French quantum computing startup Quobly has secured €21 million ($23.7m) in funding to support the production of its silicon quantum chip with 100 physical qubits, dubbed the Q100T project.

The funding package includes a €15m ($17m) grant from Bpifrance as part of the France 2030 program and €6m ($6.8m) in Quobly’s shareholder equity.

Founded in 2022, the company’s technology is based on research from CEA (the French Alternative Energies and Atomic Energy Commission) and CNRS (the National Centre for Scientific Research).

The processor that forms the basis of Quobly’s Q100T project will be manufactured on 300mm FD-SOI wafers, aligning with standard semiconductor industry tools and processes, with the startup having already demonstrated a qubit on a 300mm plate, making it compatible with standard manufacturing tools.

In late 2024, Quobly announced it was partnering with STMicroelectronics to help manufacture its chips, with production-readiness targeted for 2027. The startup also recently announced the appointment of former Airbus VP Philippe Delmas as chairman of the board.

“With this funding, we are entering the home stretch towards the industrialization of our technology,” Maud Vinet, CEO and co-founder of Quobly. “Our initial goal to make quantum technology accessible, controllable, and scalable is now becoming a reality.”
