Abstract

We propose an operational framework to study the nonequilibrium thermodynamics of a quantum system S that is coupled to a detector D whose state is continuously monitored, allowing us to single out individual quantum trajectories of S. We focus on detailed fluctuation theorems and characterize the entropy production of the system. We establish fundamental differences with respect to the thermodynamics of unmonitored, unitarily evolved systems. We consider the paradigmatic example of circuit QED, where superconducting qubits can be coupled to a continuously monitored resonator and show numerical simulations using state-of-the-art experimental parameters.
