Quobly banked €115M in a Series A round co-led by Bpifrance, Sealsq, and STMicroelectronics. The funding includes participation from the European Innovation Council (EIC), Blast, Innovacom, and Aliad, the venture capital arm of Air Liquide.
The Grenoble-based startup develops quantum processors using silicon-on-insulator technology. By utilizing silicon, the same material found in standard semiconductors, Quobly aims to manufacture quantum chips within existing industrial foundry infrastructure. This approach is intended to overcome the scalability challenges of trapping qubits by using the high-yield processes of the traditional chip industry.
The new capital will transition Quobly’s production from pilot lines at research institute CEA-Leti to industrial-scale manufacturing through a strategic partnership with STMicroelectronics. The company, which is largely pre-revenue but secured €10M in contracts via France’s Proqcima programme, plans to make its first quantum computer available through the cloud by the end of 2026.
As European deeptech matures, the emergence of megarounds for silicon-based quantum hardware suggests a shift toward industrialised sovereign supply chains for next-generation computing.
