Abstract: The task of finding computationally more tractable descriptions of quantum dynamical systems is of paramount importance for tasks ranging from many-body quantum simulation to control. In this talk, I will present a recently proposed method to construct reduced-order models that exactly reproduce the evolution of selected observables or initial states of a Markovian quantum system of interest. The proposed framework leverages results from control-systems theory as well as classical and quantum probability and is strongly tied to symmetry notions in quantum dynamical systems. This framework is very general and has been applied to the reduction of both discrete- and continuous- time quantum dynamics and quantum trajectories. Notably, for systems evolving under Lindblad dynamics, our approach yields a reduced quantum-dynamical generator that is still in Lindblad form. Examples will be presented, including decoherence dynamics in central-spin systems coupled to structured environments and continuously monitored spin chains.
