Quobly, a French quantum computing company, has announced the closing of a €115 million Series A financing round to accelerate the industrialization of its silicon-based quantum computers and bring its first commercial product to market by the end of 2026. The round is led by Bpifrance, SEALSQ, and STMicroelectronics, with participation from the European Innovation Council Fund, Blast, ALIAD, and existing investor Innovacom. Existing shareholders also include the CEA, CNRS, Quantonation, and Supernova Invest. Bpifrance is participating through its Deep Tech 2030 fund, managed on behalf of the French government as part of the France 2030 initiative.
Founded in 2022 and headquartered in Grenoble, France, Quobly’s approach is built on FD-SOI technology on 300mm wafers, leveraging established semiconductor manufacturing processes to address key challenges in quantum computing scalability, yield, and reproducibility. The company develops silicon qubits designed for dense integration and compatibility with industrial fabrication standards — a manufacturing-first philosophy that sets it apart from quantum computing approaches that rely on more exotic or difficult-to-scale hardware. Strategic partnerships with STMicroelectronics, Air Liquide, Soitec, and Orano accelerate the transfer of Quobly’s quantum technologies into advanced manufacturing environments, covering process control, materials engineering, cryogenics, and yield optimization.
The financing will support the deployment of Alloy Pioneer, the first product in Quobly’s Alloy line, which is designed for early adopters in high-performance computing and research environments. Alloy Pioneer will be accessible through the cloud in 2026 before deployment within HPC infrastructures in 2027, and is accessible through Alloy Forge, Quobly’s quantum application development environment. The fresh capital will also fund continued R&D, industrialization of silicon quantum processors, and international commercial expansion. The Series A follows a €19 million seed phase from 2023 to 2025 during which Quobly demonstrated the feasibility of developing silicon qubits within semiconductor manufacturing processes.
KEY QUOTES:
“This financing marks a transition from technology validation to industrial execution. 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.”
Maud Vinet, CEO and Co-Founder, Quobly
“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. ST’s investment in Quobly further demonstrates our commitment to support its global ambitions.”
Laurent Malier, Executive Vice President, Global Technology R&D, STMicroelectronics
