John Martinis won the 2025 Nobel Prize in Physics for “experiments that revealed quantum physics in action”, paving the way for the development of the next generation of digital technologies.
“My feelings are that I’m completely stunned. Of course it had never occurred to me in any way that this might be the basis of a Nobel Prize,” Clarke told the Nobel press conference by telephone on Tuesday.
“I’m speaking on my cell phone and I suspect that you are too, and one of the underlying reasons that the cell phone works is because of all this work.”
‘NEW SURPRISES’ IN CENTURY-OLD FIELD OF QUANTUM MECHANICS
Quantum mechanical behaviours are well studied at the level of the incredibly small – atoms and sub-atomic particles – but are often seen as bizarre and unintuitive compared with classical physics and its far larger scale.
The Nobel winners carried out experiments in the mid-1980s with an electronic circuit built of superconductors and demonstrated that quantum mechanics could also influence everyday objects under certain conditions.
“It is wonderful to be able to celebrate the way that century-old quantum mechanics continually offers new surprises. It is also enormously useful, as quantum mechanics is the foundation of all digital technology,” Olle Eriksson, chair of the Nobel Committee for Physics, said.
Quantum technology is already ubiquitous, with transistors in computer microchips an everyday example.
“This year’s Nobel Prize in Physics has provided opportunities for developing the next generation of quantum technology, including quantum cryptography, quantum computers, and quantum sensors,” the Royal Swedish Academy of Sciences, which awards the prize, said in a statement.
Quantum computers use principles of quantum mechanics to make complex calculations, predict outcomes and perform analysis that in some cases could take traditional computers millions of years.
The field is considered to have the potential to help solve some of humanity’s most pressing concerns, such as tackling climate change. But it also faces challenges, including improving the accuracy of its chips, and timelines for commercially viable quantum computing remain disputed.
British-born Clarke is a professor at the University of California, Berkeley, in the United States.
Devoret, who was born in France and was congratulated on X by French President Emmanuel Macron, is a professor at Yale University and the University of California, Santa Barbara, also in the United States, where Martinis is also a professor.
Martinis, an American, headed Google’s Quantum Artificial Intelligence Lab until 2020. At Google, Martinis was part of the research team who in 2019 said they had achieved “quantum supremacy”, in which a computer harnessing the properties of sub-atomic particles did a far better job of solving a problem than the world’s most powerful supercomputer.
Devoret, besides his professorship, is also the chief scientist of Google Quantum AI. It is the second straight year that a Nobel has been won by scientists with Google ties. The 2024 chemistry prize was awarded to Demis Hassabis and John Jumper at Google DeepMind while Geoffrey Hinton, who worked for Google for more than a decade, won for physics the same year.
PHYSICS SECOND NOBEL PRIZE AWARDED THIS WEEK
The Nobel physics prize is awarded by the Royal Swedish Academy of Sciences and includes a prize sum totalling 11 million Swedish crowns ($1.2 million) that is shared among the winners if there are several, as is often the case.
The Nobel Prizes were established through the will of Alfred Nobel, who amassed a fortune from his invention of dynamite. Since 1901, with occasional interruptions, the prizes have annually recognised achievements in science, literature, and peace. Economics was a later addition.
Physics was the first category mentioned in Nobel’s will, likely reflecting the prominence of the field during his time. Today, the Nobel Prize in Physics remains widely regarded as the most prestigious award in the discipline.
Past winners of the Nobel physics prize include some of the most influential figures in the history of science, such as Albert Einstein, Erwin Schrodinger, Max Planck and Niels Bohr, the latter three all pioneers of quantum theory.
In keeping with tradition, physics is the second Nobel to be awarded this week, after two American and one Japanese scientist won the medicine prize for breakthroughs in understanding the immune system. The chemistry prize is due next, on Wednesday.
The science, literature and economics prizes are presented to the laureates by the Swedish king at a ceremony in Stockholm on December 10, the anniversary of Alfred Nobel’s death, followed by a lavish banquet at city hall.
The peace prize, which will be announced on Friday, is awarded in a separate ceremony in Oslo.
