A general approach to obtain reduced models for a wide class of discrete-time quantum
systems is proposed. The obtained models not only reproduce exactly the output of a given …

Exact Model Reduction for Continuous-Time Open Quantum Dynamics
We consider finite-dimensional many-body quantum systems described by time-
independent Hamiltonians and Markovian master equations, and present a systematic …
