SEEQC has announced the integration of its Digital Interface System with NVIDIA’s NVQLink, enabling a fully digital, real-time connection between quantum processing units (QPUs) and graphics processing units (GPUs). This integration, demonstrated by NVIDIA during its GTC event in Washington, DC, employs NVIDIA’s open NVQLink architecture to support ultra-low-latency communication between leading QPU architectures and NVIDIA GPUs.
The Digital Interface System leverages SEEQC’s all-digital link protocol and quantum computing-on-a-chip hardware, driven by energy-efficient Single Flux Quantum (SFQ) logic operating above 20 GHz. The system achieves microsecond-scale interface latency and sub-100-microsecond logical compute throughput by utilizing decoders within the NVIDIA CUDA-Q platform. SEEQC claims this approach eliminates traditional logical data bottlenecks between QPUs and GPUs by more than 1,000 times compared to analog-based systems, while enabling microsecond operations critical for scalable quantum error correction and quantum-AI workloads in data center environments.
SEEQC reports that integrating with NVIDIA’s high-throughput NVQLink architecture provides the performance, scalability, and reliability needed for practical, fault-tolerant quantum computing beyond the limitations of current hybrid analog systems. The company targets this technology at developers of quantum computing systems, including those building data center-scale quantum-classical architectures.
“Combining the state of the art in quantum and classical compute is crucial for allowing real-time operation of the error corrected, logical qubits that are defining the next generation of quantum accelerated computers,” said Tim Costa, General Manager for Quantum at NVIDIA. “SEEQC’s integration of NVIDIA NVQLink enables the high-performance computing infrastructure integration necessary to bridge quantum and classical systems for next-generation supercomputers.”
SEEQC develops superconducting digital chips, firmware, and software for scalable, energy-efficient quantum computing platforms, with manufacturing and R&D facilities in New York, London, and Naples.
