Paris, November 7th 2023. Quandela, the European leader in photonic quantum
computing, has successfully secured over €50 million from investors, the
French government through the France 2030 Plan, and banking partners. New
investors, Serena, Credit Mutuel Innovation, and the European Innovation
Council Fund, have joined the company’s capital, alongside existing historical
investors, Bpifrance 1, OMNES Capital and Quantonation. Quandela has also
received support from France 2030 as the laureate of the “Première usine” call
for projects, operated by Bpifrance. This capital increase will allow Quandela to
expedite its international expansion and increase the production of its
quantum computers to meet the needs of industrial clients.


Over the past few months, Quandela has achieved several milestones, solidifying its
position as the leading European provider of photonic quantum computing. By the end
of 2022, Quandela became the first player in the European Union, and one of the few
globally, to make its quantum computers accessible via the cloud. Furthermore,
Quandela was the first European supplier to open its quantum computer manufacturing
facility in June 2023, in Massy (France). Today, the first quantum computer produced
in this facility has just been delivered to OVHcloud datacenter. This marks the first
European quantum computer purchased and hosted by an industrial client.


Quandela has already initiated the production of three new machines within its facility,
scheduled for deliveries in 2024. Simultaneously, the company, which already
collaborates with EDF, ONERA and MBDA, continues to develop use cases with
industrial players both in France and abroad.

While already established in Germany, Quandela now aims to solidify its position in
North American and Asian markets. To meet these new challenges, the company plans
to increase its workforce in the coming months.
This fundraising round represents a significant milestone for Quandela, enabling the
acceleration of its growth and support for its international expansion. Quandela will
thus strengthen its presence on the global stage with the objective of supporting an
increasing number of industrial clients in utilizing quantum computing to address ever
more complex use cases.”


“We’re very proud to continue to support the growth of Quandela, which successfully
opened Europe’s first quantum computer production plant a few months ago. This
support is a perfect illustration of the ambitions of Bpifrance’s Deeptech plan: to
encourage the rise of French champions driving breakthrough innovations in the
coming decades.” Paul-François Fournier, Executive Director in charge of
Innovation.


“Many years of R&D have enabled Quandela to converge fundamental and applied
research with the first industrial results, delivering a quantum computer in the cloud as
well as quantum computers for private customers. Over and above the quality of the
teams and the technological depth of their solution, these European – and in some
respects global – innovations have convinced us of the project’s potential and
scalability. The computing power of quantum has become real and accessible.


Structuring the teams and implementing the international roadmap will be among the
value-creating milestones ensuring the project’s success. Supporting projects at the
cutting edge of French know-how, with a strong economic impact and the capacity to
prepare for industrialization, is fully in line with Crédit Mutuel Innovation’s strategy.”
Maxence Valero, VC Investment Director, Crédit Mutuel Innovation.


“Quandela, as a major European player in photonic quantum computing, embodies the
innovation and disruptive potential actively supported by the EIC. This investment
reflects our trust in their capacity to bring about significant change and drive innovation
in the global technological landscape.” Svetoslava Georgieva, Chair of the EIC Fund
Board.


“At Serena, we’re convinced that quantum computing will revolutionize tomorrow’s
world. The choice of photonics, combined with a full-stack quantum architecture, is the
most promising approach we’ve seen to date. Quandela recently reached a new milestone by becoming the first player to have made qubits available in the cloud and to have sold the first machine to an industrial company. We are proud to support this world-renowned team in this phase of internationalization and industrialization.”
Floriane de Maupeou, Senior Associate, Serena.

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.

Quandela Accelerates Quantum Spin-Photon Simulationby 20,000x with NVIDIA CUDA-Q

×

Quandela and NVIDIA have achieved a transformative 20,000x acceleration in quantum photonics simulation using NVIDIA CUDA-Q the GPU-accelerated platform for hybrid quantum-classical computing. This breakthrough dramatically reduces development cycles for quantum optical hardware from months to hours, advancing Quandela’s Spin–Photonic Quantum Computing (SPOQC) architecture for fault-tolerant quantum computing while also creating new opportunities for hybrid quantum–classical computing approaches that combine the strengths of both paradigms.

The advance builds on Quandela’s Zero-Photon Generator (ZPG)method, which reformulates complex photon-mediated dynamics into parallelizable master equations, CUDA-Q’s master equation solver enhanced in v0.12 with support for custom superoperators andbatched Liouvillian evolution, make it possible to run hundreds of open-system simulations simultaneously on a single NVIDIA Hopper GPU, reaching an acceleration of four orders of magnitude compared to existing simulation tools. Together, these advances turn previously intractable light–matter simulations into a real-time engineering tool.

Dr. Jean Senellart, Chief Product Officer of Quandela, said: “This collaboration with NVIDIA represents a paradigm shift in how we approach quantum hardware development. What once took weeks of computation can now be done in minutes, enabling us to explore thousands of design variations and accelerate our roadmap to fault-tolerant photonic quantum processors.

The collaboration demonstrates how GPU acceleration is now redefining quantum research. CUDA-Q v0.12.0 introduces the new superoperator and batching features developed through this joint effort, now publicly available for researchers and developers.

Sam Stanwyck, Group Product Manager for quantum computing at NVIDIA, commented: “Development of larger and more performant quantum hardware requires increasingly more complex simulations. Quandela’s work with CUDA-Q shows how GPU-accelerated simulations are compressing months of quantum hardware development into hours, and accelerating the development of useful accelerated quantum supercomputers.

This milestone sets a new benchmark for simulating distributed spin–photon quantum gates, supporting Quandela’s broader mission to build fault-tolerant photonic quantum processors. Detailed benchmarks and implementation resources are available in the Quandela technical blog.
