Quobly Partners with ST to Advance Quantum Processor Manufacturing for Scalable Quantum Computing

The partnership will utilize ST’s 28nm FD-SOI semiconductor manufacturing process to enable cost-effective, large-scale quantum computing solutions.

Quobly, an innovative quantum computing startup, has announced a significant partnership with STMicroelectronics, a leading global semiconductor company, to manufacture quantum processor units (QPUs) at scale. This collaboration aims to utilize STMicroelectronics‘ breakthrough FD-SOI semiconductor process technologies to render large-scale quantum computing viable and economical, thereby establishing both firms at the leading edge of next-generation computing technologies.

Quobly intends to surpass the 1-million-qubit threshold by 2031, focusing on applications in medicines, finance, materials science, and complex systems modeling, such as climate and fluid dynamics simulations. The two businesses intend to attain a breakthrough in quantum computing by leveraging their shared experience in FD-SOI, reducing R&D expenses, and meeting the market’s need for scalable, cost-effective quantum computing processors.

During the initial phase of the partnership, Quobly and ST will modify ST’s 28nm FD-SOI process to align with Quobly’s specifications, aiming for a 100 Qubit Quantum Machine with demonstrable scalability exceeding 100k physical qubits. ST will utilize its integrated device manufacturer model to provide Quobly with its capability to incorporate co-design, prototyping, industrialization, and large-scale volume production in 300mm fabs. It employs FD-SOI, a technology developed and commercially utilized for years in automotive, industrial, and consumer applications.

Quobly is a leader in creating a fault-tolerant quantum computer utilizing semiconductor qubits. Quobly employs an innovative approach to tackle techno-scientific obstacles and industrial manufacturing, facilitating the bulk manufacture of the millions of qubits necessary for functional, large-scale quantum computers. The business, located in Grenoble, is the culmination of 15 years of collaborative research including esteemed research and technology organizations, CEA Leti and CNRS. Established in 2022, Quobly has assembled a team of specialists from the semiconductor sector and recognized researchers in quantum technologies. In 2023, Quobly garnered attention by securing a seed round of 19 million euros, setting a new benchmark for initial funding of a European firm in the quantum domain.
