Introducing Quandela Cloud 2.0

Quandela, the European-based quantum computing provider, is announcing the release of its new version of its quantum computing cloud service, Quandela Cloud 2.0, providing end-users with the most powerful platform for developing photonic quantum applications

Quandela, the European-based quantum computing provider, is announcing the release of its new version of its quantum computing cloud service, Quandela Cloud 2.0, providing end-users with the most powerful platform for developing photonic quantum applications.

Initially launched in January 2023, and now comprised of hundreds of corporate users, Quandela Cloud is a comprehensive platform to discover, learn, test, and develop quantum solutions. It gives access to the most advanced quantum servers available at Quandela, easy to use software for generating and manipulating quantum circuits, as well as middleware for executing hybrid quantum-classical workflows in heterogeneous computing environments.

For developers, researchers and quantum engineers, this announcement comes with multiple benefits: • Quandela Cloud 2.0 delivers significant improvements in circuit construction, compilation times, and memory consumption compared to the earlier release.

• Perceval, the open-source framework to program photonic quantum computers provides developers with versatile and powerful user tools for mapping circuits to quantum hardware and executing them on simulators or actual QPUs.

• The introduction of new application-centered SDKs and APIs aims to facilitate seamless integration into cloud system dataflow and hybrid computing with classical processors (CPU and GPU) in data center infrastructures.

This release follows the successful launch of two quantum computing systems with cloud providers in Europe and North America. As Quandela continues its path, it remains dedicated to timely deliveries and ongoing technical advancements.

Discover the Key Enhancements in This New Release:

Quantum Toolbox: This comprehensive suite includes pre-optimized primitives tailored for specific applications such as Variational Quantum Eigensolver (VQE) and graph analysis. It expedites the time to production of quantum algorithms for industry-specific use cases, by providing a native optimization of these algorithms with Quandela QPUs and selected GPUs. Backed by the expertise of Quandela’s application team, users will receive direct support to maximize the utility and efficacy of these tools.

Exqalibur – GPU-Enhanced Emulation: Introducing a new emulator for photonic qubits that leverages the capabilities of the most powerful GPU, and enables computations at an unprecedented scale. With this advancement, users can now explore up to 150 billion parameter spaces across 20 photonic qubits at kilohertz rates, facilitating faster prototyping and optimization of quantum algorithms.

Exclusive QPU Reservation Service: In addition to standard on-demand access, the new system offers premium users an intuitive reservation platform to secure QPU time on designated dates and times. This tailored reservation model enhances the user experience by facilitating seamless coordination among development teams.

QPU Advancement – Introducing Altair: With the release of Quandela Cloud 2.0, significant enhancements have been made to the quantum computing hardware. Altair, the latest 10-qubit quantum processor takes central stage and is now accessible to developers worldwide. This upgraded quantum processing unit builds upon the success of its predecessor, Ascella, which was launched in January 2023 and operated for over 12,900 hours. Ascella achieved a remarkable availability rate of 92% over a 6-month operation.

Built-in Error Mitigations: Two powerful patented error mitigation techniques have been introduced for the control of Altair, allowing us to push further the fidelity and quantum gates speed:

• AI-driven Quantum Fidelity Enhancement: This technique harnesses the power of machine learning’s ‘clear-box’ methodology to significantly mitigate hardware imperfections. This innovative approach boosts qubit fidelity by several percentage points, ensuring even greater reliability and performance in quantum computing applications. Further details are provided below.

• Photon Recycling: This unprecedented technique exploits lossy output photon states to consolidate statistics of non-lossy states, allowing for a more precise estimation of the probability distribution with fewer numbers of shots.

Combined with AI-boosted error mitigation software and transpilation technique, Altair reaches fidelities of: 1-qubit gate: 99.94%, and 2-qubit gate: 98.2% and a Q-score of 6.

Quandela and OVHcloud join forces to democratize quantum machine learning with MerLin

×

At the international Adopt AI event in Paris, Quandela and OVHcloud announce a strategic initiative to bring closer AI and quantum computing thanks to MerLin, Quandela’s quantum machine learning environment. This collaboration will enable researchers and companies to prototype and simulate hybrid models on NVIDIA GPUs before testing them on Quandela’s photonic quantum computers, directly accessible from OVHcloud’s cloud platform.

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.
