QSCI-CMP: Quantum-Selected Configuration Interaction with Chemically Motivated Preselection
QSCI-CMP is a quantum-classical hybrid method for molecular ground-state calculations that reduces query and gate counts compared to sample-based methods like SQD-AA. It achieves this by identifying and fixing 'chemically trivial' states beforehand, treating them as already sampled. This reserves quantum resources for complex determinants, leading to significant cost savings.
