J.P.G. is grateful to All Souls College, Oxford, for support through a visiting fellowship during the time most of this work was carried out. We derive a general scheme to obtain quantum fluctuation relations for dynamical observables in open quantum systems. For concreteness, we consider Markovian nonunitary dynamics that is unraveled in terms of quantum jump trajectories and exploit techniques from the theory of large deviations like the tilted ensemble and the Doob transform. Our results here generalize to open quantum system fluctuation relations previously obtained for classical Markovian systems and add to the vast literature on fluctuation relations in the quantum domain, but without resorting to the standard two-point measurement scheme. We illustrate our findings with three examples to highlight and discuss the main features of our general result. 2021-09-30T12:22:09Z 2021-09-30T12:22:09Z 2021-07-09 journal article Marcantoni, S., Pérez-Espigares, C., Garrahan, J.
