Quantum many-body simulation of finite-temperature systems with sampling a series expansion of a quantum imaginary-time evolution

Norifumi Matsumoto, Shoichiro Tsutsui, Yuya O. Nakagawa +5

Simulating thermal-equilibrium properties at finite temperature is crucial for studying quantum many-body systems. Quantum computers are expected to enable us to simulate large sys…

Practical quantum advantage on partially fault-tolerant quantum computer

Riki Toshio, Yutaro Akahoshi, Jun Fujisaki +3

Achieving quantum speedups in practical tasks remains challenging for current noisy intermediate-scale quantum (NISQ) devices. These devices always encounter significant obstacles…
