The 2025 Nobel Prize in Physics is awarded to John Clarke, Michel H. Devoret and John M. Martinis “for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit”

Their experiments 'demonstrated that quantum mechanical properties can be made concrete on a macroscopic scale'. They physicists work could 'also demonstrate that the system behaves in the manner predicted by quantum mechanics – it is quantised, meaning that it only absorbs or emits specific amounts of energy.'

John Clarke (born 1942, UK) holds a PhD from the University of Cambridge and is a Professor at the University of California.

Michel H. Devoret (born 1953, France) holds a PhD from Paris-Sud University, France. He is a Professor at Yale University and the University of California.

John M. Martinis (born 1958, USA) holds a PhD from the University of California where he is also a Professor.

The laureates will share the prize amout of 11 million Swedish kronor, equally.
