Nobel Prize in Physics awarded to three physicists from US

New Delhi, Oct. 7 -- Nobel Prize for Physics 2025 has been awarded to three US physicists for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit, the Nobel Committee announced today.

The three are John Clarke of the University of California, Berkeley, Michel H. Devoret of Yale University, New Haven, and University of California, and John M. Martinis of the University of California, the Royal Swedish Academy of Sciences said in a statement.

''Their experiments on a chip revealed quantum physics in action,'' the statement said.

A major question in physics is the maximum size of a system that can demonstrate quantum mechanical effects. This year's Nobel Prize laureates conducted experim...
