French quantum startup Quobly raises €115 million Series A

A French quantum computing startup has secured a major investment to advance its plan to build commercial systems using existing semiconductor factories. Quobly, based in Grenoble, announced it has closed a 115 million euro Series A financing round led by Bpifrance, SEALSQ, and chipmaker STMicroelectronics.

The funding marks a strategic shift for the company from research and development toward industrial-scale production. CEO and co-founder Maud Vinet stated that the financing signifies a transition from technology validation to industrial execution, with the objective of making quantum computing deployable, scalable, and usable within real industrial environments.

Quobly’s approach centers on building quantum processors, or qubits, using silicon spin-qubit technology manufactured with standard semiconductor techniques. The company argues this method leverages the established scale, cost efficiency, and reliability of the global chip industry, potentially allowing it to produce systems far more affordably than rivals using exotic materials. Vinet has said this could lead to quantum computers that are a hundred times cheaper than competing technologies.
