Summary

French quantum startup Quobly secured €115m in Series A funding on June 3, 2026, co-led by Bpifrance, Sealsq, and STMicroelectronics, with additional participation from EIC, Blast, Innovacom, and Aliad. This capital will scale its quantum chip production from lab to industrial levels. Quobly's unique approach utilizes silicon, a standard semiconductor material, to trap qubits, enabling the use of existing semiconductor manufacturing infrastructure. The company aims to produce millions of qubits, having already created quantum chips on a pilot line with CEA-Leti. A partnership with STMicroelectronics will facilitate the transfer to industrial settings. Quobly plans to offer its first quantum computer commercially via the cloud by late 2026 and deploy devices in customer infrastructure by 2027, competing with other silicon qubit developers like Quantum Motion.

Key takeaway

For investors evaluating quantum computing opportunities, Quobly's €115m Series A highlights the growing viability of silicon-based qubit approaches. Your due diligence should prioritize startups utilizing existing semiconductor manufacturing, as this strategy promises faster industrial scaling and lower production costs. Consider the competitive landscape, including firms like Quantum Motion, and assess their partnerships with established chipmakers for market readiness and deployment timelines, especially for cloud-based offerings by late 2026.
