Quobly Raises €115 Million for Silicon Quantum Computing Industrialization

Quobly, a French company at the forefront of developing silicon-based quantum computers, has announced the completion of a significant Series A funding round, raising €115 million. This capital is earmarked for a decisive acceleration in the industrialization of its technology and the launch of its first commercial products on the market. The round was led by key players such as Bpifrance, SEALSQ, and STMicroelectronics, with participation from other strategic investors, including the European Innovation Council (EIC), Blast, Air Liquide Venture Capital (ALIAD), and existing investor Innovacom.

This funding marks a crucial transition for Quobly, shifting its focus from technological validation to large-scale industrial deployment. As Maud Vinet, CEO and co-founder of the company, emphasized, the objective is to make quantum computing not only deployable and scalable but also concretely usable within real industrial environments, integrating with existing computing infrastructures. This perspective is particularly relevant for CTOs and infrastructure architects evaluating the integration of new advanced computing capabilities.

The Technological Core: Silicon and Scalability for Quantum

Quobly's approach is based on FD-SOI (Fully Depleted Silicon-On-Insulator) technology, manufactured on 300 mm wafers. This strategic choice allows the company to leverage established and mature semiconductor manufacturing processes, a critical factor in addressing the intrinsic challenges related to scalability, production yield, and reproducibility of quantum components. The ability to rely on existing supply chains and fabrication methodologies is a significant competitive advantage in the emerging quantum computing landscape.

The company focuses on developing silicon qubits, specifically designed for high-density integration and full compatibility with industrial fabrication standards. This compatibility is fundamental for mass production and cost reduction, essential elements for large-scale adoption. The first system in Quobly's Alloy product line, named Alloy Pioneer, is expected to be released via the cloud in 2026, through Alloy Forge, the company's quantum application development platform.

Deployment Strategies and Integration with Existing Infrastructure

Quobly's deployment strategy involves initial availability via the cloud, followed by direct integration into High-Performance Computing (HPC) environments. This hybrid approach is designed to facilitate the adoption and access to quantum technology, allowing users to experience Alloy Pioneer's capabilities before a deeper deployment. Quobly's quantum computers are engineered to integrate seamlessly with existing HPC and data center infrastructures, a crucial aspect for companies looking to leverage quantum computing without overhauling their current technology stacks.

For organizations evaluating self-hosted alternatives or on-premise deployment for AI/LLM workloads, the ability to integrate new computing technologies into existing environments is a key factor. This approach reduces the Total Cost of Ownership (TCO) and allows for maintaining control over data sovereignty, fundamental aspects for many sectors. Quobly is collaborating with partners across the semiconductor ecosystem to optimize the development and manufacturing of its technology, covering areas such as process control, materials engineering, cryogenics, and yield optimization.

Future Prospects and Impact on the Quantum Computing Market

The funds raised will be used to further improve the performance and scalability of Quobly's quantum computing platform, to advance the industrialization of its silicon quantum processors, and to support the deployment of the first Alloy systems in both cloud and HPC environments. These efforts will be supported by the continued development of the company's hardware, control electronics, and software stack through a system-level co-design approach.

Quobly's commitment to making quantum computing an industrial and integrable reality reflects a broader trend in the industry, which sees increasing attention towards practical and deployable solutions. The ability to leverage existing infrastructures and offer a clear path towards scalability and reproducibility positions Quobly as a significant player in the quantum computing landscape, with potential implications for accelerating complex workloads across various industrial sectors.
