a Parametrized quantum circuit for the generation of the protein configurations. The optimal set of qubit gate rotations is used to reconstruct the optimal fold. b Schematic representation of the ibmq_poughkeepsie 20-qubit backend used in this experiment. Qubit 7 is used to close the loop by swapping with qubit 8. c Converged maximal ground state probability for the ground state fold, \(\mathop{\max }\nolimits_{p}{{\mathbb{P}}}_{0}(p)\). d Evolution of the ground state probability during the CVaR-VQE minimization (i.e., number of generations) with α parameter set to 5%. e Evolution of the mean probability (over the population ensemble, \(\langle {{\mathbb{P}}}_{0}(p)\rangle\)) and of the best individual probability for the ground state fold, \(\mathop{\max }\limits_{p}{{\mathbb{P}}}_{\text{0}}(p)\).
