Error Mitigation by Symmetry Verification on a Variational Quantum Eigensolver
R. Sagastizabal, X. Bonet-Monroig, M. Singh +11
Variational quantum eigensolvers offer a small-scale testbed to demonstrate the performance of error mitigation techniques with low experimental overhead. We present successful err…

Low-cost error mitigation by symmetry verification
X. Bonet-Monroig, R. Sagastizabal, M. Singh +1
We investigate the performance of error mitigation via measurement of conserved symmetries on near-term devices. We present two protocols to measure conserved symmetries during the…
