John Clarke, Michel Devoret & John Martinis Won 2025 Nobel Prize in Physics

Current Context: The 2025 Nobel Prize in Physics was awarded on 7 October 2025 to John Clarke, Michel H. Devoret, and John M. Martinis.

• They were honoured “for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.”
• Their pioneering experiments in the 1980s with superconducting circuits and Josephson junctions proved that entire circuits can behave as quantum systems.
• This breakthrough laid the scientific foundation for superconducting qubits, central to today’s quantum computers.
• The prize, worth 11 million Swedish kronor, will be presented on 10 December 2025 in Stockholm.
