IBM, Qedma Quantum Computing demonstrate error-mitigated quantum computation

Qedma Quantum Computing and IBM (IBM) announced a study demonstrating how trusted, error-mitigated quantum computation is possible, and can be used to explore the physics of materials beyond the capabilities of classical simulations, including those run on one of the world’s most powerful supercomputers. By combining Qedma’s advanced error mitigation software, QESEM, with IBM quantum computers, researchers observed complex and long-lived quantum dynamics in systems of up to 74 qubits. This enabled them to reach a paradigm where multiple classical approaches failed to provide consistent, reliable answers. The company said, “The results mark the first time quantum advantage has been achieved with commercially available hardware and software to establish error-mitigated, advanced quantum computers as trusted scientific instruments for exploring physics that could lead to better and ultrafast optoelectronics, light-induced superconductors, and other advanced materials applications.”
