Considerations for evaluating thermodynamic properties with hybrid quantum-classical computing work-flows

Stober, Spencer T., Harwood, Stuart M., Greenberg, Donny et al.

Understand

Quantum chemistry applications on quantum computers currently rely heavily on the variational quantum eigensolver (VQE) algorithm.

  • This hybrid quantum-classical algorithm aims at finding ground state solutions of molecular systems based on the variational principle.
  • VQE calculations can be systematically implemented for perturbations to each molecular degree of freedom, generating a Born-Oppenheimer potential energy surface (PES) for the molecule.
  • The PES can then be used to derive thermodynamic properties, which are often desirable for applications in chemical engineering and materials design.
