STOCKHOLM, Oct 7 (Reuters) - 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", the award-giving body said on Tuesday. "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 prize-awarding body said in a statement.
The laureates carried out experiments with an electrical circuit in which they demonstrated both quantum mechanical tunnelling and quantised energy levels in a system big enough to be held in the hand, the Royal Swedish Academy of Sciences said in a statement.
"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.
British-born Clarke is a professor at the University of California, Berkeley, in the United States. Devoret, born in France, is a professor at Yale University and the University of California, Santa Barbara, also in the United States, where Martinis is also a professor.
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.
