The round was announced on June 3, 2026 and is intended to accelerate industrialization of Quobly’s silicon-based quantum computing platform and support launch of its first commercial cloud-accessible system by the end of 2026. Quobly is a French quantum computing company focused on silicon-based quantum computers. The company’s backers and existing shareholders mentioned in the coverage include the CEA, CNRS, Quantonation, and Supernova Invest. No valuation, revenue, or EBITDA was disclosed.
May 2025Series AQuantonation (lead)$7MQuobly, a French quantum microelectronics startup founded in 2022, develops silicon-based quantum processors using technology from CEA and CNRS research. The company secured €21 million ($23.7 million USD) on May 22, 2025, to industrialize its Q100T project, a 100-physical-qubit processor manufactured on 300 mm FD-SOI wafers compatible with standard semiconductor processes. The funding comprises a €15 million grant from Bpifrance under the France 2030 program and €6 million in co-investment from Quobly’s own equity, noted as $6.8 million USD in some reports. Quobly has partnered with STMicroelectronics for manufacturing support and appointed former Airbus VP Philippe Delmas as board chair, targeting production readiness by 2027.

The technology builds on 15 years of research from CEA and CNRS, aiming to produce quantum bits compatible with conventional chip fabs for industrial-scale quantum computing. On July 12, 2023, Quobly closed its first €19M seed funding round, described as the largest seed for a European quantum company in private capital, led by Quantonation, Bpifrance via the Deep Tech 2030 fund (part of France 2030), Supernova Invest, and Innovacom, with participation from Crédit Agricole Alpes Development, CEA Investissement, Caisse d’Epargne Rhone Alpes, and BNP Paribas. The funds are allocated to double R&D efforts, establish remote access interfaces for software development, form technological partnerships, accelerate qubit quantity and quality advancements, and recruit top experts in silicon and quantum engineering, targeting 50 employees by end-2024. Quobly positions itself as a leader in silicon-based quantum computing by integrating quantum bits into standard semiconductor workflows, supported by sector experts and aligning with France's national quantum strategy. In subsequent developments, it partnered with STMicroelectronics for manufacturing and appointed former Airbus VP Philippe Delmas as board chair. A separate €21M package announced in May 2025, including a €15M grant from Bpifrance (France 2030) and €6M equity co-investment, targets industrialization of the Q100T 100-qubit processor for production-readiness by 2027, distinct from the 2023 seed round.
