A method, system and computer program product for generating optimal samples in quantum optimization algorithms. A quantum error mitigation technique is used to generate samples of a resulting probability distribution from random quantum circuits. Examples of such quantum error mitigation techniques include probabilistic error cancellation (PEC) and zero noise extrapolation (ZNE). An objective (ƒ(x)) for every generated sample (|x) is then computed. A conditional value at risk (CVaR) at a particular level of the computed objective functions corresponding to an optimal sample in a quantum optimization algorithm, such as a variational quantum optimization algorithm, is then computed. In this manner, optimal samples in quantum optimization algorithms are generated using quantum error mitigation techniques, such as probabilistic error cancellation and zero noise extrapolation.
