The top row presents the ground state electronic energy of NaH using the Singlet-Adapated-UCCSD ansatz within the VQE method with different levels of depolarizing noise, p. The bottom row presents the corresponding fidelity of the prepared quantum state and that of the ground state found through conventional means. The left and right columns differentiate the results found using the COBYLA and L-BFGS optimizers, respectively
