OVHcloud puts real quantum computer on its cloud, European businesses can now actually use it

Quantum computing has a credibility problem that has nothing to do with the science. The technology works well enough in controlled settings, but for most businesses, it has never felt like something they could realistically touch. OVHcloud is chipping away at that gap by adding Quandela’s Belenos photonic quantum computer to its cloud Quantum Platform, with billing that runs pay-as-you-go rather than demanding long-term commitments or dedicated hardware investments.

Belenos carries 12 qubits and runs from the CEA’s Très Grand Centre de Calcul in France. Quandela first showed it publicly in May 2025, and the numbers behind it are worth noting: the system delivers 4,000 times more computing power than its predecessor. That jump matters because it moves Belenos from an interesting research object into something with practical reach. Organizations can point it at image sorting and generation tasks, accelerated AI calculus, and quantum machine learning workloads, all areas where quantum approaches could eventually outpace classical methods for specific problem types.

Quandela is not standing still on the hardware side either. The company expects to double Belenos’s qubit count by 2026 and targets 40 qubits within three years, which means organizations building familiarity with the system now are positioning themselves ahead of meaningful capability jumps rather than catching up after the fact.

OVHcloud launched its Quantum Platform in November 2025 with plans to host eight quantum computers. Belenos joins the Pasqal Orion Beta QPU, which runs on 100 neutral atom qubits, along with 15 quantum emulators that let developers test algorithms before running them on actual quantum hardware. That pairing of emulators with real QPUs closes a practical gap that has slowed quantum experimentation, teams can build and validate before they spend on actual quantum compute time.

Niccolò Somaschi, CEO of Quandela, put the shift plainly, describing Belenos on OVHcloud as turning a research asset into something concrete that businesses can genuinely build on. For European organizations specifically, the sovereign infrastructure dimension carries real operational weight. Running quantum experiments on European cloud infrastructure removes the jurisdictional friction that has kept regulated industries on the sidelines of quantum development longer than their interest in the technology would otherwise suggest.

OVHcloud R&D director Miroslaw Klaba described the addition as part of Europe staking its position in a quantum ecosystem that is accelerating faster than most observers expected even two years ago.
