Diraq’s Ultrafast Qubits Accelerated by NVIDIA NVQLink

Diraq’s silicon spin qubits are exceptionally fast, performing up to a million fault-tolerant operations in under a minute — but this speed demands a powerful, low-latency interface to manage control, error correction and hybrid quantum-classical processes. NVIDIA’s new NVQLink provides that capability, replacing the earlier DGX Quantum system. NVQLink offers Diraq an open, high-performance platform for orchestrating its quantum processing unit (QPU) alongside the classical computing infrastructure needed for real-time control and analysis.

At NVIDIA AI Day, Diraq’s Head of Theory, Dr Andre Saraiva, highlighted that NVQLink not only boosts processing speed but also enables wider collaboration through its familiarity and accessibility. Diraq is already working with Sandia National Labs to use NVQLink for real-time calibration and machine-learning-driven noise characterisation, supported by NVIDIA’s CUDA-Q hybrid software tools. Looking ahead, Diraq plans to partner with Iceberg Quantum to apply advanced qLDPC error-correction codes, relying on NVQLink’s classical compute power to scale towards utility-grade quantum systems capable of running useful applications.
