Nobody checked which state IBM's flagship quantum chemistry results compute

A critical audit of IBM's flagship quantum chemistry demonstrations reveals that published results claiming utility-scale quantum computing success did not actually converge to their stated target quantum states—the calculations achieved lower energies but with incorrect spin properties (⟨S²⟩ = 1.37 instead of singlet state), and showed no advantage over random controls. This finding undermines claims of near-term quantum advantage in chemistry simulations and exposes a significant validation gap in quantum benchmarking practices, requiring IT leaders to reassess quantum computing ROI projections and implementation timelines. Organizations must now demand rigorous validation protocols including spin-state certification as standard benchmarking requirements before committing to quantum computing investments.
