This is an introductory text reviewing Lieb-Robinson bounds for open and closed quantum many-body systems. We introduce the Heisenberg picture for time-dependent local Liouvillians and state a Lieb-Robinson bound that gives rise to a maximum speed of propagation of correlations in many body systems of locally interacting spins and fermions. Finally, we discuss a number of important consequences concerning the simulation of time evolution and properties of ground states and stationary states.

  1. Noise structuring in fixed-depth Trotter simulation: stationary channels and observable-level depolarization

    quant-ph 2026-07 conditional novelty 6.0 of 10

    A fixed-depth Trotter protocol makes hardware noise almost endpoint-independent, producing a stationary binomial/Poisson noise channel and an observable-level affine contrast correction for error mitigation.
