French Startup Quobly Secures €115 Million to Commercialise Affordable Quantum Computers
Grenoble, Wednesday 3 June 2026
French startup Quobly has raised €115 million to commercialise quantum computers. By adapting standard semiconductor manufacturing, the firm aims to produce chips 100 times cheaper than competing technologies.
Scaling Up with Semiconductor Standards
The Series A funding round, announced on 2 June 2026, was led by the French state investment bank Bpifrance, semiconductor giant STMicroelectronics, and cybersecurity firm SEALSQ [1][2]. This capital injection marks a critical transition for the Grenoble-based firm, which was founded in 2022 and previously operated on a 19 million euro seed fund raised between 2023 and 2025 [1]. With a total historical funding of 134 million euros, Quobly aims to move from technological validation to industrial execution [1]. Rather than relying on exotic and highly unstable quantum components, the company leverages modified silicon transistors manufactured on 300-millimetre FD-SOI (Fully Depleted Silicon On Insulator) wafers [1][2]. By exploiting existing semiconductor fabrication standards, Quobly intends to overcome the reliability issues that have historically plagued quantum computing hardware [2].
Securing European Sovereignty and Critical Infrastructure
The geopolitical race for quantum supremacy forms a vital backdrop to Quobly’s funding success. In May 2026, French President Emmanuel Macron pledged 1 billion euros towards quantum computing initiatives, directly following a 2 billion US dollar funding announcement by US President Donald Trump [2]. Against this highly competitive international landscape, Bpifrance’s senior investment director, Gwenaël Hamon, explicitly framed the Quobly investment as a move to guarantee Europe’s strategic autonomy in disruptive technologies [1]. By building quantum processors that conform to established microelectronics standards, Europe is positioning itself to avoid reliance on foreign high-tech systems and materials (HTSM) [1][GPT].
The Commercial Roadmap and Economic Viability
A robust consortium of financial and legal advisors, including BNP Paribas, Société Générale, and Forvis Mazars, facilitated the 115 million euro transaction, which also saw participation from the European Innovation Council (EIC), Air Liquide Venture Capital, and Innovacom [1][2]. The scale of this backing underscores the market’s confidence in Quobly’s aggressive commercial timeline. The firm is scheduled to release its first commercial quantum computer, named Alloy Pioneer, via a cloud-based development environment called Alloy Forge by the end of 2026 [1]. This initial rollout will target early adopters in high-performance computing (HPC) and research sectors [1].
