This work has been partially supported by COST Action MP1209 "Thermodynamics in the Quantum Regime."We analyze the production of entropy along nonequilibrium processes in quantum systems coupled to generic environments. First, we show that the entropy production due to final measurements and the loss of correlations obeys a fluctuation theorem in detailed and integral forms. Second, we discuss the decomposition of the entropy production into two positive contributions, adiabatic and nonadiabatic, based on the existence of invariant states of the local dynamics. Fluctuation theorems for both contributions hold only for evolutions verifying a specific condition of quantum origin. We illustrate our results with three relevant examples of quantum thermodynamic processes far from equilibrium.engjournal articlehttp://dx.doi.org/10.1103/PhysRevX.8.031037https://journals.aps.org/open access539.1Dynamical semigroupsHeat enginesThermodynamicsEquivalentGeneratorsSystemsFísica nuclear2207 Física Atómica y Nuclear
