Classical and Quantum Tensor Product Expanders
M. B. Hastings, A. W. Harrow
We introduce the concept of quantum tensor product expanders. These are expanders that act on several copies of a given system, where the Kraus operators are tensor products of the…

Observations Outside the Light-Cone: Algorithms for Non-Equilibrium and Thermal States
M. B. Hastings
We apply algorithms based on Lieb-Robinson bounds to simulate time-dependent and thermal quantities in quantum systems. For time-dependent systems, we modify a previous mapping to…
