Dallas/Paris – June 3, 2026 – Quantonation portfolio company Quobly has announced a €115 million Series A financing to accelerate the industrialisation of its silicon-based quantum computing platform and bring its first commercial product to market by the end of 2026.

The financing is one of the largest quantum computing rounds announced globally and underscores a broader transition across the industry. While the past decade focused on proving quantum computers could work, the next will be defined by the ability to manufacture, scale and deploy them in real-world environments.

“The first chapter of quantum computing was about physics. The next chapter is about manufacturing,” said Quantonation Managing Partner Olivier Tonneau. “Quobly recognised that early, and built its strategy around the idea that quantum computers should be produced with the same industrial discipline that transformed the semiconductor industry.”

This Series A marks a significant step in Quobly’s roadmap toward industrial-scale quantum computing. Quantonation invested in the startup’s €19 million seed round in 2023, during which the company demonstrated the feasibility of developing silicon qubits within semiconductor manufacturing processes and established a system-level architecture integrating hardware, control electronics and software.

The company plans to deploy Alloy Pioneer, the first system in its Alloy product line, through the cloud by the end of 2026. Designed for early adopters in high-performance computing and research environments, the platform will provide access to silicon-based quantum processors developed using established semiconductor manufacturing processes.

Future deployments into high-performance computing infrastructures are expected to follow in 2027.

The financing will support continued research and development, industrialisation efforts and international commercial expansion. It will also enable Quobly to accelerate the scaling of its silicon quantum processors and deploy its first commercial systems into cloud and HPC environments.

Since Quantonation’s initial investment, one of the key attractions of Quobly has been its conviction that quantum computing can leverage the same industrial foundations that transformed the semiconductor industry.

Quobly’s approach is based on FD-SOI technology manufactured on 300 mm wafers, allowing the company to build quantum processors using mature semiconductor fabrication processes. This strategy aims to address some of the industry’s most significant challenges around scalability, yield and reproducibility.

The company has established strategic partnerships with industrial leaders including STMicroelectronics, Air Liquide, Soitec and Orano, bringing expertise in semiconductor manufacturing, materials engineering, cryogenics and industrial process control.

By prioritising manufacturability from the outset, Quobly is pursuing a path that aligns quantum computing development with the realities of industrial deployment.

For Quantonation, the round highlights growing confidence in Europe’s ability to build globally competitive quantum computing companies.

“One of the central questions facing the industry is how quantum computing moves from laboratory demonstrations to industrial products,” Tonneau added. “Quobly’s strategy has always been to build on the foundations of the semiconductor industry rather than reinvent them. This financing is an important validation of that vision and provides the resources needed to accelerate the company’s path toward commercial deployment.”

As demand for next-generation computing infrastructure continues to grow, Quobly’s progress reflects a broader evolution within the quantum sector: from proving that quantum computers can work to proving they can be built, deployed and scaled.
