NVIDIA launches NVQLink to accelerate hybrid quantum supercomputers
NVIDIA has introduced NVQLink, a high-speed interconnect designed to tightly couple GPU-based supercomputing systems with emerging quantum processors. The open system architecture was developed with input from major U.S. national labs and is aimed at enabling large-scale quantum computing research and applications.
This development will interest eeNews Europe readers working in HPC, semiconductor R&D, and quantum system integration, as it addresses one of the biggest bottlenecks in scaling quantum computing: fast, low-latency control and error correction.
Hybrid supercomputing for quantum research
NVQLink links quantum processing units (QPUs) directly to GPU-driven supercomputers, supporting a range of quantum hardware architectures. Researchers from Brookhaven, Fermilab, Lawrence Berkeley National Laboratory, Los Alamos National Laboratory, MIT Lincoln Laboratory, Oak Ridge National Laboratory, Pacific Northwest National Laboratory and Sandia National Laboratories collaborated in its development.
The interconnect executes quantum control algorithms — including quantum error correction — over high-throughput, low-latency channels to stabilize qubits. Qubits are highly sensitive and prone to errors, making real-time correction vital for any practical quantum computing deployment.
“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.”
Industry collaboration and application development
The U.S. Department of Energy sees NVQLink as strategic infrastructure for next-generation research. “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.
NVQLink integrates into NVIDIA’s CUDA-Q software stack, letting developers prototype hybrid applications spanning CPUs, GPUs, and quantum processors. Hardware partners include Atom Computing, IonQ, Pasqal, Quantinuum, Rigetti, QuEra, and others, along with control system suppliers such as Keysight and Zurich Instruments.
