Insights

Quantum-classical integration strategist

Rigetti joins NVIDIA NVQLink to enable low-latency, high-throughput quantum–classical integration showcased at GTC.

Rigetti supports NVIDIA NVQLink, an open platform to link CPUs, GPUs and QPUs for hybrid workloads, and it is demonstrating that work at NVIDIA GTC in Washington, D.C. The announcement highlights prior integration of a Novera™ QPU with NVIDIA DGX Quantum for QPU calibration using AI.

The business mechanism is straightforward: NVQLink provides an interoperable, low-latency fabric to route control and data between classical supercomputers and quantum processors. Successful integration reduces control overhead and could speed development of hybrid algorithms, provided latency and throughput targets meet practical thresholds.

Key dependencies and risks include measurable latency, sustained throughput, and broad adoption by supercomputing centers and QPU vendors. The announcement reports demonstrations but contains no quantitative performance metrics, so technical benefit remains unverified until benchmark data or production deployments appear.

Concrete items to watch: public latency/throughput benchmarks, additional NVQLink integrations beyond this demo, and follow-up announcements from the GTC demonstration on October 28, 2025. Expect informative updates or benchmarks within weeks to months after the event, which will clarify practical impact for hybrid quantum-classical workloads.

BERKELEY, Calif., Oct. 28, 2025 (GLOBE NEWSWIRE) -- Rigetti Computing, Inc. (Nasdaq: RGTI) (“Rigetti” or the “Company”), a pioneer in full-stack quantum-classical computing, announced today that it is supporting NVIDIA NVQLink, NVIDIA’s new open platform for integrating AI supercomputing with quantum computers.

Rigetti is exhibiting its collaboration with NVIDIA NVQLink at the Quantum Computing Pavilion at NVIDIA GTC Washington, D.C. NVIDIA GTC attendees can also view a full-scale demonstration of a Rigetti quantum computer in NVIDIA’s booth throughout the event.

It is widely believed that utility-scale quantum computing will be realized through the tight integration of quantum computers with classical computing systems. Rigetti’s quantum computing processors, which are powered by superconducting qubits, are ideal for hybrid systems given their fast gate speeds and scalability.

“Rigetti is proud to work with NVIDIA in support of the rapidly evolving quantum ecosystem,” says Dr. Subodh Kulkarni, Rigetti CEO. “By providing low latency and high throughput of quantum hardware and AI supercomputing, NVQLink is a very promising resource to accelerate hybrid computation development as we work towards quantum advantage.”

"NVQLink unites quantum processors and control systems with NVIDIA AI supercomputing, delivering a turnkey solution for integrating and scaling quantum hardware," said Tim Costa, General Manager for Quantum at NVIDIA. "NVIDIA and Rigetti are working together to provide low-latency, high-throughput connectivity between CPUs, GPUs and QPUs, accelerating the development of hybrid quantum-classical applications and accelerated quantum supercomputers."

NVQLink is an open and interoperable architecture for adding real-time, scalable, accelerated computing to quantum processing via the NVIDIA CUDA-Q platform. Low latency and high-throughput connectivity between CPUs, GPUs, QPUs and their control systems allows developers to unlock the computationally demanding control tasks needed for building logical qubits and running useful hybrid quantum-classical applications. NVQLink allows supercomputing centers and QPU and quantum control vendors to easily, reliably, and performantly integrate their systems and build tomorrow’s accelerated quantum supercomputers.

This builds on Rigetti’s previous work with NVIDIA to leverage AI tools for quantum computing operations. The teams previously integrated a Novera™ QPU with NVIDIA DGX Quantum to successfully calibrate the QPU, demonstrating how AI can accelerate quantum computer setup while maintaining the exacting standards required for quantum computation.
