Researchers from Qunova Computing and collaborators introduce a dynamic information exchange between quantum and classical computing to improve accuracy and scalability. The work benchmarks HI-VQE against benchmark cases, including the nitrogen molecule (N2) dissociation and an iron-sulfur cluster (Fe-S), testing static correlation and dynamic correlation. The team compares results to HCI benchmarks, assessing how well the method captures multireference effects. They also integrate stochastic SHCI and tensor-network methods like DMRG to refine active-space calculations. The findings point toward a feasible path for simulating bioinorganic molecules, catalytic mechanisms, and other materials where classical methods struggle.
