French quantum startup backed by CEA, CNRS and STMicroelectronics moves from lab validation to industrial-scale quantum systems
Quobly, a Grenoble-based quantum computing company spun out of French research institutions CEA-Leti and CNRS, has raised €115 million in Series A funding to accelerate the industrialisation of its silicon-based quantum computing platform.
The round marks a transition for the company from technology validation to early commercial deployment, with its first product expected to reach the market by the end of 2026.
Strong industrial backing for semiconductor-based quantum computing
The financing was led by Bpifrance, SEALSQ, and STMicroelectronics, with participation from the European Innovation Council (EIC), Blast, Air Liquide Venture Capital (ALIAD), Innovacom, and existing strategic stakeholders including Quantonation and Supernova Invest.
The investor mix reflects a strong alignment between quantum computing research, semiconductor manufacturing, and European industrial policy—positioning Quobly as part of a broader effort to build sovereign quantum infrastructure in Europe.
Silicon qubits designed for industrial scale
Founded in 2022 by Maud Vinet, Tristan Meunier, and François Perruchot, Quobly is developing quantum computers based on silicon qubits manufactured using standard semiconductor processes.
The company uses FD-SOI technology on 300mm wafers, aiming to leverage existing semiconductor fabrication infrastructure to solve one of quantum computing’s key challenges: scalability and reproducibility.
CEO Maud Vinet described the raise as a shift toward industrial execution:
“We are accelerating the deployment of our first commercial systems and building a quantum computing platform designed to integrate into existing computing infrastructures.”
From research spin-out to quantum hardware platform
Quobly originated as a spin-off from French public research institutions and has since positioned itself as an industrial-first quantum computing company focused on manufacturability and system integration.
Its approach emphasizes tight collaboration with semiconductor and materials partners including STMicroelectronics, Air Liquide, Soitec, and Orano to ensure compatibility with industrial fabrication, cryogenics, and yield optimisation processes.
First commercial system: Alloy Pioneer
The company is preparing to launch its first product line, Alloy Pioneer, targeted at early adopters in high-performance computing and research environments.
The system will initially be accessible via the cloud in 2026, with deeper integration into HPC infrastructures planned for 2027. Customers will also use Quobly’s development environment, Alloy Forge, to build and test quantum applications under realistic hardware constraints.
Industrialisation as the core strategy
Unlike many quantum startups focused primarily on experimental prototypes, Quobly is explicitly targeting integration into existing HPC and data-centre environments, ensuring compatibility with industrial power, footprint, and infrastructure standards.
STMicroelectronics highlighted the importance of semiconductor-grade manufacturing discipline in scaling quantum systems, reinforcing the company’s strategy of bridging quantum research and industrial production.
