Michel Henri Devoret[5] (French pronunciation: [miʃɛl dəvɔʁɛ]; born 1953) is a French-American physicist. He is Professor of Physics at the University of California, Santa Barbara,[6][7] and Professor Emeritus of Applied Physics at Yale University.[8] He holds the title of Chief Scientist of Quantum Hardware at Google Quantum AI.[9] He is known for the development of various superconducting quantum computing architectures, including the quantronium, the transmon, and the fluxonium. He also developed microwave quantum limited amplifier for qubit readout and sensing.[10]

He shared the 2025 Nobel Prize in Physics with John Clarke and John M. Martinis for their joint work on macroscopic quantum phenomena in superconducting circuits.[11]

Early life and education

[edit]

Devoret was born in Paris, France, in 1953.[12][13]

Devoret graduated as a telecommunications engineer from École nationale supérieure des télécommunications in Paris in 1975.[14][12] He obtained a graduate diploma (DEA) in quantum optics from the University of Orsay (present-day Paris-Saclay University), followed by a doctorate in condensed matter physics in 1982.[12][14] He performed his doctorate work at CEA Saclay in the group of Anatole Abragam.[15][16] His doctoral supervisor was Neil S. Sullivan.[16]

Career

[edit]

Devoret worked as a postdoctoral researcher in John Clarke's group at the University of California, Berkeley, from 1982 to 1984.[12] Together, with John M. Martinis, a graduate student at the time, they demonstrated for the first time the mesoscopic quantum levels of a Josephson junction in 1985.[12][17]

Devoret then returned to France and founded the Quantronics group at the Orme des Merisiers laboratory of CEA Saclay together with Daniel Esteve [fr] and Cristian Urbina. The group measured the traversal time of tunnelling, invented an electron pump, observed the charge of Cooper pairs directly, and developed a type of qubit dubbed quantronium. They also observed the Ramsey fringes of quantronium.[12][18][19]

Devoret became a professor at Yale University in 2002. In Yale, Steven Girvin, Robert J. Schoelkopf and Devoret devised a type of superconducting charge qubit called the transmon.[20][21] In 2009, Devoret also pioneered fluxonium[22], which can be understood as a special type of flux qubit.

He was appointed to the Collège de France in 2007 and resigned in 2013.[12][18]

In 2023, he became the Chief Scientist for Hardware at Google Quantum AI.[9] He was appointed, in 2024, Professor of Physics at University of California, Santa Barbara.[6]

He discusses his education and career in an interview with historian of science David Zierler, available at the Niels Bohr Library & Archives.[23]

Honors and awards

[edit]

In 2013 Devoret was awarded with Schoelkopf the John Stewart Bell Prize for "Fundamental and pioneering experimental advances in entangling superconducting qubits and microwave photons, and their application to quantum information processing."[24]

In 2014, he shared the Fritz London Memorial Prize with Martinis and Schoelkopf.[25]

In 2021, the Micius Quantum Prize was jointly awarded to Devoret, Clarke and Yasunobu Nakamura.[26]

In 2025 Devoret, Clarke and Martinis were awarded the Nobel Prize in Physics for their joint discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.[11]
