Eigenvector continuation (EC) has recently attracted a lot attention in nuclear structure and
reactions as a variational resummation tool for many-body expansions. While previous …

We propose a scheme to restore spatial symmetry of Hamiltonian in the variational-quantum-
eigensolver (VQE) algorithm for which the quantum circuit structures used usually break the …

Hybrid quantum-classical variational algorithms such as the variational quantum
eigensolver (VQE) and the quantum approximate optimization algorithm (QAOA) are …
