SQD-Enabled Circuit Compression for Resource-Efficient Quantum Chemistry

This work reveals and exploits this underexplored robustness property: how much non-Clifford and variational expressivity can be removed from the sampling circuit before SQD accuracy degrades, and answers through two complementary compression techniques: gradient-based operator pruning, which discards low-impact excitation operators, and Clifford rounding, which snaps remaining parameters to the nearest Clifford angle.

Q-Score: A Quantum-Native Scoring Function for Molecular Docking

Q-Score is introduced, encoding GNN-predicted orbital donor-acceptor energies into a weighted graph and scoring binding by solving a maximum-weight vertex clique problem via Digitized-Counterdiabatic QAOA, enriching for strong orbital interactions at twice the random rate.
