NVIDIA has unveiled NVQLink™, an open system architecture designed to seamlessly integrate the power of GPU computing with quantum processors, marking a major step toward building accelerated quantum supercomputers. Announced at GTC Washington, D.C., the technology enables tight coupling between classical supercomputing infrastructure and quantum hardware, creating a unified platform for next-generation computing. The development of NVQLink was guided by leading supercomputing centers at U.S. national laboratories, including Brookhaven National Laboratory, Fermilab, Lawrence Berkeley National Laboratory, Los Alamos National Laboratory, MIT Lincoln Laboratory, Oak Ridge National Laboratory, Pacific Northwest National Laboratory, and Sandia National Laboratories. These institutions played a key role in shaping the architecture to meet the demanding requirements of quantum computing research. Qubits—the fundamental units of quantum information—are inherently fragile and prone to errors, requiring precise calibration, quantum error correction, and real-time control algorithms to function reliably. These processes demand ultra-low latency and high-throughput communication between quantum processors and classical supercomputers. NVQLink delivers this critical interconnect, providing the infrastructure needed to manage qubit stability and unlock practical quantum applications. “In the near future, every NVIDIA GPU scientific supercomputer will be hybrid, tightly coupled with quantum processors to expand what is possible with computing,” said Jensen Huang, founder and CEO of NVIDIA. “NVQLink is the Rosetta Stone connecting quantum and classical supercomputers — uniting them into a single, coherent system that marks the onset of the quantum-GPU computing era.” The U.S. Department of Energy’s national laboratories will leverage NVQLink to advance quantum research and maintain America’s leadership in high-performance computing. “Maintaining America’s leadership in high-performance computing requires us to build the bridge to the next era of computing: accelerated quantum supercomputing,” said U.S. Secretary of Energy Chris Wright. “The deep collaboration between our national laboratories, startups, and industry partners like NVIDIA is central to this mission — and NVIDIA NVQLink provides the critical technology to unite world-class GPU supercomputers with emerging quantum processors, creating the powerful systems we need to solve the grand scientific challenges of our time.” NVQLink supports a broad ecosystem, including 17 quantum processor builders and five quantum control system developers. It offers a standardized, turnkey solution that addresses the complex integration challenges faced by quantum researchers as they scale their hardware. The architecture is integrated with NVIDIA’s CUDA-Q™ software platform, allowing developers and researchers to design and test hybrid applications that leverage CPUs, GPUs, and quantum processors in a unified workflow. This integration accelerates progress in control algorithms, calibration, quantum error correction, and hybrid application development. Contributors to the NVQLink initiative include quantum hardware providers such as Alice & Bob, Anyon Computing, Atom Computing, Diraq, Infleqtion, IonQ, IQM Quantum Computers, ORCA Computing, Oxford Quantum Circuits, Pasqal, Quandela, Quantinuum, Quantum Circuits, Inc., Quantum Machines, Quantum Motion, QuEra, Rigetti, SEEQC, and Silicon Quantum Computing. Quantum control system builders like Keysight Technologies, Quantum Machines, Qblox, QubiC, and Zurich Instruments also played a key role.
