The Nobel Prize 2025 in Physics was awarded to John Clarke, Michel Devoret and John Martinis

The Nobel Prize 2025 in Physics was awarded to John Clarke, Michel Devoret and John Martinis on Tuesday “for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit".

John Clarke of the University of California, Berkeley, Michel H. Devoret of Yale University and the University of California, Santa Barbara and John M. Martinis of the University of California, Santa Barbara.

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. The Royal Swedish Academy of Sciences said that their experiments “revealed quantum physics in action” using a chip-based electrical circuit, demonstrating that quantum phenomena can manifest on a scale large enough to be held in the hand.

The Nobel Prizes were established through the will of Alfred Nobel, who amassed a fortune from his invention of dynamite. Since 1901, with occasional interruptions, the prizes have annually recognised achievements in science, literature, and peace. Economics was a later addition.
