## Yale's Devoret Honored for Cutting-Edge Work in Quantum Physics

March 8, 2022

The following news release was originally issued by Yale University. Michel Devoret, a Principal Investigator in Co-design Center for Quantum Advantage (C^{2}QA), leads subthrust 2.3 Quantum Error Correction whose challenge goal is to “Extend the lifetime of quantum information to 10x beyond the lifetime of the constituent elements”. C^{2}QA is one of five Department of Energy Quantum Information Science Research Centers established in support of the National Quantum Initiative. The U.S. Department of Energy’s Brookhaven National Laboratory is the lead institution for C^{2}QA.

Michel Devoret, the F.W. Beinecke Professor of Applied Physics and Physics, is a co-recipient of the Micius Quantum Prize for his groundbreaking work in quantum physics — including key contributions in the development of the artificial atoms of quantum information known as qubits.

The Micius Quantum Prize, awarded since 2018, honors significant advances in quantum science ranging from early conceptual contributions to recent experimental breakthroughs. Named for the ancient Chinese philosopher Mozi, the prize was established with donations from private entrepreneurs.

Devoret shares the prize with John Clarke of the University of California-Berkeley and Yasunobu Nakamura of the University of Tokyo.

Devoret did some of the seminal work on artificial atom design in the mid-1980s, working in Clarke’s lab. He later returned to his native France in the late 1980s, starting his own research group at the Commissariat à l’Energie Atomique (CEA) at Saclay, where he continued his fundamental research on quantum mechanical electronics and qubits with Daniel Esteve and Cristian Urbina.

He joined the Yale faculty in 2002.

At Yale, working with colleagues including Robert Schoelkopf and Steven Girvin, Devoret has dramatically advanced the field of superconducting qubits with controllable dynamics. A qubit is a unit of quantum information. Unlike information in the “classical” state, which can be either a zero or a one, information in the quantum state can be a zero, a one, or a superposition of both zero and one.

Devoret and Schoelkopf are considered the undisputed leaders in the experimental development of circuit quantum electrodynamics (circuit QED), in which the concepts of quantum optics have been brought to bear on superconducting microwave electrical circuits.

“Michel Devoret is a pioneer and international leader in the development of ‘artificial atoms’ created using superconducting electrical circuits,” said Girvin, the Eugene Higgins Professor of Physics at Yale.

“Michel’s foundational research has helped launch a new revolution in quantum mechanics,” Girvin added. “The Micius Quantum Prize is a wonderful recognition of the contributions that he and his co-recipients have made to both fundamental and applied quantum science and engineering.”

Devoret is a member of the American Academy of Arts and Sciences and the French Academy of Sciences. He is the recipient of the Ampere Prize of the French Academy of Science (together with Daniel Esteve), the Descartes-Huygens Prize of the Royal Academy of Science of the Netherlands, and the Europhysics-Agilent Prize of the European Physical Society (with Daniel Esteve, Hans Mooij, and Yasunobu Nakamura). He was awarded the Olli Lounasmaa Memorial Prize of Aalto University.

Devoret is also a recipient of the John Stewart Bell Prize, which he received jointly with Schoelkopf, and the Fritz London Memorial Prize, which he won together with John Martinis and Schoelkopf.

Devoret is a member of the Yale Quantum Institute and leads the devices sub-group on quantum error correction for the Co-design Center for Quantum Advantage (C^{2}QA) led by Brookhaven National Laboratory.

Recipients of the Micius Quantum Prize are awarded one million Chinese yuan (about $150,000) and a gold medal.

“This is richly deserved and a testament to the excellence of Prof. Devoret’s research,” said Vidvuds Ozolins, the Tom Steyer and Kat Taylor Professor of Clean Energy Solutions and chair of the Department of Applied Physics at Yale. “He has been a wonderful mentor to his students and postdoctoral associates. We are honored to have him on our faculty and we are looking forward to strengthening and investing in quantum research at Yale.”
