This study demonstrates that Qedma's QESEM error mitigation software significantly enhances the reliability of quantum chemistry simulations on current noisy hardware, achieving a 30–50× accuracy boost over raw results. By successfully mapping the potential energy surface of a water molecule on IBM's Aachen processor, the research validates critical algorithms needed for practical quantum advantage in chemical modeling before fault-tolerant devices are available.
