Quantum Computation of Electronic Transitions Using a Variational Quantum Eigensolver

Author(s): Robert M. Parrish, Edward G. Hohenstein, Peter L. McMahon, and Todd J. Martínez
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 asso...
