"singlet fission single photon light absorption of molecule produces 2 excited states... linear H4 molecule's energetic levels match fission process's requirements... PDS quantum solver... double electronic excitations... 2 electrons move up 2 higher energy levels simultaneously... decreased number of qubits reducing problem size, took fewer measurements to solve problem by measuring groups of terms once, instead of implementing each circuit individually ran 4 circuits in parallel using all 20 qubits in the H1-1"
