Quandela et OVHcloud annoncent un partenariat visant à rapprocher l’intelligence artificielle et l’informatique quantique autour de MerLin, l’environnement de machine learning quantique développé par Quandela. Cette collaboration permet aux chercheurs et aux entreprises de concevoir et simuler des modèles hybrides sur GPU, avant de les tester sur les ordinateurs quantiques photoniques de Quandela, accessibles via la plateforme cloud d’OVHcloud.
Paris et Roubaix — 25 novembre 2025 — Quandela, spécialiste européen de l’informatique quantique photonique, et OVHcloud, acteur majeur du cloud en Europe, annoncent que MerLin (premier environnement dédié au machine learning quantique) sera disponible sur la plateforme OVHcloud à partir de mi-2026. Cette intégration vise à accélérer le développement d’applications hybrides dans un environnement cloud souverain.
Un pont entre IA et quantique
Présenté à l’été 2025, MerLin s’impose comme une brique technologique clé pour une nouvelle génération d’outils de machine learning quantique (QML), compatibles avec des frameworks d’IA tels que PyTorch ou scikit-learn.
Grâce à son intégration dans l’environnement OVHcloud, les utilisateurs peuvent concevoir, simuler et tester des modèles hybrides IA–quantique dans un cadre unifié, s’appuyant sur des GPU NVIDIA.
Cette approche simplifie le passage du prototypage à l’expérimentation : les modèles sont d’abord simulés sur GPU, puis exécutés sur les ordinateurs quantiques photoniques de Quandela, opérés au sein de l’infrastructure OVHcloud.
Une stratégie quantique structurée
Dans le cadre de ce partenariat, OVHcloud a présenté sa stratégie quantique, qui prévoit l’intégration des systèmes de Quandela sur sa plateforme à partir de mi-2026. Les premiers systèmes incluront BELENOS (processeur photonique de 12 qubits) et CANOPUS (24 qubits).
Ce déploiement marque une étape clé dans l’intégration du calcul quantique au cloud, en ouvrant la voie à un accès souverain et opérationnel à l’échelle européenne.
Vers un écosystème quantique européen
En combinant leurs expertises — photonique et algorithmes hybrides pour Quandela, infrastructure cloud pour OVHcloud, accélération via GPU — les partenaires contribuent à structurer un écosystème quantique européen.
L’objectif est d’accélérer le développement d’applications hybrides dans des secteurs tels que la cybersécurité, la finance, l’énergie, la santé ou encore la logistique.
À l’occasion de l’IEEE Quantum Week 2026, qui se tiendra du 13 au 18 septembre à Toronto, Quandela présente une approche permettant d’intégrer progressivement le calcul quantique aux infrastructures d’IA et de calcul haute performance (HPC) existantes, grâce à la technologie NVIDIA NVQLink. Dans cette approche, le GPU reste au cœur du workflow d’IA, tandis que le processeur quantique (QPU) vient le compléter comme un accélérateur spécialisé pour certains workloads.
Paris, 14 septembre 2026 – Après avoir annoncé en juin la validation technique d’une intégration à faible latence entre une infrastructure de calcul accéléré NVIDIA AI et un QPU photonique de Quandela, les deux entreprises publient aujourd’hui un livre blanc technique commun qui présente leur vision et une approche architecturale pour intégrer progressivement le calcul quantique aux infrastructures d’IA et de HPC existantes.
Cette approche repose sur la complémentarité des CPU, GPU et QPU. Le CPU orchestre les workflows, tandis que le GPU reste au centre des traitements d’IA, en prenant notamment en charge les calculs intensifs et la simulation. Le QPU intervient comme un accélérateur spécialisé pour les workloads pour lesquels le calcul quantique pourrait apporter une valeur significative.
Grâce à NVIDIA CUDA-Q (plateforme de programmation ouverte dédiée au supercalcul combinant technologies quantiques et GPU) et NVIDIA cuQuantum (un SDK optimisé pour simuler des calculs quantiques sur des GPU) de NVIDIA, les algorithmes peuvent être développés, simulés et testés sur GPU avant d’être exécutés sur un QPU photonique réel. NVQLink permet quant à lui d’établir une connexion à faible latence entre l’environnement GPU NVIDIA et le Quantum System Controller, qui contrôle ensuite le QPU.
Les organisations peuvent ainsi explorer progressivement les applications quantiques en s’appuyant sur leurs infrastructures de calcul existantes, sans avoir à remplacer leurs environnements actuels.
Une avancée vers un calcul quantique plus accessible
Cette collaboration vise à faciliter l’intégration du calcul quantique dans les environnements d’IA et de HPC existants. Les utilisateurs peuvent ainsi expérimenter, développer et tester des applications quantiques à partir de leurs workflows de calcul habituels.
L’objectif est notamment d’identifier les workloads pour lesquels le calcul quantique pourrait apporter une valeur significative et de faire émerger progressivement les applications les plus pertinentes.
La collaboration s’inscrit dans une démarche en trois étapes : Access, Integration & Discovery et Scale.
Access permet aux chercheurs et aux organisations de découvrir et d’expérimenter le calcul quantique sans disposer de leur propre infrastructure.
