NVIDIA has launched NVQLink, an open high-speed interconnect designed to fuse the performance of GPU computing with emerging quantum processors. Developed in collaboration with 17 quantum hardware developers and nine U.S. national laboratories, NVQLink establishes a unified link between classical and quantum computing architectures.
The system enables low-latency communication between quantum processing units and conventional supercomputers — a critical capability for the calibration, error correction, and control algorithms that underpin practical quantum applications. Among the laboratories contributing to NVQLink’s development are Brookhaven, Fermi, Lawrence Berkeley, Los Alamos, MIT Lincoln, Oak Ridge, Pacific Northwest, and Sandia National Laboratories.
Described by NVIDIA founder and CEO Jensen Huang as “the Rosetta Stone connecting quantum and classical supercomputers,” NVQLink represents a shift toward hybrid scientific architectures that can handle the error-prone nature of qubits while maintaining the computational throughput of GPU clusters. The technology integrates directly with NVIDIA’s CUDA-Q software platform, allowing developers to design, test, and deploy hybrid applications across CPUs, GPUs, and quantum processors within a single workflow.
U.S. Secretary of Energy Chris Wright said the Department of Energy views the technology as “a critical bridge to the next era of accelerated quantum supercomputing,” adding that it will support new breakthroughs in materials science, chemistry, and large-scale simulations.
Quantum hardware partners contributing to the NVQLink ecosystem include Alice & Bob, Atom Computing, IonQ, Oxford Quantum Circuits, Pasqal, Quantinuum, Rigetti, and Silicon Quantum Computing, alongside quantum control specialists such as Keysight Technologies, Qblox, and Zurich Instruments.
Keysight, whose Quantum Control System (QCS) supports scalable quantum experimentation, confirmed at GTC Washington that it is working closely with NVIDIA to advance hybrid quantum–AI infrastructure. “Leadership means defining the standards that make transformative technologies universally accessible,” said Dr Eric Holland, General Manager for Keysight Quantum Engineering Solutions. “By establishing a framework for quantum–HPC hybrid compute, we’re shaping the future fabric of scientific discovery.”
Tim Costa, NVIDIA’s General Manager for Quantum, noted that NVQLink provides “the open unified interface for developing what comes next” — hybrid computing environments where quantum precision meets AI acceleration.
By directly linking quantum processors with GPU supercomputers, NVQLink sets the foundation for hybrid research environments capable of addressing previously intractable computational problems. The initiative marks a key step toward the deployment of quantum-enabled AI systems across national laboratories and industrial research centres in the coming decade.
