Quobly has raised €115 million in Series A funding, in one of Europe's larger quantum hardware financings.
The French quantum computing company will use the investment to support research and development, industrialisation and international commercial expansion as it prepares to launch its first commercial system, Alloy Pioneer, by the end of 2026.
The round was led by Bpifrance, SEALSQ and STMicroelectronics, with participation from the European Innovation Council, Blast, ALIAD and Innovacom. Existing shareholders include CEA, CNRS, Quantonation and Supernova Invest.
Alloy Pioneer is aimed at early adopters in high-performance computing and research. Quobly plans to make the system available through the cloud before deploying it inside HPC infrastructure.
The fundraising follows a €19 million seed phase between 2023 and 2025, during which the company said it proved silicon qubits could be developed within semiconductor manufacturing processes and combined into a broader system architecture.
Industrial push
Founded in Grenoble in 2022, Quobly is developing silicon-based quantum computers using FD-SOI technology on 300 mm wafers. Its approach is intended to address scalability, yield and reproducibility by relying on established semiconductor manufacturing methods.
It is also working with semiconductor and industrial groups including STMicroelectronics, Air Liquide, Soitec and Orano. Those partnerships are intended to support process control, materials engineering, cryogenics and yield optimisation as Quobly moves towards larger-scale production.
The company has more than 100 employees and offices in Singapore and Canada. Its strategy is to fit quantum systems into existing computing environments rather than require bespoke installations. Quobly says its systems are designed to meet current data-centre and HPC requirements for footprint, power supply and utilities.
Access to the first machine will be through Alloy Forge, Quobly's development environment for quantum applications. This is intended to let users develop and test applications under hardware constraints that mirror real systems.
Investor backing
The investor line-up reflects a mix of public and industrial support. Bpifrance is investing through its Deep Tech 2030 fund, which it manages on behalf of the French government as part of the France 2030 initiative.
The presence of STMicroelectronics and Air Liquide's venture arm also highlights the importance of manufacturing and supply-chain expertise to Quobly's model. Across Europe and the US, quantum computing companies have increasingly focused on moving from laboratory demonstrations to repeatable production and commercial systems.
Chief Executive Officer and Co-Founder Maud Vinet outlined the company's next phase. “This financing marks a transition from technology validation to industrial execution. Over the past two years, we have demonstrated that silicon qubits can be developed within semiconductor manufacturing processes and integrated into a system architecture. With this Series A, we are accelerating the deployment of our first commercial systems and building a quantum computing platform designed to integrate into existing computing infrastructures. Our objective is to make quantum computing deployable, scalable and usable within real industrial environments,” Vinet said.
STMicroelectronics framed its investment around manufacturability and links to existing chip production. “Quantum computing will achieve the scale needed by HPC customers only if breakthrough quantum systems can be industrialized and integrated with semiconductor-grade rigor and backed by a robust ecosystem. We are leveraging years of shared expertise in FD-SOI and deep technological collaboration to accelerate the commercialization of Quobly's products thanks to a 300mm silicon fab environment. ST's investment in Quobly further demonstrates our commitment to support its global ambitions,” said Laurent Malier, Executive Vice President, Global Technology R&D, STMicroelectronics.
Bpifrance said the investment also fits a broader European technology agenda. “Our second investment in Quobly is fully in line with our ambition to support the emergence of sovereign technology champions. By choosing a quantum architecture compatible with established microelectronics industry standards, Quobly paves the way for the rapid and controlled industrialization of breakthrough technologies, an essential condition to ensure Europe's strategic autonomy in quantum computing,” said Gwenaël Hamon, Senior Investment Director, Bpifrance.
SEALSQ linked its backing to an existing technical relationship with Quobly. “SEALSQ is proud to participate as a lead investor in Quobly's Series A financing. This investment builds on the technical partnership initiated in 2025. By combining Quobly's silicon-based quantum processors with SEALSQ's post-quantum security technologies, this collaboration contributes to the development of secure quantum computing systems. It supports the development of trusted quantum systems for industrial and critical applications,” said Carlos Moreira, Chief Executive Officer, SEALSQ.
