IBM and Qedma Demonstrate Quantum Advantage, Modeling Physics Beyond Classical Capabilities Through Trusted Quantum Computation

Details

IBM and Qedma Quantum Computing announced a quantum advantage demonstration that combines IBM's cloud-accessible quantum hardware (Heron processor) with Qedma's QESEM error mitigation software, also cloud-available. The key differentiator from prior quantum advantage claims: both the hardware and software are commercially accessible, not custom research apparatus.\n\nThe physics problem is a two-dimensional Floquet Ising model — studying how a material's magnetic properties oscillate when driven by rhythmic external pulses. The team used systems of up to 74 qubits. For validation, they engaged RIKEN (Japan's national research institute) and BlueQubit to run state-of-the-art classical simulations, including on Fugaku — currently one of the world's most powerful supercomputers. As the quantum system grew in complexity, none of the classical methods could consistently agree, while the error-mitigated quantum results remained coherent.\n\nQedma's QESEM (Quantum Error Suppression and Error Mitigation) software was essential — it corrects errors in the quantum computation without requiring perfect physical qubits, enabling commercially available hardware to reach results classical methods cannot. The result opens potential applications in ultrafast optoelectronics and light-induced superconductors.\n\nThis is the first time quantum advantage has been claimed with commercially available hardware and software, lowering the access bar for future advantage demonstrations.
