Researchers have demonstrated that a characterization-based error mitigation technique called QESEM can achieve "chemical accuracy" for molecular simulations on current noisy quantum hardware. By mapping device-specific flaws without relying on biased noise assumptions, the team successfully calculated water molecule energy surfaces within 1.5 milliHartree using existing processors like Aachen. While this proves meaningful potential energy surfaces are attainable today, the method incurs significant computational overhead due to extensive sampling requirements.
