Quandela Validates Low-Latency Photonic QPU Integration with NVIDIA Infrastructure using NVQLink

Traditional cloud-style QPU access. Each iteration traverses cloud APIs, queues and schedulers before reaching the QPU.

French photonic quantum computing developer Quandela has experimentally validated a low-latency hardware integration path that connects its photonic Quantum Processing Units (QPUs) directly with NVIDIA accelerated high-performance computing (HPC) infrastructure. Presented at the ISC High Performance 2026 conference in Hamburg, Germany, the architecture moves beyond traditional cloud-hosted application programming interfaces (APIs) and asynchronous job queues. By leveraging the NVIDIA NVQLink interconnect, the milestone establishes a collocated, real-time hybrid computing pipeline where a quantum processor functions as a tightly coupled hardware accelerator alongside GPU clusters.
