NVIDIA has launched NVQLink, an open system architecture for tightly coupling GPU computing with quantum processors to build accelerated quantum supercomputers. The platform is designed to provide the demanding low-latency, high-throughput interconnect required for the complex control algorithms of large-scale quantum computing and Quantum Error Correction (QEC). The development of NVQLink was guided by researchers from leading supercomputing centers at nine U.S. national laboratories, including Brookhaven National Laboratory, Fermi Laboratory, and Oak Ridge National Laboratory.
NVQLink is integrated with the NVIDIA CUDA-Q platform and supports 17 Quantum Processing Unit (QPU) builders and five control system providers. The interconnect enables researchers and developers to create and test hybrid quantum-classical systems, accelerating applications in chemistry and materials science. Jensen Huang, founder and CEO of NVIDIA, positioned NVQLink as the critical technology uniting quantum and classical supercomputers into a single, coherent system.
Multiple key partners simultaneously announced their adoption of the architecture:
- Pasqal (Neutral Atom): Integrates its QPUs to enable better logical architectures and accelerate roadmaps toward Fault-Tolerant Quantum Computing (FTQC).
- IQM (Superconducting): Combines NVQLink with its IQM Constellation processor architecture and Zurich Instruments’ control systems, targeting real-time decoding and control at scale.
- Alice & Bob (Cat Qubit): Utilizes the platform for logical orchestration, decoding, and live calibration, allowing GPUs to perform tasks previously limited to dedicated hardware.
- Quantum Machines (QM) (Control Systems): The open architecture extends QM’s microsecond-latency control solution, enabling real-time data exchange and deterministic feedback.
The U.S. Secretary of Energy stated that the collaboration between national laboratories, startups, and industry partners like NVIDIA is central to the mission of maintaining America’s leadership in HPC and solving grand scientific challenges. This widespread adoption of a standardized interface is intended to accelerate the global timeline for hybrid quantum-classical computing.
