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 its 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. 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."

The memorandum extends beyond access; it includes provisions for supporting high-potential projects selected for the Sandbox, granting them direct access to Quandela's photonic quantum computer. The authors state this model attracts companies investing not only in quantum solutions but also in the development of quantum computing itself. Quandela validates low-latency photonic QPU & NVIDIA AI integration. Results presented at ISC 2026 detailed the integration of a Quandela photonic quantum processing unit with an NVIDIA GPU host and an FPGA-based Quantum System Controller via NVIDIA's NVQLink. This connection moves beyond remote quantum access, suggesting a future where photonic QPUs can be installed on-premise or in dedicated data centers and directly linked to existing accelerated computing infrastructure. This architecture provides both hardware and software for low-latency, real-time communication between GPU supercomputing infrastructure and quantum system controllers, enabling a new execution model for hybrid quantum-classical computing. The company's approach focuses on incremental progress, having deployed industrial systems since 2023 and developing scalable, fault-tolerant quantum computers through the integration of thousands of photonic components, the company says. "Tightly integrating quantum systems with accelerated computing is proving hugely impactful for quantum research," said Sam Stanwyck, Director of Quantum Product at NVIDIA. Beyond research applications, this integration addresses the needs of HPC centers, sovereign AI and quantum programs, and industrial users seeking on-site quantum acceleration. According to the company, the validation suggests future NVQLink-enabled deployments. "Quandela's work with NVQLink shows how quantum-GPU supercomputing systems will fundamentally transform how we are able to think about computing applications when information can be passed seamlessly between different processors," Stanwyck added. Since the algorithms used in certain projects perform better on specific computing architectures, integrating Quandela as an additional tool further diversifies the options available to participants in the Canada-wide research and development program, whether for research, prototyping, or solution implementation. This is a step toward a future where quantum processing can be seamlessly integrated into existing computational workflows. Quantum Computing Sandbox supports Canadian Innovation & data sovereignty. A strategic partnership signed June 18th, 2026, at the Franco-Gulf economic forum coincides with this expansion, strengthening Quandela's presence in Qatar. The memorandum of understanding between the two companies focuses on deploying quantum computing solutions tailored to Gulf markets, positioning both as early adopters of the technology in the region. According to the company, Mekdam Holding Group reported revenues of QAR 681.1 million (€161 million) and an order backlog of QAR 3.1 billion (€734 million) in 2025. The partnership aligns with Qatar National Vision 2030 and national strategies for digital sovereignty and artificial intelligence across Gulf countries, indicating a regional commitment to emerging technologies.

Key technology for photonic quantum processor units: Paderborn University coordinates new collaborative project. 04.09.2026 | Research, Transfer, Quantum Computation, Press release, Institute for Photonic Quantum Systems (PhoQS), Faculty of Science, Department of Physics Quantum technologies in Germany are making enormous strides, particularly in computing, communications, and sensor technology. However, researchers and developers face many technical and geopolitical challenges in the development and further advancement of these technologies. Through the funding scheme 'Enabling Technologies for Resilient R&D Supply Chains in Quantum Technologies', the Federal Ministry of Research, Technology and Space (BMFTR) is funding pre-competitive collaborative projects focused on the development and further advancement of fundamental technologies for quantum computers and quantum sensors. Coordinated by Paderborn University, the collaborative project 'Detector Engineering to Enable Quantum Technology' (DETEQT) has now been launched and will receive funding of around six million euros over a period of three years. Project redefines scalability and interoperability. Photonics-based quantum processor units (QPUs) are indispensable in photonic quantum computing, quantum communication, and sensor technology. Whilst they may offer an advantage over classical components, their functionality is often limited by their single-photon detector systems. The 'DETEQT' project aims to overcome these limitations and holistically further develop QPUs based on so-called single-photon nanowire detectors (SNSPDs). "Although individual SNSPDs can, when considered in isolation, meet the stringent performance criteria required to enable photonic QPUs, it remains a major challenge to maintain this performance when integrated into the QPU at the required scale. As a result, photonic QPUs are currently facing clear limitations, whether due to limited detector efficiency, cryogenic thermal load, low-loss integration with other components, or insufficient photon number resolution, PNR for short. With our project, we aim to overcome these technical hurdles holistically and resolve the issue of poor interoperability. In this way, we are creating the conditions for practical integration," explains Prof. Dr. Tim Bartley, coordinator of the collaborative project and group leader at the Institute for Photonic Quantum Systems (PhoQS) and the Department of Physics at Paderborn University. Strong consortium from academia and industry. This project involves joint research and development by Paderborn University, the Technical University of Munich, the University of Heidelberg, the Physikalisch-Technische Bundesanstalt, Swabian Instruments GmbH, Munich Quantum Instruments GmbH, the Leibniz Institute for Photonic Technologies, Single Quantum Germany GmbH, the University of Münster, Pixel Photonics GmbH, Quandela GmbH and the associated partner attocube systems GmbH. At the same time, the 'Photonics Systems Engineering' cluster is also being launched; this comprises a total of seven collaborative projects under the funding programme and is likewise coordinated by Paderborn University, under the leadership of Prof. Bartley. The cluster represents the combined strength of research institutes, universities, start-ups and small and medium-sized enterprises under a single umbrella brand. This network underscores the strategic importance of photonics as an 'enabling technology' for quantum research, aiming not only to promote knowledge transfer between the collaborative projects but also to build bridges to other projects in the field of quantum technology in Germany.
