Symmetry restoration and quantum Mpemba effect in symmetric random circuits
Shuo Liu, Hao-Kai Zhang, Shuai Yin +1
Entanglement asymmetry, which serves as a diagnostic tool for symmetry breaking and a proxy for thermalization, has recently been proposed and studied in the context of symmetry re…

Absence of barren plateaus in finite local-depth circuits with long-range entanglement
Hao-Kai Zhang, Shuo Liu, Shi-Xin Zhang
Ground state preparation is classically intractable for general Hamiltonians. On quantum devices, shallow parameterized circuits can be effectively trained to obtain short-range en…
