Grenoble, FranceJune 4, 2026 /PRNewswire/ — French quantum computing company Quobly today announced the completion of a €115 million Series A funding round, aimed at accelerating the industrialization of its silicon-based quantum computer and planning to bring its first commercial product to market by the end of 2026.
- This round is led by Bpifrance, SEALSQ, and STMicroelectronics, with participation from the European Innovation Council (EIC), Blast, ALIAD (Air Liquide Venture Capital), and existing investor Innovacom, bringing together top-tier investors from industrial, sovereign, and deep tech sectors. Existing shareholders also include CEA, CNRS, Quantonation, and Supernova Invest.
Long-term investor Bpifrance is participating through the Deep Tech 2030 fund, managed by Bpifrance on behalf of the French government as part of the France 2030 initiative. - This funding will support ongoing research and development, industrialization efforts, and international business expansion.
- Quobly is committed to applying semiconductor-grade manufacturing and industrialization technologies to quantum computing, planning to deploy its first commercial quantum computer via the cloud by the end of 2026 through its Alloy product line.
Quobly Series A Funding – Leadership Team
From Technology Validation to Large-Scale Commercial Deployment
This Series A funding marks a critical step for Quobly on its path toward industrial-grade quantum computing, transitioning from the early validation phase to the mass production of its first commercial systems.
Alloy Pioneer, the first computer in Quobly’s Alloy product line, is designed for early adopters in high-performance computing (HPC) and research environments. The system will be accessible via the cloud in 2026, followed by deployment in HPC infrastructure in 2027.
Quobly’s quantum computer is designed to seamlessly integrate with existing HPC and data center infrastructure, with footprint, power, and utility requirements compatible with current systems for easy deployment.
Users can access Alloy Pioneer through Quobly’s quantum application development environment, Alloy Forge, enabling them to develop and validate applications under real hardware constraints.
The company will focus on:
- Enhancing the performance and scalability of its quantum computer product line,
- Accelerating the industrialization and volume production of its silicon-based quantum processors,
- Deploying its first Alloy systems into customer cloud and HPC environments.
Quobly will continue to expand its hardware, control electronics, and software stack to support these efforts, in line with its system-level co-design approach.
Scaling Quantum Computing Through Semiconductor Manufacturing
Quobly’s technical approach is based on applying FD-SOI technology on 300mm wafers, leveraging mature semiconductor manufacturing processes to address key challenges in scalability, yield, and reproducibility. The company is dedicated to developing silicon qubits, aiming for high-density integration and compatibility with industrial manufacturing standards.
As part of this strategy, Quobly leverages semiconductor-grade technical capabilities within the broader semiconductor ecosystem through strategic partnerships with industry leaders such as STMicroelectronics, Air Liquide, Soitec, and Orano. These collaborations will accelerate the transfer of Quobly’s quantum technology into advanced manufacturing environments, driving the industrial integration of process control, materials engineering, cryogenics, and yield optimization from the earliest stages of deployment.
This industry-first approach sets Quobly apart, with its core focus on prioritizing manufacturability and the co-development of technology and systems.
Executive Summary
Maud Vinet, CEO and Co-founder of Quobly, said:
“This funding round marks the company’s transition from the technology validation phase to the industrialization implementation phase. Over the past two years, we have demonstrated that silicon qubits can be developed using semiconductor manufacturing processes and integrated into system architectures. With this Series A funding, we will accelerate the deployment of our first commercial systems and build a quantum computing platform designed to seamlessly integrate with existing computing infrastructure. Our goal is to make quantum computing deployable, scalable, and applicable in real industrial environments.”
Investor Perspectives
Laurent Malier, Executive Vice President of Global Technology R&D at STMicroelectronics, said:
“Quantum computing can only reach the scale required by high-performance computing (HPC) customers when breakthrough quantum systems are industrialized and integrated with semiconductor-level rigor, supported by a robust ecosystem. Leveraging years of shared expertise in FD-SOI and deep technical collaboration, we are accelerating the commercialization of Quobly’s products using 300mm silicon fab environments. ST’s investment in Quobly further underscores our commitment to supporting its global growth ambitions.”
Gwenaël Hamon, Senior Investment Director at Bpifrance, said:
“Our second investment in Quobly fully aligns with our vision of supporting the rise of local tech leaders. By choosing a quantum architecture compatible with existing microelectronics industry standards, Quobly paves the way for the rapid and controlled industrialization of breakthrough technology, a necessary condition for ensuring Europe’s strategic autonomy in quantum computing.”
Carlos Moreira, CEO of SEALSQ, said:
“SEALSQ is honored to participate as a lead investor in Quobly’s Series A round. This investment builds on a technical collaboration launched in 2025. By combining Quobly’s silicon-based quantum processors with SEALSQ’s post-quantum security technologies, this partnership will drive the development of secure quantum computing systems. It supports the development of reliable quantum systems for industrial and critical applications.”
Philippe Delmas, Chairman of the Board at Quobly, said:
“Quobly uniquely combines breakthrough scientific capabilities with rigorous industrial execution. The company is positioning itself at the intersection of three strategic fields—quantum computing, semiconductor manufacturing, and high-performance computing infrastructure—that will shape the next generation of computing technology.”
