Detecting quantum phase transitions via shallow variational quantum circuits
Ching-Yu Huang, Min-Fong Yang
Mapping quantum phase diagrams through classical simulation is notoriously resource-intensive, as even small systems far from the thermodynamic limit demand prohibitive computation…

Mitigating the sign problem by quantum computing
Kwai-Kong Ng, Min-Fong Yang
The notorious sign problem severely limits the applicability of quantum Monte Carlo (QMC) simulations, as statistical errors grow exponentially with system size and inverse tempera…
