Michel Devoret
Michel Henri Devoret (French pronunciation: [miʃɛl dəvɔʁɛ]; born 5 March 1953) is a French-American physicist. He is Professor of Physics at the University of California, Santa Barbara, and Professor Emeritus of Applied Physics at Yale University. He serves as the Chief Scientist for Quantum Hardware at Google Quantum AI. He is known for the development of various superconducting quantum computing architectures, including the quantronium, the transmon, and the fluxonium.
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.
Devoret was born in Paris, France, in 1953. He has stated that his parents were of Jewish background, even though they were not religious.
Devoret graduated with an engineer's degree in telecommunications from École nationale supérieure des télécommunications (ENST, now known as Télécom Paris) in Paris in 1975. 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. He performed his doctoral research at CEA Saclay in the group of Anatole Abragam, under the supervision of Neil S. Sullivan.
Devoret worked as a postdoctoral researcher in John Clarke's group at the University of California, Berkeley, from 1982 to 1984. Together, with John M. Martinis, a graduate student at the time, they demonstrated for the first time the quantized energy levels of a Josephson junction in 1985.
Devoret then returned to France and founded the Quantronics group at the Orme des Merisiers laboratory of CEA Saclay together with Daniel Esteve 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.
In 1996, Devoret spent a research stay in the laboratory of Hans Mooij at Delft University of Technology.
Devoret became a professor at Yale University in 2002. At Yale University, Steven Girvin, Robert J. Schoelkopf, and Devoret devised a type of superconducting charge qubit called the transmon. In 2009, Devoret also pioneered fluxonium, which can be understood as a special type of flux qubit. In 2010, he also developed a microwave quantum limited amplifier for qubit readout and sensing.
