Markov-Shielded Typicality for Thermal Quantum States
Atsushi Iwaki, Chisa Hotta
Pure states of quantum many-body systems at thermal equilibrium are known to be typical, in a sense that a randomly chosen pure state from an appropriate energy shell reproduces th…

Polylog-depth Quantum Thermal Simulation via Local Recovery Channels
Hideaki Hakoshima, Atsushi Iwaki, Nobuyuki Yoshioka
We establish sufficient conditions for preparing quantum thermal states of noncommuting local Hamiltonians with polylogarithmic circuit depth in arbitrary fixed spatial dimension.…
