Quandela and NVIDIA released a joint white paper at IEEE Quantum Week 2026 outlining a photonic QPU integration architecture using NVIDIA’s NVQLink. The framework connects Quandela’s Quantum System Controller, which manages FPGA‑based pulse control for its MosaiQ QPU, directly to NVIDIA GPU nodes via a low‑latency Remote Direct Memory Access (RoCE) interconnect. Sub‑4‑microsecond round‑trip latency enables microsecond‑scale GPU‑QPU communication, supporting GPU‑accelerated state‑vector simulations, real‑time quantum error correction, and automated pulse calibration within a unified CUDA‑Q host process. The paper details a three‑phase commercial roadmap—Access, Integration & Discovery, and Scale—and highlights the partnership’s potential to embed photonic quantum processors in existing HPC data centers.
