Michel Devoret

Michel Henri Devoret (* 1953 ) is a French experimental solid-state physicist who develops nanodevices for quantum information theory ( quantum computers ).

Life

Devoret studied at the École Nationale Superiéure des Telecommunications in Paris with a degree in 1975 and received his doctorate in 1982 from the University of Paris-South in Orsay . For the dissertation he worked at the laboratory of Anatole Abragam at the research center of the CEA in Saclay on NMR in solid hydrogen. As a post-doctoral student , he worked on macroscopic quantum tunneling in John Clarke's laboratory at the University of California, Berkeley . After two years he returned to France and had his own research group with Daniel Estève and Cristian Urbina in Saclay, which dealt with quantum effects in electronics at the mesoscopic level ( called Quantronic by them ). The field is also called circuit quantum electrodynamics and he is one of the pioneers in it with Robert J. Schoelkopf .

In Saclay he and his group measured the tunneling time, invented a one-electron pump (which later provided the basis for a new method of measuring capacitance) and was the first to demonstrate the effect of the valences of atoms on the transport of a single electron and the first observation by Ramsey-Fringes on artificial superconducting atoms (called quantronium by them).

He became research director at the CEA in Saclay and was professor at the Collège de France from 2007 to 2012 . From 2002 he was at Yale University , where he is FW Beincke Professor of Applied Physics and Director of the Applied Physics Nanofabrication Lab.

At Yale, he is continuing his research on electronic devices based on quantum effects in the nano range, based on Josephson junctions of superconductors with applications to possible quantum computers . In 2007, he and Schoelkopf and Steven M. Girvin coupled two superconducting qubits via a quantum bus . Among other things, he researches fault-tolerant quantum memories and remote quantum entanglement.

In 2007 he became a member of the Academie des Sciences (2008), whose Prix ​​Ampère he received with Daniel Estève in 1991, and of the American Academy of Arts and Sciences (2003). In 1996 he received the Descartes Huyghens Prize from the Dutch Academy of Sciences. In 2004 he received the Europhysics-Agilent Prize of the European Physical Society with Daniel Estève, Hans Mooij and Yasunobu Nakamura . In 2014 he received the Fritz London Memorial Prize with Robert Schoelkopf and John Martinis and in 2013 the John Stewart Bell Prize with Schoelkopf . In 2016 he received the Olli V. Loounasma Award from Aalto University in Finland.
