Combining advanced software with commercially available hardware, Qedma Quantum Computing and IBM report achieving quantum advantage in modeling complex physical systems. Researchers used Qedma’s QESEM software alongside IBM quantum computers to accurately resolve dynamics within systems of up to 74 qubits, a scale where leading classical simulations, including those run on RIKEN’s Fugaku supercomputer, could not deliver consistent results. IBM stated that this enabled them to reach a point where multiple classical approaches failed to provide consistent, reliable answers, marking the first demonstration of this capability with accessible technology for scientific exploration.
QESEM Software and IBM Quantum Systems Enable Error-Mitigated Computation
At a scale of 74 qubits, quantum systems paired with sophisticated software are now demonstrably outperforming the most powerful classical supercomputers in modeling complex physical phenomena. The collaboration specifically targeted the dynamics of a two-dimensional Floquet Ising model, a system used to study magnetic properties under rhythmic external pulses, a challenge that rapidly overwhelms classical computational methods.
Researchers utilized an IBM quantum computer, powered by the IBM Quantum Heron processor and accessible via the cloud, alongside Qedma’s QESEM software, also cloud-based, to resolve these dynamics with increased precision. To rigorously validate this quantum advantage, the team benchmarked their results against classical simulations run on Fugaku, one of the world’s leading supercomputers, in collaboration with RIKEN and BlueQubit.
As the complexity of the system increased, classical approaches consistently failed to provide reliable answers, even with the immense processing power of Fugaku; however, the error-mitigated quantum results remained consistent, revealing clear oscillatory behavior. The quantum circuits and results have been publicly released to the Quantum Advantage Tracker to facilitate further classical benchmarking. A key feature of this work is its comprehensive validation strategy. The team initially employed an unbiased error-mitigation protocol against classical calculations, then benchmarked a scalable mitigation approach against those trusted results before extending to larger system sizes and longer evolution times.
Independent validation was also performed using trapped-ion systems from Quantinuum, further solidifying the evidence that the observed physics originated from the quantum system itself, rather than from device-specific errors. Jay Gambetta, Director of IBM Research and IBM Fellow, said that IBM quantum computers have reached a maturity where they can produce solutions that, for the first time, achieve both trust in the solution through extensive testing and outperform the best classical simulation methods.
He added that he looks forward to seeing future results benchmarked through the Quantum Advantage Tracker as we deepen our understanding of the boundary between quantum and classical computation. Qedma’s QESEM software, available within the Qiskit Functions Catalog on the IBM Quantum Platform, actively mitigates the impact of noise inherent in current quantum computers.
Dr. Asif Sinay, CEO and co-founder of Qedma, stated that by combining IBM’s quantum computers with Qedma’s advanced error reduction technology, they are transforming quantum computing into a practical tool to expand the frontier of knowledge, unlocking the ability to execute more complex quantum workloads and produce more accurate results without waiting for the development of fully fault-tolerant quantum computers.
