Key Chemistry Question Answered, No Quantum Computer Required

If a chemical puzzle, once a quantum target, is solved classically, what does that reveal?This piece, published last week, lands right in the middle of a fascinating debate about the future of scientific discovery. For years, the incredibly complex chemistry behind life-sustaining enzymes like nitrogenase has been held up as a problem only solvable by future quantum computers. But what if we don't have to wait? One chemist, Garnet Chan, and his team just made a breakthrough using purely classical methods, pushing back on the idea that these problems are out of reach until quantum hardware arrives.Researchers have successfully determined the ground-state energy of FeMo-co, the active site of the enzyme nitrogenase, using purely classical computational methods. This milestone challenges the assumption that quantum computers are required to understand such complex entangled chemical systems, contributing to the ongoing debate about the comparative advantages of classical and quantum computing in chemistry.Read at source: Quanta Magazine
