Towards estimating molecular ground state energies on current quantum hardware — •Felix Rupprecht and Sabine Wölk — Institute of Quantum Technologies, German Aerospace Center (DLR), Ulm, Germany

Quantum simulation may achieve a quantum advantage in the near future. One immediate application is then the design of materials for energy storage systems. In the QuESt project we aim at estimating ground and exited states of relevant molecules using variational quantum eigensolvers. In order to get meaningful results on current noisy intermediate scale quantum (NISQ) computers, efficient algorithm implementation and error mitigation techniques are needed.

We present first results on running variational quantum eigensolvers with a unitary coupled cluster (UCC) ansatz on current IBM superconducting quantum processors using error mitigation methods such as zero noise extrapolation.

The QuESt project is funded by the Baden-Württemberg Ministry of Economic Affairs, Labour and Housing.
