Qedma Quantum Computing and IBM have revealed a joint scientific breakthrough proving that error-mitigated quantum hardware can surpass leading classical supercomputing algorithms in simulating complex materials physics.
By pairing Qedma’s Quantum Error Suppression and Error Mitigation (QESEM) software with cloud-accessible IBM quantum systems, researchers evaluated complex quantum dynamics across systems of up to 74 qubits. The experiment reached a threshold where multiple state-of-the-art classical simulation methods-including executions on one of the world’s premier supercomputers-failed to yield consistent results.
The benchmark marks a pivotal shift: demonstrating that commercially available quantum hardware and error-reduction software can function as trusted scientific instruments. This capability lays the foundation for designing next-generation optoelectronics, light-induced superconductors, and novel advanced materials.
Outperforming State-of-the-Art Classical Supercomputers
The joint initiative targeted the complex oscillatory behavior of a two-dimensional Floquet Ising model-a foundational framework used by theoretical physicists to study how magnetic properties evolve under periodic external forces. Modeling these dynamics over extended timescales has historically pushed classical compute architectures past their limits.

Utilizing the cloud-based IBM Quantum Heron processor alongside Qedma’s QESEM software engine, the research team successfully resolved these quantum dynamics with high fidelity.
To rigorously test the validity of the quantum output, the team partnered with RIKEN, Japan’s premier research institution, and quantum simulation developer BlueQubit. Together, they pitted the quantum results against diverse classical simulation paradigms run on RIKEN’s Fugaku supercomputer. As system complexity scaled, every classical model diverged and lost consistency, whereas the error-mitigated quantum architecture produced stable, long-time oscillatory patterns.
Ahead of their formal pre-print publication on arXiv, the research team uploaded the underlying quantum circuits and experimental datasets to the public Quantum Advantage Tracker to encourage ongoing open-source benchmarking.
“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. I look forward to seeing future results benchmarked through the Quantum Advantage Tracker as we deepen our understanding of the boundary between quantum and classical computation,” said Jay Gambetta, Director of IBM Research and IBM Fellow. “By combining IBM’s quantum computers with Qedma’s advanced error reduction technology, we are transforming quantum computing into a practical tool to expand the frontier of knowledge.”
“For decades, quantum computing has promised discoveries beyond the reach of classical computers. Today, we’re beginning to see that promise become reality,” said Dr. Asif Sinay, CEO and co-founder of Qedma. “By leveraging Qedma’s software to make today’s quantum computers significantly more powerful and reliable, we’re helping move the quantum computing industry closer to real-world, commercial impact.”
“Quantum computers are beginning to open new possibilities for scientific discovery within the high-performance computing environment,” said Dr. Mitsuhisa Sato, Division Director of the Quantum-HPC Hybrid Platform Division, RIKEN Center for Computational Science. “This work leveraged RIKEN’s leadership in advanced classical simulation and supercomputing, alongside Qedma’s error mitigation software on IBM quantum computers, to demonstrate the ability of quantum computing to surpass the capabilities of leading classical methods. It is an important step towards a future where quantum and classical computing work together to advance science.”
Multi-Layer Validation Across Hardware Platforms
To ensure the measured signals reflected genuine physical behavior rather than hardware noise or mitigation artifacts, the collaboration established a multi-tiered validation workflow:
The uniform dynamics observed across distinct quantum hardware platforms confirm that error-mitigated quantum processors can produce repeatable, verifiable scientific discoveries prior to the arrival of fully fault-tolerant, fault-tolerant quantum computers.
Democratizing Error Mitigation via Qiskit
Qedma’s QESEM software is available through the Qiskit Functions Catalog on the IBM Quantum Platform. The platform employs patented algorithmic techniques to suppress hardware noise dynamically, unlocking immediate utility for large-scale, complex workloads without waiting for fault-tolerant architectures.
QESEM features an unbiased error mitigation option that provides mathematical guarantees of accuracy when extracting signals from noisy intermediate-scale quantum (NISQ) devices. The solution is actively deployed across enterprise research divisions, academic centers, and national laboratories worldwide.
