Cleveland Clinic, IBM, and RIKEN completed the first large-scale quantum simulation of a protein-ligand complex in explicit water, scaling across 10,000 to 13,000 atoms using an atom-by-atom embedded wave function framework. Dr. Kenneth Merz, Principal Investigator at Cleveland Clinic Research, outlines how this milestone connects to free energy calculations, lead optimization in drug discovery, and the hybrid quantum-classical architecture that defines quantum's role in biomedical research today.
