The state of an open quantum system undergoing an adiabatic process evolves by following the instantaneous stationary state of its time-dependent dynamical generator. This observation allows one to completely characterize, for generic adiabatic evolutions, the (average) master equation dynamics of the system. However, it does not provide information about the behavior of the system in single dynamical realizations, or single experimental runs. As a consequence, our understanding of full counting statistics of interesting quantities, such as the number of photons emitted by a slowly-driven optical system or the time-integrated stochastic entropy production in an adiabatic machine, remains rather limited. Here, we make progress in this direction and derive the full counting statistics of emission-related observables in generic adiabatic open quantum dynamics. We further compute the probability associated with any possible trajectory of the observable and devise a dynamics which can realize it as its typical behavior. Our findings provide a way to characterize and engineer adiabatic open quantum dynamics as well as to fully control their fluctuating behavior.
