Quantum trio win Nobel for groundbreaking work

John Clarke, Michel Devoret, and John Martinis won the $1.17 million Nobel Prize for pioneering macroscopic quantum tunnelling with superconductors.

  • The Royal Swedish Academy of Sciences awarded the 2025 Nobel Prize in Physics 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, sharing the $1.17M prize announced in Stockholm.
  • In the 1980s, the team demonstrated quantum tunnelling on a macroscopic scale using Josephson junctions and macroscopic superconducting circuits.
  • They observed both macroscopic quantum mechanical tunnelling and discrete energy levels after cooling the circuit, opening the door to quantum cryptography, quantum computers, and quantum sensors.
  • The laureates will receive their prizes on December 10, and the 11-million Swedish kronor will be shared equally; the physics prize follows Monday's medicine award.
  • Olle Eriksson said the work underpins digital technology, and subsequent research in the 1990s and 2000s developed superconducting qubits, positioning these circuits at the heart of quantum technologies.

This year's Nobel Prize in Physics goes to Briton John Clarke, American John Martinis, and Frenchman Michel Devoret. The Nobel Prize Committee announced in Stockholm, Sweden, that they will receive the prize for their groundbreaking research in quantum mechanics. Physicist Richard Feynman once said of this field of research that if you think you understand quantum mechanics, you don't quite understand it. Materials can behave completely counteri…
