OVHcloud accelerates the European quantum industry with Quandela’s Belenos

Roubaix – April 17th 2026 – At the Quantum Defence Summit, OVHcloud, a global cloud player and the European Cloud leader, and Quandela, a photonic quantum computing specialist, announce the availability of the Belenos computer on OVHcloud’s Quantum platform.

Unveiled last autumn, the OVHcloud Quantum Platform makes quantum computing, a breakthrough technology, more accessible through a Quantum-as-a-Service (QaaS) consumption model. With the addition of Belenos, OVHcloud continues to deploy its ambitious roadmap of quantum computers accessible through the cloud. 

Quandela Belenos leverages photonic quantum technology to offer a compute power of 12 qubits. It helps organisations to experiment with new algorithms in innovative domains such as image sorting and generation, accelerated AI calculus, or quantum machine learning (QML). New use cases in the fields of electromagnetic simulation, structural mechanics, engine combustion, material simulation, meteorology, and earth observation also benefit from the advances in quantum computing.

Supporting the European quantum ecosystem since 2022, the Group offers the widest range of quantum emulators leveraging its infrastructures with over a thousand users. With 15 affordable quantum emulators (including Perceval and MerLin) starting at 0.03 euros per hour, the Group helps users to grow their familiarity with different quantum computing models. 

“We are delighted to deliver on the promise of the Quantum Platform by adding a second reference quantum computer, Belenos from the French company Quandela. The quantum revolution accelerates and OVHcloud is taking its part as the European Cloud leader within the ecosystem,” said Miroslaw Klaba, R&D Director OVHcloud.

The OVHcloud Quantum Platform gives access to full-fledged quantum computers, to support the acceleration and growing adoption of quantum computing within private organisations. The Belenos QPU is offered in a “as-a-service” mode and benefits from a pay-as-you-go billing with billing per second without commitment. 

“The integration of Belenos 12 qubits into the OVHcloud portfolio marks a decisive step for quantum in Europe. Accessible through the cloud, this photonic computer becomes a concrete tool for businesses. With OVHcloud we are offering data scientists and innovators alike the mean to develop their algorithms on a flexible and sovereign infrastructure” said Niccolò Somaschi, CEO and co-founder Quandela.
