Sommaire:

Progress has been made during the last decades in the development of a statistical theory for classical out-of-equilibrium system. In addition to celebrated fluctuation theorems, stochastic thermodynamic now provides both a nice unifying theoretical framework and a useful way for studying these systems experimentally. This success in understanding classical systems drew interest in similar problems for out-of-equilibrium quantum systems. A set of various fluctuation relations have then been obtained. Severe issues however appeared in the very definition of thermodynamic quantities for quantum systems, and a unified framework for driven out-of-equilibrium quantum open system is not yet available. We propose to fill this gap by constructing a quantum stochastic thermodynamics allowing for definitions of basic thermodynamic quantities such as heat transfer, work and entropy at the single trajectory level. This formalism can then be used to obtained “central” fluctuation theorems, from which follow more practical fluctuation relations such as for instance Jarzynski and Crooks fluctuation theorems.
