Nobel Prize in Physics awarded to 3 scientists for quantum mechanical tunnelling

Scientists John Clarke, Michel Devoret and John Martinis won the 2025 Nobel Prize in Physics for "the discovery of macroscopic quantum mechanical tunnelling and energy quantization in an electric circuit," 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," said a statement accompanied by the prize's announcement from Stockholm.

Clarke conducted his research at the University of California-Berkeley, Martinis at the University of California-Santa Barbara; and Devoret at Yale University and also at the University of California-Santa Barbara. Devoret and Martinis have each been affiliated with Google Quantum A.I.
