Belenos, a 12-qubit photonic quantum computer from Quandela, is now commercially available on OVHcloud’s public cloud through its Quantum-as-a-Service platform.
OVHcloud said hosting the system in European data centers gives enterprises sovereign access outside the reach of the U.S. CLOUD Act, aiming to reduce IP leakage and compliance risks.
Quandela’s processor uses photons as qubits and runs its core operations at room temperature, unlike many rival approaches that depend on near-absolute-zero cooling.
OVHcloud said users can develop and validate code on 15 quantum emulators—starting at €0.03 per hour—before moving workloads to the physical QPU under per-second, pay-as-you-go billing.
The launch extends OVHcloud’s quantum sandbox built since 2022 and targets early machine-learning, simulation, structural mechanics and earth-observation workloads.
Is Europe's sovereign quantum cloud a true tech leap or just a strategic shield against U.S. data laws?
Can a 12-qubit machine deliver real business value now, or is its main purpose asserting digital autonomy?
OVHcloud and Quandela Unveil 12-Qubit Belenos Quantum Computer on Cloud, Advancing European Quantum Leadership
Overview
On June 17, 2026, OVHcloud expanded its Sovereign Quantum-as-a-Service platform by integrating Quandela’s Belenos, a 12-qubit photonic quantum computer. This move made advanced quantum computing globally accessible to researchers, businesses, and industries, while lowering the barrier for experimenting with real quantum hardware. By offering sovereign quantum access, OVHcloud aims to foster a strong European quantum ecosystem and reduce reliance on non-European providers. The integration of Belenos marks a new era for cloud quantum access, supporting innovation and making powerful quantum resources available to a wider audience.
