Nobel Prize in Physics Goes to Researchers for Discoveries in Quantum Mechanics

The 2025 Nobel Prize in physics has been awarded to three scientists – a Briton, a Frenchman and an American – for their ground-breaking discoveries in the field of quantum mechanics.

The Nobel Committee announced Tuesday at a ceremony in Stockholm, Sweden, that John Clarke, Michel Devoret and John Martinis will share the prize for the discovery of macroscopic quantum mechanical tunnelling and energy quantization in an electric circuit.

Clarke conducted his research at the University of California, Berkeley; Martinis at the University of California, Santa Barbara; and Devoret at Yale and also at the University of California, Santa Barbara.

Last year, artificial intelligence pioneers John Hopfield and Geoffrey Hinton won the physics prize for helping create the building blocks of machine learning.
