QAOA scaled energy \(\epsilon _{\psi }\) (top panels) and ground state frequency \(P_{\psi }(\mathrm{gs})\) (bottom panels) for the 5-qubit JSP instance with CVaR (a) \(\alpha =0.5\) and (b) \(\alpha =0.2\). For other settings, see Table 2. The energy was rescaled with the minimum and maximum energy eigenvalues. Error bands are the standard deviation (top panels) and 95% confidence interval (bottom panels) (for clarity, error bands only shown for the solid line)
