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…
Mitigating barren plateaus of variational quantum eigensolvers
Xia Liu, Geng Liu, Jiaxin Huang +2
Variational quantum algorithms (VQAs) are expected to establish valuable applications on near-term quantum computers. However, recent works have pointed out that the performance of…
Fundamental limitations on optimization in variational quantum algorithms
Hao-Kai Zhang, Chengkai Zhu, Geng Liu +1
Exploring quantum applications of near-term quantum devices is a rapidly growing field of quantum information science with both theoretical and practical interests. A leading parad…
