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…

Sample complexity of matrix product states at finite temperature
Atsushi Iwaki, Chisa Hotta
For quantum many-body systems in one dimension, computational complexity theory reveals that the evaluation of ground-state energy remains elusive on quantum computers, contrasting…

Purity of thermal mixed quantum states
Atsushi Iwaki, Chisa Hotta
We develop a formula to evaluate the purity of a series of thermal equilibrium states that can be calculated in numerical experiments without knowing the exact form of the quantum…
