Clarke, Devoret and Martinis Win 2025 Nobel Physics Prize for Quantum Tunnelling Experiments

The Nobel committee credited their 1980s circuit studies with laying foundations for superconducting qubits used in today’s quantum technologies.

Overview

  • The Royal Swedish Academy of Sciences named John Clarke, Michel H. Devoret and John M. Martinis as this year’s physics laureates for breakthroughs in quantum tunnelling.
  • Their 1980s experiments created electrical circuits that exhibit quantum behavior when cooled near absolute zero, enabling observations of quantum mechanics on a macroscopic scale.
  • The Nobel committee said the discoveries underpin quantum cryptography, quantum computers and quantum sensors, establishing key groundwork for superconducting qubits used by Google, IBM, Alice & Bob, IQM and Oxford Quantum Circuits.
  • The three scientists will share the 11 million Swedish kronor award.
  • Clarke called the honour “the surprise of my life,” while committee chair Olle Eriksson emphasized the work’s enduring significance and its link to modern digital technology.
