New Q-Score method uses quantum mechanics for molecular docking

Researchers have developed Q-Score, a novel scoring function for molecular docking that incorporates quantum-mechanical effects, unlike traditional methods. This new approach uses graph neural networks to predict orbital donor-acceptor energies, which are then used to solve a maximum-weight vertex clique problem via Digitized-Counterdiabatic QAOA. The method has shown promise in accurately recovering optimal solutions and enriching for strong orbital interactions, with initial tests on IBM Eagle hardware indicating solvability on NISQ devices.