Integration & Discovery consiste à intégrer le QPU aux environnements CPU et GPU existants afin de développer, simuler et tester différents algorithmes, et d’identifier les workloads pour lesquels le calcul quantique pourrait être particulièrement pertinent.
Scale vise à faire évoluer les applications ayant démontré leur potentiel vers des systèmes quantiques plus importants et performants.
Cette approche permet aux utilisateurs de progresser étape par étape vers le calcul quantique, en capitalisant sur leurs infrastructures existantes et en développant de nouvelles capacités au fur et à mesure que des applications à fort potentiel sont identifiées.
Une architecture présentée à l’IEEE Quantum Week
L’architecture développée par Quandela en s’appuyant sur les technologies NVIDIA sera présentée lors de l’IEEE Quantum Week 2026 à Toronto le 17 septembre matin sur le stand de NVIDIA (#600).
À cette occasion, les équipes de Quandela échangeront avec les visiteurs sur l’intégration des QPUs photoniques dans les infrastructures d’IA et de HPC et présenteront la publication commune consacrée à cette nouvelle architecture hybride, qui associe les capacités de calcul des GPU et des QPUs.
La vidéo ci-dessous illustre le fonctionnement de cette nouvelle architecture hybride entre calcul classique et quantique :

Quandela publie sa nouvelle vision pour intégrer les QPU aux infrastructures d’IA et de calcul haute performance avec NVIDIA NVQLink

For IEEE Quantum Week 2026, held in Toronto from September 13 to 18, Quandela is showcasing an approach to progressively integrating quantum computing into existing AI and high-performance computing (HPC) infrastructures with NVIDIA NVQLink. In this approach, the GPU remains at the core of the AI workflow, with the quantum processor (QPU) acting as a specialized accelerator for specific workloads.
Paris, September 14, 2026 – Building on our June announcement of a low-latency integration between a Quandela photonic QPU and NVIDIA AI infrastructure, the companies are publishing a technical white paper today. This paper outlines a vision and architectural framework for gradually integrating quantum computing into current AI and HPC environments.
This approach is based on the complementarity of CPUs, GPUs and QPUs. The CPU orchestrates workflows, while the GPU remains at the center of AI processing, notably handling intensive computation and simulation. The QPU acts as a specialized accelerator for workloads for which quantum computing could bring significant value.
Thanks to the NVIDIA CUDA-Q platform (an open quantum-GPU supercomputing programming platform) and NVIDIA cuQuantum (an SDK optimized for simulating quantum computations on GPUs), algorithms can be developed, simulated and tested on GPU before being run on an actual photonic QPU. NVIDIA NVQLink enables a low-latency connection between the NVIDIA GPU environment and the Quantum System Controller, which then controls the QPU.
Organizations can thus progressively explore quantum applications by relying on their existing computing infrastructure, without having to replace their current environments.
A step toward more accessible quantum computing
By facilitating the integration of quantum computing into current AI and HPC environments, this platform empowers users to experiment, develop, and test quantum applications directly from their standard workflows.
The primary goal is to identify workloads where quantum computing can deliver significant value and progressively bring the most relevant applications to light.
The collaboration follows a three-step approach: Access, Integration & Discovery, and Scale.
Access allows researchers and organizations to discover and experiment with quantum computing without having their own infrastructure.
Integration & Discovery involves integrating the QPU into existing CPU and GPU environments to develop, simulate and test various algorithms, and to identify the workloads for which quantum computing could be particularly relevant.
Scale aims to scale up applications that have demonstrated their potential toward larger, more powerful quantum systems.
This approach allows users to progress step by step toward quantum computing, building on their existing infrastructure and developing new capabilities as high-potential applications are identified.
An architecture presented at IEEE Quantum Week
The architecture developed by Quandela building on NVIDIA technologies will be presented at IEEE Quantum Week 2026 in Toronto on the morning of September 17, at the NVIDIA booth (#600).
At the event, Quandela’s teams will discuss the integration of photonic QPUs into AI and HPC infrastructures with visitors and present their joint publication on this new hybrid architecture combining GPU and QPU computing capabilities.
Watch the video to understand how this new hybrid architecture between classical and quantum computing works:
Jean Senellart, Chief Technology and Product Officer at Quandela states:
“The challenge is no longer just about accessing a QPU, but about integrating it directly into AI workflows. With NVIDIA, we are opening a path where the photonic QPU becomes a specialized accelerator for exploring and validating hybrid algorithms, particularly in QML, before scaling the most promising use cases.”
Sam Stanwyck, Director of Quantum Product at NVIDIA says:
“Quantum computing becomes more useful when it moves beyond standalone access and becomes part of the accelerated computing researchers already use. Our work with Quandela provides a step-by-step model for bringing photonic QPUs into NVIDIA quantum-GPU supercomputing, helping teams identify promising applications today and scale them as more powerful systems come online.”

Announced during the Vietnam–France Leaders Forum, in presence of Vietnamese General Secretary and President Tô Lâm and French President Emmanuel Macron, the agreement combines Quandela’s full-stack photonic quantum computing platform with Quanova’s local integration capabilities, backed by strategic investment from Nam A Bank, to develop talent, infrastructure and concrete quantum use cases in Vietnam.
