Recorded 12 January 2026. Anthony (Chi-Fang) Chen of the Simons Institute for the Theory of Computing presents "Fast Mixing of 1D Quantum Systems at All Temperatures" at IPAM's New Frontiers in Quantum Algorithms for Open Quantum Systems Workshop. Abstract: It is shown that every one-dimensional Hamiltonian with short-range interaction admits a quantum Gibbs sampler with a system-size independent spectral gap at all finite temperatures. Consequently, their Gibbs states can be prepared in polylogarithmic depth, and satisfy exponential clustering of correlations, generalizing [Ara69].
