- Abstract: The thermodynamics of quantum systems driven out of equilibrium has attracted
increasing attention in last the decade, in connection with quantum information
and statistical physics, and with a focus on non-classical signatures. While a
first approach can deal with average thermodynamics quantities over ensembles,
in order to establish the impact of quantum and environmental fluctuations
during the evolution, a continuous quantum measurement of the open system is
required. Here we provide an introduction to the general theoretical framework
to establish and interpret thermodynamics for quantum systems whose
nonequilibrium evolution is continuously monitored. We review the formalism of
quantum trajectories and its consistent application to the thermodynamic
scenario, where main quantities such as work, heat, and entropy production can
be defined at the stochastic level. The connection to irreversibility and
fluctuation theorems is also discussed, together with some recent developments,
and we provide some simple examples to illustrate the general theoretical
framework.