Paris, 11 September 2026 – Quandela, a European leader in photonic quantum computing, and Quanova, a Vietnamese quantum technology and ecosystem development company, announce the signing of a strategic partnership agreement aimed at supporting the long-term development of quantum computing capabilities in Vietnam.
The agreement was formalized during the Vietnam–France Leaders Forum, held in the presence of French President Emmanuel Macron and General Secretary and President of Vietnam Tô Lâm as part of his official visit to France.
Under the agreement, Quanova will act as a strategic integrator for Quandela in the Vietnamese market. The two companies will work together to promote, develop and commercialize solutions based on Quandela’s photonic quantum computing technology.
Their collaboration will include the training of Quanova’s technical and commercial teams, the development of joint offerings, customer engagement and demonstrations, and the identification of relevant use cases with Vietnamese universities, research organizations and businesses.
“Vietnam is emerging as one of Southeast Asia’s most dynamic quantum ecosystems. Our ambition is to help turn this momentum into lasting capabilities: trained talent, access to photonic quantum computing and concrete projects for universities, research institutions and businesses,” said Niccolo Somaschi, co-founder and CEO of Quandela. “Quanova’s strong local roots and expertise as a strategic integrator make it the right partner to build this bridge with us.”
The agreement builds on several initiatives already undertaken by Quandela and its Vietnamese partners. With Quanova and other local stakeholders, Quandela recently supported a quantum hackathon organised by VNQuantum and the province of Gia Lai, focused on applications connected to Vietnam’s development priorities.
One of the first concrete initiatives supported by the partnership with Quanova is the quantum technology training programme at Quang Trung University, backed by Nam A Bank as a strategic investor. The programme aims to train students and researchers while expanding their access to quantum computing capabilities.
“Vietnam’s opportunity in quantum will be built through real capabilities: trained teams, access to world-class platforms and projects connected to local needs,” said RossyNguyen Hoang Hong Nhung, CEO of Quanova. “Working with Quandela will help Vietnamese organizations move from initial exploration to concrete applications, while strengthening the national ecosystem for the long term.”
The two companies also share the ambition of preparing for the future deployment of a photonic quantum computer in Vietnam. Their approach is based on ensuring that any future infrastructure is supported by the skills, software and local ecosystem required to use it effectively and create long-term value.
The agreement signed in Paris provides a framework for developing joint offerings and new opportunities with Vietnamese stakeholders. Quandela and Quanova expect to announce further concrete steps in the coming months.

Established in Canada, Quandela’s photonic quantum computer is the only device of its kind available to companies participating in this Canada-wide research and development program.
MONTREAL, September 2, 2026 – Quandela, a leading player in photonic quantum computing technologies, has signed a memorandum of understanding with CMC Microsystems to join the Quantum Computing Sandbox as a provider of cloud-based computing services. Quandela’s expertise, based within the country, now joins forces with other providers to offer a comprehensive suite of quantum options made available to small and medium-sized enterprises, organizations, and academic researchers, with the aim of developing and accelerating the solutions that will be applied to a wide range of fields and needs.
“As data sovereignty in the digital realm becomes an increasingly important issue given the current global context, we are proud to be the first to include a Canada-based photonic quantum computer among the cloud computing options available to the participants of the QCS program”, stated physicist Valérian Giesz, Co-Founder and Director of Strategic Partnerships at Quandela. “This will allow their work and data to be entirely hosted on Canadian soil, without having to go through a structure located in another country.”
The Quantum Computing Sandbox (QCS) is supported by FABRiC, an organization funded by Innovation, Science and Economic Development Canada (ISED), whose mission is to build an ecosystem which strengthens Canada’s semiconductor sector. QCS’ role, through technical support and research grants, is to foster the development of quantum applications for Canada’s various industrial sectors and fields of activity, including national and strategic projects. CMC Microsystems is the nonprofit organization responsible for managing FABrIC on behalf of the Government of Canada; its mandate is to facilitate affordable access to the tools required for the development of advanced technologies.
Multifaceted support
The memorandum of understanding between Quandela and CMC Microsystems also includes a provision to provide support to companies and organizations whose high-potential projects have been selected, thus granting them access to the Quantum Computing Sandbox. This assistance, which may be both technical and practical in nature, will be offered by Quandela in collaboration with CMC Microsystems. The latter is directly involved in selecting the companies eligible for a grant.
As Quandela and CMC Microsystems already have a well-established relationship, the framework of the QCS program will enable the two entities to further share their expertise and experience with companies, organizations, and universities which do not have teams or personnel sufficiently trained in the rules and requirements of quantum computing.
“Since the algorithms used in certain projects perform better on certain specific computing architectures, integrating Quandela as an additional tool further diversifies the options made available to the participants who have access to QCS, whether in terms of research, prototyping, or implementing solutions,” added Valérian Giesz. “This is what makes the QCS model even more attractive to companies looking to invest not only in the development of quantum solutions, but also in the development of quantum computing itself.”
