Quantum Computation of Electronic Transitions Using a Variational Quantum Eigensolver
Quantum Computation of Electronic Transitions Using a Variational Quantum Eigensolver
We develop an extension of the variational quantum eigensolver (VQE) algorithm---multistate contracted VQE (MC-VQE)---that allows for the efficient computation of the transition energies between the ground state and several low-lying excited states of a molecule, as well as the oscillator strengths associated with these transitions. We numerically simulate MC-VQE by …
