Oak Ridge National Laboratory

In 2024-2025, Oak Ridge National Laboratory achieved several major quantum computing milestones. In September 2025, Riverlane's Deltaflow 2 real-time quantum error correction system was installed at ORNL, marking the first dedicated real-time QEC integration at a U.S. national laboratory. Also in September 2025, ORNL and Australian-German company Quantum Brilliance inaugurated the United States' first on-site commercial quantum-computer cluster, the first of its kind to integrate a diamond-based quantum processor into a high-performance computing (HPC) environment. On August 29, 2025, ORNL released a comprehensive study outlining software architecture designed to integrate quantum computers with the world's fastest supercomputers, notably the exascale machine Frontier. In November 2024, ORNL added IQM Resonance quantum cloud service to its Quantum Computing User Program. In August 2025, ORNL researchers developed a quantum microscope for nanoscale imaging and a multihop quantum network integrating with fibre-optic infrastructure. These developments demonstrate ORNL's leadership in quantum-HPC integration.
