Quantum Error Suppression via Symmetry-Averaged Virtual Distillation
Canyu He, Chunhua Zeng, Ruyu Yang +1
Reliable quantum simulation is limited by both algorithmic approximations and hardware noise, which usually coexist in the output of near-term and early fault-tolerant quantum devi…

Quantum-enhanced Green's function Monte Carlo for excited states of nuclear shell model
Yongdan Yang, Ruyu Yang, Xiaosi Xu
We present a hybrid quantum-classical Green's function Monte Carlo (GFMC) algorithm for estimating the excited states of the nuclear shell model. The conventional GFMC method, wide…
