NVIDIA NVQLink connects quantum processors with GPU computing to enhance research capabilities

NVIDIA launched NVQLink, an open system architecture designed to connect Graphics Processing Unit (GPU) computing with quantum processors. This integration aims to enhance the development of accelerated quantum supercomputers.

The NVQLink high-speed interconnect facilitates connections between quantum processors and leading supercomputing laboratories, such as Brookhaven National Laboratory and Lawrence Berkeley National Laboratory. It supports 17 Quantum Processing Unit (Quantum Processor Unit (QPU)) builders and five controller builders, promoting collaboration among nine U.S. national labs.

Qubits, responsible for processing information in quantum computing, require complex calibration and error correction algorithms. These algorithms depend on low-latency, high-throughput connections to conventional supercomputers, which NVQLink provides.

Jensen Huang, founder and CEO of NVIDIA, stated, “In the near future, every NVIDIA GPU scientific supercomputer will be hybrid, tightly coupled with quantum processors to expand what is possible with computing.” U.S. Secretary of Energy Chris Wright emphasized that maintaining the country's leadership in High performance computing (HPC) involves bridging to accelerated quantum supercomputing.

NVQLink connects various quantum processors and control systems to Artificial Intelligence (AI) supercomputing, offering a unified solution to the integration challenges faced by quantum researchers while scaling their hardware.

Researchers can leverage the NVQLink through its integration with NVIDIA CUDA-Q™ software, enabling application development that utilizes CPUs, GPUs, and quantum processors. This sets a foundation for advancing hybrid quantum-classical supercomputers.
