Grenoble-based firm Quobly, which develops silicon-based quantum computing systems using semiconductor manufacturing processes, has secured a €115 million Series A led by Bpifrance, STMicroelectronics and SEALSQ, with participation from the European Innovation Council, ALIAD, Blast Club and INNOVACOM, alongside existing investors including CEA, CNRS, Quantonation and Supernova Invest.
- Founded in 2022 by Maud Vinet and Philippe Delmas, Quobly develops industrial quantum computing systems based on silicon qubits manufactured on 300 mm wafers using FD-SOI semiconductor technology.
- The company’s approach focuses on scalability, reproducibility and compatibility with data centre infrastructure, with the long-term goal of reaching million-qubit architectures.
- Quobly builds a full-stack system comprising quantum hardware, cryogenic and control electronics, and software for application development and execution.
- It reports having fabricated more than 2.4 million qubits in collaboration with STMicroelectronics, holds around 65 patent filings, and employs over 90 specialists across France, Singapore and Canada.
- Its strategy relies on leveraging existing semiconductor supply chains and industrial partners including STMicroelectronics, Air Liquide, Soitec and Orano to reduce costs and enable scalable production compared with lab-based quantum computing approaches.
Details of the deal
- The new funding will support industrialisation, performance improvements and full-stack system development, while advancing the company’s first commercial system, Alloy Pioneer, which is planned for cloud access in 2026 and subsequent deployment in high-performance computing environments.
“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. It supports the development of trusted quantum systems for industrial and critical applications," claims Carlos Moreira, CEO of SEALSQ.
