Europe's sovereign quantum push took another small step today, with OVHcloud announcing at the Quantum Defence Summit that Quandela's photonic Belenos computer is now live on its Quantum-as-a-Service platform. It is the second physical quantum processor on the Roubaix-based cloud provider's platform, which launched last autumn with 15 emulators and began offering real hardware shortly after.
Belenos is a 12-qubit photonic machine built by Paris-based Quandela, one of a small group of European photonic specialists alongside PsiQuantum (US/UK) and Xanadu (Canada). Twelve qubits is modest by absolute standards — IBM's roadmap is now measured in the thousands, and Google's Willow chip runs at 105 — but photonic architectures are harder to compare directly. They trade raw qubit count for different advantages: room-temperature operation, longer coherence on specific problems, and easier networking between chips. OVHcloud is pitching Belenos at experimentation rather than breakthrough computation. Suggested workloads include image sorting, quantum machine learning, and simulation in structural mechanics and meteorology.
Pricing follows the OVHcloud pattern: pay-per-second with no commitment. The 15 emulators start at €0.03 per hour; no per-second rate was published for the Belenos hardware itself.
The quantum revolution accelerates and OVHcloud is taking its part as the European Cloud leader within the ecosystem.
Quandela CEO and co-founder Niccolò Somaschi framed the deal as "a decisive step for quantum in Europe", citing flexibility and sovereign infrastructure as the selling points.
The announcement sits within a broader European pattern: cloud providers stitching together domestic quantum hardware into sovereign-branded services as an answer to US hyperscalers doing the same with Rigetti, IonQ and Quantinuum. For most enterprise buyers, the practical difference today is access — OVHcloud now offers two QPUs and fifteen emulators behind one billing relationship — not compute breakthrough. That changes when error-corrected logical qubits arrive at scale. Belenos is a step on that path, not the destination.
