2025 Nobel Prize in Physics

Awarded for pioneering experiments that demonstrated macroscopic quantum tunneling and energy quantization in superconducting circuits — the foundation of today's quantum computers.

John Clarke

UC Berkeley

Demonstrated macroscopic quantum tunneling in superconducting circuits and invented the SQUID

British-American physicist. Pioneer of superconducting quantum devices since the 1960s. His invention of the SQUID (Superconducting Quantum Interference Device) remains the most sensitive magnetic-flux detector ever built, enabling applications from brain imaging to gravitational wave detection.

Michel Devoret

Yale University

Proved that electrical circuits can behave quantum-mechanically and demonstrated energy quantization

French-American physicist. In the 1980s-90s, his experiments at CEA-Saclay showed that macroscopic superconducting circuits obey quantum mechanics, exhibiting discrete energy levels just like atoms. This breakthrough established the field of circuit quantum electrodynamics (circuit QED).

John Martinis

UC Santa Barbara

Built the first high-fidelity superconducting qubit and led the 2019 Google quantum supremacy experiment

American physicist. Transformed superconducting circuits from lab curiosities into practical quantum processors. At Google, his team demonstrated quantum supremacy in 2019 — a 53-qubit Sycamore processor solved a problem in 200 seconds that would take classical supercomputers 10,000 years.

Their work proved that a macroscopic electrical circuit — cooled to near absolute zero — can behave like a single quantum particle. This made it possible to engineer artificial atoms from superconducting circuits, which today form the qubits inside quantum computers from Google, IBM, and others. This is the bridge between quantum theory and quantum technology.
