Final errors, E* − Eexact, in repeated executions of VQE + BOIS ground state energy estimates for H2, LiH and the quantum spin model with the IBM Quantum device used indicated by plot colour. We do not observe any clear, systematic differences between the different devices. Error bars indicate standard error on final energy measurements.
