Quobly Raises €115M for Silicon Quantum Computing

French quantum computing innovator, Quobly, has successfully closed a substantial €115 million Series A funding round. This significant capital infusion is earmarked to propel the industrialization of its silicon-based quantum processors and facilitate the market introduction of its inaugural commercial quantum system by the close of 2026. The funding marks a pivotal shift for the company, moving from technological validation to large-scale manufacturing and deployment.

The investment was spearheaded by prominent entities including Bpifrance, SEALSQ, and STMicroelectronics. Additional backing came from the European Innovation Council (EIC), Blast, Air Liquide Venture Capital (ALIAD), and existing investor Innovacom. The company also benefits from the continued support of its foundational shareholders: CEA, CNRS, Quantonation, and Supernova Invest.

Quobly, a spin-off originating from the esteemed research institutions CEA-Leti and CNRS, is pioneering a unique approach to quantum computing by leveraging established semiconductor manufacturing techniques. Their strategy centers on utilizing Fully Depleted Silicon On Insulator (FD-SOI) technology on 300 mm wafers. This method aims to overcome critical hurdles in quantum computing development, such as scalability, manufacturing yield, and reproducibility, by integrating quantum components within the robust framework of existing semiconductor fabrication processes. This industrial-grade methodology is designed to make quantum computing more accessible and deployable within real-world industrial settings.

The company's vision is to seamlessly integrate quantum computing capabilities into current high-performance computing (HPC) and data center infrastructures. Their forthcoming product line, dubbed 'Alloy', is designed with compatibility in mind, addressing factors like physical footprint, power requirements, and essential utilities. The first system, 'Alloy Pioneer', is slated for cloud-based accessibility in 2026, with on-premise deployments anticipated in 2027. Users will interact with the system through 'Alloy Forge', Quobly's dedicated quantum application development environment, allowing for application testing under realistic hardware constraints.

This funding round follows a successful €19 million seed phase, during which Quobly demonstrated the viability of its silicon qubit technology and established a foundational system architecture encompassing device, control, and software layers. The strategic partnerships forged with industry leaders such as STMicroelectronics, Air Liquide, Soitec, and Orano are crucial for accelerating the transition of Quobly's quantum innovations into advanced manufacturing environments. These collaborations ensure that process control, materials science, cryogenics, and yield optimization are integrated from the outset, reinforcing the company's commitment to an industrial-first development model.

The global quantum computing market is projected for significant expansion, with estimates suggesting it could reach tens of billions of dollars within the next decade. Companies like Quobly, by focusing on manufacturability and integration with existing silicon infrastructure, are positioning themselves to capture a substantial share of this burgeoning market. Their success could significantly accelerate the adoption of quantum solutions across various sectors, including pharmaceuticals, materials science, finance, and artificial intelligence.
