Quantum Circuit Group

QUANTUM CIRCUIT GROUP

Ecole Normale Supérieure de Lyon

Our research group explores the physics of information in quantum devices, which we design, realize and measure. These objects can be viewed as quantum machines processing information. In contrast with ordinary devices, in which quantum mechanics enters only at the level of individual electrons, the degrees of freedom of these machines at the signal level behave according to the laws of quantum mechanics.
Topics of our current interest include amplification of quantum signals, electron spin resonance at the nanoscale, quantum feedback and trajectory, thermodynamics of quantum information, microwave quantum optics, quantum error correction and quantum measurement.
The Quantum Circuit group was funded in 2016 when Benjamin Huard became professor in Ecole Normale Supérieure of Lyon, therefore leaving the Quantum Electronics Group he cofunded in 2008 with Michel Devoret at Ecole Normale Supérieure of Paris. Audrey Bienfait joined the group late in 2019 as a CNRS researcher.

We are looking for post-docs, to work on experiments if you're interested!

Our group is a member of the Laboratoire International Associé Laboratoire sur les Circuits et Matériaux Quantiques (LIA LCMQ), of the Groupement de Recherche du CNRS Physique Mésoscopique (GDR 2426) and of the Groupement de Recherche du CNRS Information Quantique (GDR 3322).

MEMBERS

FACULTY

Audrey Bienfait

Audrey completed her Ph.D. in the Quantronics group at CEA Saclay (France) in 2016. There, she worked with Patrice Bertet on coupling bismuth donor spins to high quality factor small-mode-volume superconducting resonators. The experiments applied circuit quantum electrodynamics techniques to electron spin resonance and improved the spin signal detection sensitivity and implemented a spin initialization mechanism via the Purcell effect. She then realized a post-doc in the Cleland group at the University of Chicago (USA), where she coupled remote superconducting qubits using traveling phonons and realized acoustic interferometry experiments. In 2019, she joined the Quantum Circuit group as a CNRS researcher. She received the Bruker thesis prize and a Paris-Saclay university award for her graduate research work. Her current research interests are electronic spins, superconducting circuits, and various microwave transduction schemes. Publication list.

Benjamin Huard

Benjamin Huard graduated from the Ecole Normale Supérieure of Paris in 2003 and did his PhD studies in the Quantronics group at CEA Saclay (France) with Hugues Pothier. There, he performed experiments aiming at investigating the behavior of electrons in mesoscopic metallic and superconducting conductors. In 2006, he joined the Goldhaber-Gordon group at Stanford University (USA) as a post-doc fellow, and observed the Klein tunneling of electrons in graphene for the first time. In 2008, as a CNRS researcher, he cofounded the Quantum Electronics group at Ecole Normale Supérieure (Paris, France) with Michel Devoret. Since then, he worked on superconducting circuits in which he worked on quantum measurement and feedback, thermodynamics of quantum information, microwave quantum optics. He is now a professor at Ecole Normale Supérieure de Lyon where he moved in 2017 and leads the Quantum Circuit Group together with Audrey Bienfait. He is a scientific adviser of the Alice and Bob company since 2021. Publication list
