Abstract

This work extends Lieb–Robinson bounds to discrete-time quantum dynamics with finite-dimensional memory subsystems on each bond. Exponential bounds on correlation propagation are derived, establishing an effective finite velocity for information spreading in non-Markovian quantum systems.
