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 Frontières Quantiques
IRL LFQ,
of the GDR CNRS Physique Mésoscopique (GDR 2426)
and of the GDR CNRS Technologies Quantiques (GDR 2149).
