Avolta has acted as the equity financial advisor to Quobly, a leading French quantum computing company developing silicon-based quantum computers leveraging semiconductor-grade manufacturing processes, on its €115m Series A financing round.
The round was led by Bpifrance, SEALSQ and STMicroelectronics, with participation from the European Innovation Council (EIC Fund), Blast, ALIAD (Air Liquide Venture Capital) and existing investor Innovacom. Historical shareholders also include CEA, CNRS, Quantonation and Supernova Invest. This transaction marks a major milestone in Quobly’s transition from technology validation to industrial-scale commercialization of quantum computing systems.
Quobly.
Founded in Grenoble in 2022, Quobly develops silicon-based quantum computers designed to bring semiconductor-grade industrialization to the quantum computing industry. The company’s differentiated approach relies on FD-SOI technology manufactured on 300 mm wafers, leveraging established semiconductor processes to address the scalability, reproducibility and yield challenges that have historically limited quantum computing deployment.
Quobly develops silicon qubits optimized for dense integration and compatibility with industrial fabrication standards. Through strategic partnerships with leading industrial players including STMicroelectronics, Air Liquide, Soitec and Orano, the company combines cutting-edge quantum technologies with advanced semiconductor manufacturing capabilities. With more than 100 employees across France, Singapore and Canada, Quobly is building a fully integrated quantum computing platform spanning hardware, control electronics and software.
The company plans to launch Alloy Pioneer, the first system in its Alloy product line, through cloud deployment by the end of 2026, targeting early adopters in high-performance computing (HPC) and research environments.
Transaction Rationale.
This financing will support the continued development and industrialization of Quobly’s quantum computing platform, accelerate the scaling of its silicon quantum processors and fund the commercial deployment of its first Alloy systems into cloud and HPC environments. The transaction enables Quobly to move from technology validation toward industrial execution and commercial deployment at scale.
The support of leading sovereign, industrial and deeptech investors reinforces Quobly’s unique positioning at the intersection of quantum computing, semiconductor manufacturing and high-performance computing infrastructure. The participation of STMicroelectronics and ALIAD further strengthens the company’s industrial ecosystem, while Bpifrance’s continued backing underscores the strategic importance of developing a European quantum computing champion.
