the Quantum Medical Cure: How Computing Is Being Built to Transform Medicine, Drug Discovery, and Fight Against Cancer

Drug discovery's hardest computational problems cluster around a small set of chemical features that classical methods handle poorly. Transition metals, common in the catalytic centers of enzymes, have electron configurations that classical force fields must approximate crudely. Molecules with unpaired electrons, known as radicals, behave in ways that defy the simplifying assumptions built into most classical chemistry software. And binding pockets where a drug candidate must fit with sub-angstrom precision often hinge on energy differences too small for classical approximation to resolve reliably. Quantum computing's proponents argue, and a growing body of research supports, that these are exactly the cases where a quantum processor's native ability to represent electronic structure could produce answers that classical methods simply cannot reach, regardless of how much supercomputing power is thrown at the problem.
