IBM Quantum Computing and Qedma Quantum Computing announced a breakthrough 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. By combining Qedma Quantum Computing's advanced error mitigation software, QESEM, with IBM Quantum Computing quantum computers, researchers observed complex and long-lived quantum dynamics in systems of up to 74 qubits. The collaboration investigated the subtle, oscillatory dynamics of a two-dimensional Floquet Ising model.
Using an IBM Quantum Computing quantum computer, which is powered by the IBM Quantum Computing Quantum Heron processor and available on the cloud, together with Qedma Quantum Computing's Quantum Error Suppression and Error Mitigation (QESEM) software, which is also available on the cloud, the team was able to resolve these dynamics with precision. The team worked with RIKEN and BlueQubit to compare them against classical simulation approaches. As the system grew in complexity over time, none of the classical approaches could consistently agree at the scale reached by the quantum experiments, even when run on Fugaku.
The error-mitigated quantum results remained consistent and revealed clear, long-time oscillatory behavior. The team publicly released the quantum circuits and results to the Quantum Advantage Tracker prior to the arXiv pre-print released this week. The team first employed an unbiased error-mitigation protocol against classical calculations wherever such comparisons remained possible, before pushing the protocol to the point where these classical simulations lost accuracy.
Then, they benchmarked a more scalable mitigation approach against those trusted results before extending to larger system sizes and longer evolution times. Independent validation was also performed across quantum hardware platforms, including trapped-ion systems from Quantinuum. The consistent behavior observed across technologies provided additional evidence that the measured physics originated from the simulated quantum system, rather than from device-specific or mitigation errors.
Qedma Quantum Computing's advanced error reduction software, QESEM, available in the Qiskit Functions Catalog on the IBM Quantum Computing Quantum Platform, mitigates the impact of noise present in quantum computers. QESEM's patented approach unlocks the ability to execute larger and more complex quantum workloads while producing more accurate results. The software offers various error mitigation methods, including an unbiased approach which provides guaranteed accuracy in extracting reliable results from noisy quantum hardware.
It is currently being used by enterprises, academic institutions, and research laboratories around the world.
