Three scientists shared the Nobel Prize in physics for demonstrating how quantum mechanics work on a new scale, with potential implications for the next generation of quantum technology.
The winners announced Tuesday are John Clarke of University of California at Berkeley, Michel H. Devoret of Yale University and University of California at Santa Barbara and John M. Martinis of University of California at Santa Barbara.
The award was given “for the discovery of macroscopic quantum mechanical tunneling and energy quantisation in an electric circuit” for experiments conducted in the 1980s that demonstrated the quantum tunneling phenomenon “in a system big enough to be held in the hand.”

These three UC-affiliated scientists shared the 2025 Nobel Prize in Physics for their work in advancing quantum science.
