The Nobel Prize in Physics 2025 was awarded jointly to John Clarke (University of California, Berkeley), Michel H. Devoret (Yale University) and John M. Martinis (University of California, Santa Barbara) 'for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit'. In 1984–85, the three laureates conducted experiments with a superconducting electrical circuit held in the hand, demonstrating that quantum mechanical effects could manifest at the macroscopic scale. Their foundational work proved critical to the development of quantum computers — devices with the potential to solve computational problems impossible for today's classical computers. The announcement came on October 7, 2025, just a day before the IMC 2025 inauguration where quantum communications was a central theme.
