• This partnership combines Quobly’s quantum expertise with ST’s manufacturing strengths, starting with adapting ST’s 28nm FD-SOI process for a 100-qubit machine scalable to over 100k qubits.
• Industry experts see this collaboration as pivotal for advancing economically viable quantum processors, addressing SWaP-C challenges, and enabling long-term scalability through CMOS wafer-scale manufacturing.

PRESS RELEASE — Quobly, a cutting-edge quantum computing startup, today announced a transformative collaboration with STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, to produce quantum processor units (QPUs) at scale. By leveraging STMicroelectronics’ advanced FD-SOI semiconductor process technologies, this collaboration is set to make large-scale quantum computing feasible and cost-effective, positioning both companies at the forefront of next-generation computing technologies.

Quobly aims to break the 1-million-qubit barrier by 2031, targeting applications ranging from pharmaceuticals, finance, materials science and complex systems modeling, including climate and fluid dynamics simulations. Together, the two companies aim to achieve a breakthrough in quantum computing by utilizing their common expertise in FD-SOI, driving down R&D costs, and addressing the market’s demand for scalable, affordable quantum computing processors.

In the first phase of the collaboration, Quobly and ST will adapt ST’s 28nm FD-SOI process to match Quobly’s requirements, targeting a 100 Qubit Quantum Machine with proof of scalability beyond 100k physical qubits. ST will leverage its integrated device manufacturer model to bring Quobly its ability to bridge co-design, prototyping, industrialization and volume production at scale in 300mm fabs using FD-SOI, a technology it has developed and exploited commercially for years across automotive, industrial and consumer applications.

Maud Vinet, CEO of Quobly, expressed her enthusiasm: “This collaboration is unparalleled in the quantum computing landscape. Working closely with STMicroelectronics will fast-track the industrialization of our quantum processor technology by several years. We are thrilled to leverage ST’s semiconductor manufacturing expertise, which will speed up the development of a fully fault-tolerant quantum computer. We aim at breaking the 1-million-Qubit barrier by 2031, with applications ranging from pharmaceuticals, finance, materials science and complex systems modeling, including climate and fluid dynamics simulations.”

Remi El-Ouazzane, President, Microcontrollers, Digital ICs and RF products Group at STMicroelectronics, said: “Quantum computing will transform the world, starting with AI, chemistry, security and supply chain applications. This collaboration is building on ST’s IDM strengths, centered around our Crolles facility, integrating together our process R&D expertise, our circuit design know-how and volume manufacturing. We truly believe that pairing Quobly’s quantum expertise with ST’s FD-SOI knowledge and manufacturing will allow to accelerate economically viable, large-scale quantum computing solutions.”

“In the future, to be successful, quantum computers still need to work on SWaP-C (size, weight, power, and cost)” explains Eric Mounier, PhD Chief Analyst, Photonics & Sensing at Yole Group. “This is also where semiconductor qubits have a big advantage in scalability by leveraging CMOS wafer-scale manufacturing. Although quantum technologies are long-term, the investment time is today. To that respect, today’s collaboration agreement between STMicroelectronics and Quobly could mark a major step for cost-efficient and more scalable quantum computing processors” (1)
