Quobly and Inria Partner on Integrated, Scalable Silicon Qubit Architecture

Insider Brief

• Quobly and Inria have formed a strategic partnership to co-develop a fully integrated, scalable quantum computing architecture based on silicon qubits and advanced control software.
• The collaboration focuses on middleware and error correction protocols tailored to silicon-based quantum hardware, aiming to bridge the gap between physical qubits and quantum algorithms.
• This partnership supports France’s national Q-Loop program and aligns with Quobly’s industrial roadmap, including its recent launch of a quantum emulator deployed on OVHcloud.

PRESS RELEASE — 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.

“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.
