VQE and QAOA scaled energy \(\epsilon _{\psi }\) (top panels) and ground state frequency \(P_{\psi }(\mathrm{gs})\) (bottom panels) for the JSP instance using 5 qubits and 1000 shots on the IBM quantum processors indicated in the legend. The energy was rescaled with the minimum and maximum energy eigenvalues. Both VQA use the CVaR objective with \(\alpha =0.5\). Error bands are the standard deviation (top panels) and 95% confidence interval (bottom panels) (for clarity, error bands only shown for the solid line)
