Quobly and Inria combine their expertise to structure a sovereign quantum sector and accelerate scalability
Grenoble / Le Chesnay-Rocquencourt, July 17, 2025 – Quobly, a pioneer in quantum microelectronics, and Inria, France’s national institute for research in digital science and technology, announce a strategic partnership to align silicon-based quantum hardware with advanced control software. This alliance aims to structure a sovereign value chain by combining software excellence with hardware engineering. By expanding its R&D to include low-level software layers – such as those found in embedded, industrial, and operating systems – Quobly reaffirms its ambition to build a fully integrated, fault-tolerant, and scalable quantum computing architecture.
Structuring software development for large-scale quantum computing
Through this partnership, Quobly and Inria are launching a joint effort focused on extending development into the low-level software layer known as middleware – the critical link between physical qubits and quantum algorithms. By combining their expertise, the two organizations aim to develop an integrated quantum computing stack where hardware and software are designed in coherence, to meet the key challenge of scaling up.
Their collaboration will focus on the co-design of robust quantum error correction protocols and middleware specifically tailored to the unique characteristics of silicon-based qubits. This approach paves the way for real-world applications in areas such as complex systems modeling, optimization, chemistry, materials science, and pharmaceutical innovation.
Supporting the emergence of sovereign solutions
This partnership strengthens the national quantum innovation ecosystem, bringing together start-ups, public research laboratories, and industry stakeholders around national and European initiatives. Both partners are actively involved in the national Q-Loop program, launched in September 2024 and funded by France 2030, jointly coordinated by CEA and Inria. The program aims to advance error correction technologies on hardware platforms available in France, with the broader ambition of building French and European leadership in quantum computing.
This new partnership also reflects the shared commitment of both institutions to contribute to Europe’s strategic thinking through white papers and coordinated actions.
A partnership aligned with a controlled industrialization roadmap
This initiative is fully consistent with Quobly’s industrial roadmap, recently marked by the launch of a “perfect” quantum emulator in June 2025, deployed on OVHcloud. This first milestone in an evolving software suite enables the testing of algorithms designed for silicon qubits, in preparation for scaling up Quobly’s future quantum computer.
To support this growth and ensure coherence between software development, hardware constraints, and industrial objectives, Quobly has expanded its software engineering teams.
Partnership signature between Quobly and INRIA, 2025
“This partnership with Inria marks a major step in our ambition to develop integrated quantum computing systems, where hardware and software are co-designed to address the crucial challenge of scaling up. By opening our R&D to middleware, we strengthen our industrial strategy and reinforce our ability to deliver fault-tolerant quantum solutions ready to tackle real-world industrial and scientific challenges,“
said Maud Vinet, Quobly co-founder and CEO.
“Our partnership with Quobly is part of our broader commitment to supporting the emerging French quantum industry. By combining our strengths, we are helping to build a sovereign quantum value chain, from hardware to software, to accelerate the development of robust, high-performance quantum systems that are essential to Europe’s competitiveness in this strategic field,“
added Bruno Sportisse, Inria Chairman and CEO.

About Quobly
Quobly is a pioneer in quantum microelectronics. The company is developing a quantum chip on silicon using the existing industrial semiconductor manufacturing process. Founded in 2022, the company draws on 15 years of collaborative research between internationally renowned Research and Technology Organizations (RTO), CEA-Leti and CNRS. Based in Grenoble, Quobly was co-founded by Maud Vinet, Ph.D. in quantum physics, author or co-author of over 300 papers and holder of more than 70 nanotechnology-related patents, Tristan Meunier, a world-renowned expert in semiconductor quantum engineering, trained under Serge Haroche, winner of the 2012 Nobel Prize in Physics, and François Perruchot, PhD in solid-state physics, engineer, expert in sensor development, modeling and characterization of MEM micro-sensors. Quobly has signed several strategic and operational partnerships with Soitec, Orano, Air Liquide and recently with STMicroelectronics to accelerate the manufacturing process of its “silicon quantum chip”. In 2023, Quobly raised €19 million, setting a new record for seed financing for a European start-up in the quantum sector. In 2025, Quobly obtained a €21 million funding package for its Q100T project.
