Michel H. Devoret

In 2025, the Nobel Prize in Physics was jointly awarded to Dr. Michel H. Devoret (France), Dr. John M. Martinis (USA), and Dr. John Clarke (UK) for their groundbreaking discoveries of macroscopic quantum mechanical tunneling and energy quantization in superconducting electrical circuits.

Their work proved that quantum behavior — once confined to atoms — can be engineered into large-scale devices, paving the way for quantum computers, superconducting electronics, and the dawn of quantum technology.

Early Life and Education

Michel Henri Devoret was born in Les Andelys, France, in 1954.

Fascinated by physics from a young age, he pursued his studies at École Normale Supérieure (ENS) in Paris, one of France’s most prestigious institutions.

He earned his Ph.D. in Physics from the University of Paris VI (Pierre and Marie Curie University) in 1982 under the mentorship of renowned physicist John Clarke at the University of California, Berkeley — a collaboration that would later come full circle with their shared Nobel Prize.

After postdoctoral work at the Centre National de la Recherche Scientifique (CNRS) in Paris, Devoret became one of the leading figures in mesoscopic physics — the study of systems that bridge the microscopic and macroscopic worlds.

The Discovery — Building Quantum Circuits

The Quantum Frontier

For much of the 20th century, quantum mechanics was considered too delicate to exist outside the atomic realm. But Devoret’s experiments demonstrated otherwise: quantum behavior could be designed, sustained, and controlled in engineered electrical systems.

Quantum Tunneling and Energy Quantization

In the late 1980s and early 1990s, Devoret conducted groundbreaking experiments with superconducting Josephson junctions — devices where electrical current can tunnel through insulating barriers without resistance.

By manipulating these circuits at temperatures near absolute zero, he observed quantum tunneling and discrete energy levels, proving that macroscopic quantum coherence could exist in man-made devices. (source: Nature)

This was revolutionary: it meant that quantum effects could be harnessed for technology, not just observed in isolated particles.

“Quantum mechanics is not confined to the microscopic world — it is a universal language that can be engineered,” said Devoret in an interview following his Nobel announcement. (source: AP)

The Transmon Revolution

One of Devoret’s most influential contributions came in collaboration with Dr. Robert Schoelkopf at Yale University, where they developed the transmon qubit in the mid-2000s.

Unlike earlier qubits that were fragile and prone to noise, the transmon qubit dramatically improved stability and coherence times, making it a cornerstone of modern superconducting quantum computing.

Today, nearly all leading quantum processors — including those by IBM, Google, and Yale Quantum Institute — are based on variations of the transmon architecture. (source: BBC)

“The transmon turned quantum theory into hardware reality,” said Schoelkopf about their collaboration. (source: The Guardian)

The 2025 Nobel Prize — Recognition of Quantum Mastery

The Royal Swedish Academy of Sciences awarded the 2025 Nobel Prize in Physics to Devoret, Clarke, and Martinis for “discovering that quantum mechanics governs not only microscopic particles but also macroscopic systems engineered through superconducting circuits.”

At the Nobel ceremony in Stockholm, Devoret said:

“The quantum world is not a mystery — it’s a reality we can now shape. This is only the beginning of what humanity can do with it.” (source: Reuters)

His words captured the essence of his career — bridging imagination, theory, and experimental precision.
