Low-variance estimators overcome the phase-gradient bottleneck in complex-valued neural quantum states
Yi-Ran Xue, Rui Wang, Baigeng Wang +1
Complex neural quantum states are difficult to optimize when their wavefunction phase carries gauge, chiral, fermionic, or topological structure. We show that the major failure mod…

Artificial Gauge Field Engineered Excited-State Topology: Control of Dynamical Evolution of Localized Spinons
Jie Ren, Yi-Ran Xue, Run-Jia Luo +2
Spinons are elementary excitations at the core of frustrated quantum magnets. Although it is well-established that a pair of spinons can emerge from a magnon via deconfinement, con…

Neural network-based prediction of the secret-key rate of quantum key distribution
Min-Gang Zhou, Zhi-Ping Liu, Wen-Bo Liu +6
Numerical methods are widely used to calculate the secure key rate of many quantum key distribution protocols in practice, but they consume many computing resources and are too tim…
