Paris, Roubaix (France), November 25 2025 -- Quandela, European leader in photonic quantum computing, and OVHcloud, a major European cloud provider, announce that MerLin – the first programming language and environment dedicated to quantum machine learning – will be made available on OVHcloud’s platform starting mid-2026. This unified approach will accelerate the development of hybrid applications within a sovereign cloud environment.

A bridge between AI and quantum

Unveiled in summer 2025, MerLin lays the groundwork for a new generation of Quantum Machine Learning (QML) tools, integrated into standard AI frameworks such as PyTorch and scikit-learn.
Now, thanks to its integration into the OVHcloud platform, users will be able to design, simulate, and test their hybrid AI-Quantum neural networks in a unified cloud environment powered by NVIDIA GPUs, a shared partner of both companies.

This approach will accelerate the development of industrial quantum applications: users will first be able to run their simulations on GPUs, then test and validate their models on Quandela’s photonic quantum computers, hosted and operated within OVHcloud.

A clear quantum roadmap

As part of this partnership, OVHcloud has published its quantum roadmap, announcing that Quandela’s quantum computers will become available on its cloud platform in mid-2026. The first systems to be offered will be BELENOS, a 12-qubit photonic processor, and CANOPUS, a 24-qubit photonic processor.

This deployment will be a major milestone in integrating quantum computing into the cloud, paving the way for democratized and sovereign access to European quantum power.

“This partnership with OVHcloud perfectly embodies our vision: to make quantum accessible and useful for AI experts. With MerLin, we provide a seamless environment – from GPU to quantum processor – allowing the exploration of new hybrid algorithms and accelerating the journey from concept to real-world application,” says Jean Senellart, Chief Product Officer at Quandela.

“With MerLin, data scientists finally have an accessible framework that does not require quantum computing skills – an actual tool that democratizes its use for the most innovative function in companies: data science,” says Fanny Bouton, Quantum Lead and Product Manager at OVHcloud.

Toward a sovereign European quantum cloud

By combining their expertise – photonics and hybrid algorithms for Quandela, cloud and sovereign infrastructure for OVHcloud, GPU acceleration for NVIDIA – the two partners are laying the foundations of a competitive and open European quantum ecosystem. An ecosystem expected to foster the emergence of hybrid applications in fields such as cybersecurity, finance, energy, healthcare, and logistics.
