Optimized VQE variants with Gray code encoding and zero-noise extrapolation achieve improved accuracy for nuclear shell-model energies of 38Ar and 6Li in noisy simulations.
The reduced number of qubits and gates in GC encoding significantly improves the accuracy of computed energies compared to JW, which uses 6 qubits for all J π states
