Quantum computing has long promised to revolutionise industries ranging from drug discovery and materials science to cybersecurity and financial modelling. Yet despite billions invested globally, one challenge continues to hold the sector back: building quantum computers that can be manufactured reliably and at scale.
French startup Quobly believes the answer lies in an unlikely place, the same semiconductor manufacturing processes that power today’s computer chips.
The Grenoble-based company has raised €115 million in Series A funding to accelerate the industrialisation of its silicon-based quantum computers and bring its first commercial product to market by the end of 2026.
The round was led by Bpifrance, SEALSQ, and STMicroelectronics, with participation from the European Innovation Council (EIC), Blast, Air Liquide Venture Capital (ALIAD), and existing investor Innovacom. Existing shareholders also include CEA, CNRS, Quantonation, and Supernova Invest.
The funding marks one of Europe’s largest quantum computing rounds this year.
Founded in 2022 by Maud Vinet, Tristan Meunier and François Perruchot in Grenoble, Quobly emerged from years of semiconductor and quantum research.
Unlike many quantum startups pursuing exotic hardware architectures, Quobly is focused on silicon qubits manufactured using FD-SOI technology on 300mm wafers, the same industrial processes already used across the semiconductor industry.
The company’s thesis is that quantum computing will only become commercially viable if it can leverage the manufacturing scale, reproducibility, and quality controls already established in the semiconductor ecosystem.
Quobly demonstrated that silicon qubits could be developed within existing semiconductor manufacturing processes while integrating hardware, control electronics, and software into a unified system architecture.
The company is now moving from technology validation to commercial deployment. Its first product, Alloy Pioneer, will be made available through the cloud in 2026 before being deployed into high-performance computing (HPC) environments in 2027.
“Quobly combines breakthrough scientific innovation with industrial execution, positioning itself at the intersection of quantum computing, semiconductor manufacturing, and high-performance computing infrastructure,” adds Philippe Delmas, Chairman of the Board, Quobly.
One of the biggest barriers to quantum computing adoption is scalability. Many quantum systems remain difficult to manufacture, requiring specialised materials, complex fabrication techniques, and custom infrastructure.
Quobly is taking a different approach by building quantum processors designed to fit into existing data centre and HPC environments. Its systems are being developed with compatible power, utility, and deployment requirements, allowing organisations to integrate quantum capabilities without redesigning their infrastructure.
The company has also built Alloy Forge, a development environment that enables customers to create and test quantum applications under real-world hardware constraints before large-scale deployment.
Quobly enters a highly competitive market where startups are pursuing different paths to practical quantum computing.
Among the most prominent rivals is Pasqal, the French quantum computing company that raised €100 million to commercialise its neutral-atom quantum technology and expand globally. Pasqal has become one of Europe’s best-funded quantum startups and is focused on delivering quantum advantage for industrial applications.
Another major competitor is Finland’s IQM, which secured €128 million in funding to accelerate the development of superconducting quantum computers and strengthen its position across Europe and Asia.
Meanwhile, US-based PsiQuantum closed $1 billion in September 2025, bringing its total funding to over $2.1 billion and its valuation to $7 billion to build utility-scale quantum computers using photonic technology.
Quobly is differentiating itself through semiconductor compatibility. The company believes leveraging existing chip manufacturing infrastructure offers a faster route to large-scale quantum systems.
As governments and enterprises increasingly view quantum computing as a strategic technology, investors are looking for platforms that can move beyond research demonstrations and into industrial deployment.
Quobly’s partnerships with STMicroelectronics, Air Liquide, Soitec, and Orano strengthen that positioning by providing access to expertise in semiconductor manufacturing, cryogenics, materials engineering, and industrial process control.
The broader opportunity is significant. Quantum computing is expected to become a foundational technology for next-generation computing, but only if the industry can solve the manufacturing challenges that have limited scalability.
“Quantum computing will only reach the scale HPC customers need if it can be industrialised with semiconductor-grade manufacturing and a strong ecosystem. Our long-standing collaboration and expertise in FD-SOI technology will help accelerate Quobly’s commercialisation and global ambitions,” says Laurent Malier, Executive Vice President, Global Technology R&D, STMicroelectronics.
“Quobly’s semiconductor-compatible quantum architecture aligns with our mission to support sovereign technology champions. Its approach creates a pathway for the industrialisation of quantum computing and strengthens Europe’s technological autonomy,” notes Gwenaël Hamon, Senior Investment Director, Bpifrance.
“This investment builds on our partnership with Quobly and combines its silicon-based quantum processors with our post-quantum security technologies to help develop trusted quantum systems for industrial and critical applications,” notes Carlos Moreira, CEO, SEALSQ.
The latest funding will be used to improve the performance and scalability of Quobly’s quantum systems, accelerate processor industrialisation, and deploy the first Alloy systems into customer cloud and HPC environments.
