Rapid mixing and frustration-freeness of short- or long-range Lindbladians imply polynomial (not exponential) decay of CMI and MI of the fixed point; long-range Gibbs states are locally Markovian at any temperature.
Mixing time of Lindblad-governed open quantum systems is determined by the Liouvillian gap plus trace-norm factors of eigenmodes, yielding rapid mixing conditions via sparsity constraints on the Hamiltonian and local Lindblad operators.
Extends KMS-detailed balance constructions from open quantum systems to prepare microcanonical ensembles and other stationary states with criteria for efficient implementation.
A literature review synthesizing developments in quantum Wasserstein distances, their applications, and unresolved questions.
