Quobly Secures €115 Million Series A to Bring Silicon-Based Quantum Computers to Market

Quobly, building industrial silicon-based quantum computers, led by Maud Vinet, Tristan Meunier, and the team, has announced the closing of a €115 million Series A financing led by Bpifrance, SEALSQ, and STMicroelectronics, with participation from the European Innovation Council (EIC Fund), Blast, ALIAD (Air Liquide Venture Capital), and existing investor Innovacom, bringing together leading industrial, sovereign, and deeptech investors. Existing shareholders also include the CEA, CNRS, Quantonation, and Supernova Invest.

Supporting Commercialization and Global Expansion.

The financing, provided on behalf of the French government through the France 2030 initiative, will support Quobly’s ongoing research and development, industrialization efforts, and international commercial expansion.

The company aims to bring semiconductor-grade manufacturing processes to quantum computing and plans to launch its first commercial cloud-accessible quantum computer by the end of 2026 as part of its Alloy product line.

Moving Toward Commercial Quantum Computing.

The Series A funding represents an important milestone in Quobly’s transition from technology validation to commercial deployment, supporting the production of its first quantum computing systems.

The company’s first product, Alloy Pioneer, is targeted at early adopters in high-performance computing and research. Cloud access is planned for 2026, followed by deployment within HPC environments in 2027. Designed for compatibility with existing data center infrastructure, the system aims to simplify integration into established computing environments.

Users will be able to access the platform through Alloy Forge, Quobly’s development environment for building and testing quantum applications under real-world hardware conditions.

Advancing Performance, Scale, and Deployment.

The new funding will support efforts to improve the performance and scalability of Quobly’s quantum computing platform, accelerate the industrialization of its silicon-based quantum processors, and deploy the first Alloy systems into customer cloud and high-performance computing environments.

The company will continue expanding its hardware, control electronics, and software capabilities through a system-level co-design strategy that integrates all layers of the quantum computing stack.

The Series A follows a €19 million seed phase between 2023 and 2025, during which Quobly demonstrated the viability of manufacturing silicon qubits using semiconductor industry processes and established the foundational architecture for its quantum computing platform.

Leveraging Semiconductor Manufacturing for Scalable Quantum Computing.

Quobly is pursuing a semiconductor-based approach to quantum computing, using FD-SOI technology on 300 mm wafers to address critical challenges related to scalability, yield, and manufacturing consistency. The company’s silicon qubits are designed to support dense integration while remaining compatible with established semiconductor fabrication processes.

To accelerate industrialization, Quobly collaborates with major industry players including STMicroelectronics, Air Liquide, Soitec, and Orano. These partnerships provide expertise in manufacturing, materials engineering, cryogenics, process control, and yield optimization, helping bridge the gap between quantum research and large-scale production.

The strategy reflects Quobly’s focus on manufacturability and system-level co-development, positioning industrial scalability as a core design principle from the outset.
