Philippe Campagne-Ibarcq

Philippe graduated from the Ecole Polytechnique in 2011. He obtained his PhD in 2015 in the physics department of ENS Paris, under the supervision of Benjamin Huard. There, he performed several experiments investigating quantum backaction and feedback in superconducting qubits. After a post-doc in the Quantronics group (CEA Saclay) focusing on quantum-enhanced detection of spins in semi-conductors, he joined the group of Michel Devoret at Yale university where he conducted projects leading to deterministic entanglement of remote superconducting circuits and quantum error correction on a ”grid state” logical qubit in a microwave cavity. He joined the Quantic team in 2019 to work on theoretical and experimental aspects of quantum error correction, and in particular autonomous stabilization of logical qubits encoded in high-impedance superconducting circuits.

Zaki Leghtas

Zaki was born in Agadir, Morocco. After graduating from high school in Rabat (Morocco), he moved to France where he spent two years near Nice. He then attended the Ecole des Mines, in Paris, for three years, and graduated in 2009. Zaki enrolled in a PhD program at INRIA/Mines under the supervision of Pierre Rouchon and Mazyar Mirrahimi, where he worked on some theoretical aspects of quantum state preparation and stabilization. After he defended his thesis in 2012, he joined the Devoret lab at Yale University and realized experiments on quantum error correction and quantum feedback. He became a member of the Quantic team in December 2015 as a researcher of MinesParisTech. Publication list

Mazyar Mirrahimi

Mazyar Mirrahimi graduated from Ecole Polytechnique with a major in applied mathematics in 2003. He did his PhD studies with Pierre Rouchon at Ecole des Mines (Paris) from 2003 to 2005 and worked on control and estimation for Schrödinger type equations. After a short visit to Hideo Mabuchi's lab at Caltech, he was hired as a research scientist at INRIA Paris-Rocquencourt in 2006. After spending some years working on theoretical problems related to quantum measurement and feedback, he contributed to the experimental realization of a quantum feedback loop by the group of Serge Haroche at Ecole Normale Supérieure de Paris. From 2011 to 2013, he spent two years as a sabbatical visitor at Yale University collaborating with the teams of Michel Devoret and Robert Schoelkopf. Through these collaborations, he has contirbuted to the design and analysis of various experiments on quantum measurement, feedback, error correction and reserevoir engineering with quantum superconducting circuits. He is currently director of research at INRIA, part-time professor of Ecole Polytechnique, leader of Quantic team, and visiting research scientist at Yale. In 2017, he received the ``Prix Jeune Chercheur d'Inria-Academie des Sciences''. Website
