Calculations on H2 were performed with a hardware-efficient circuit on the Särimner device of Chalmers, employing 50,000 samples. Calculations for LiH were performed on ibmq_quito utilizing a hardware-efficient two-local ansatz using 8192 samples. To reduce the effects of noise, readout mitigation was applied to all hardware calculations. Calculations of H2 and LiH made use of parity encoding to reduce the required number of qubits and circuit depths.
