Spin-state energetics of heme-related models with the variational quantum eigensolver

Unathi Skosana, Sthembiso Gumede, Mark Tame

We present numerical calculations of the energetic separation between different spin states (singlet, triplet and quintet) for a simplified model of a deoxy-myoglobin protein using…
