Hybrid quantum-classical algorithms for solving quantum chemistry in Hamiltonian-wavefunction space
Zhan-Hao Yuan, Tao Yin, Dan-Bo Zhang
Variational quantum eigensolver~(VQE) typically optimizes variational parameters in a quantum circuit to prepare eigenstates for a quantum system. Its applications to many problems…

Variational quantum eigensolvers by variance minimization
Dan-Bo Zhang, Zhan-Hao Yuan, Tao Yin
Variational quantum eigensolver(VQE) typically minimizes energy with hybrid quantum-classical optimization, which aims to find the ground state. Here, we propose a VQE by minimizin…

Collective optimization for variational quantum eigensolvers
Dan-Bo Zhang, Tao Yin
Variational quantum eigensolver (VQE) optimizes parameterized eigenstates of a Hamiltonian on a quantum processor by updating parameters with a classical computer. Such a hybrid qu…
