Simultaneous determination of multiple low-lying energy levels on a superconducting quantum processor
Huili Zhang, Yibin Guo, Guanglei Xu +4
Determining the ground and low-lying excited states is critical in numerous scenarios. Recent work has proposed the ancilla-entangled variational quantum eigensolver (AEVQE) that u…

Simultaneous determination of multiple low-energy eigenstates of many-body systems on a superconducting quantum processor
Huili Zhang, Yibin Guo, Guanglei Xu +4
The determination of the ground and low-lying excited states is critical in many studies of quantum chemistry and condensed-matter physics. Recent theoretical work proposes a varia…
