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.





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).
