In this paper, a symmetric Variational Quantum Eigensolver (VQE) algorithm is introduced to solve the ground state energy of symmetric Hamiltonian efficiently. As the symmetry of Hamiltonian is always broken by the typical VQE, hence the symmetric VQE proposed here is to increase the efficiency of t...
