Quobly, a Grenoble-based quantum computing startup, has announced a strategic collaboration with STMicroelectronics to develop and scale quantum processor units (QPUs). The partnership leverages ST’s 28nm FD-SOI semiconductor manufacturing process, known for its cost efficiency and scalability. This collaboration is a significant step toward cost-competitive, large-scale quantum computing solutions. The company also announce work with CEA-Leti to develop FD-SOI based processing for devices that run at cryogenic temperatures including both the spin qubits and control electronics.

The first phase of the collaboration will focus on adapting ST’s FD-SOI process to meet Quobly’s quantum processor requirements. The goal is to develop a 100-qubit machine with proof of scalability beyond 100,000 physical qubits, targeting a wide range of applications such as pharmaceuticals, materials science, and climate modeling. By integrating ST’s industrial capabilities with Quobly’s quantum expertise, the collaboration aims to accelerate quantum computing’s industrialization timeline.

Quobly plans to achieve a fault-tolerant, 1-million-qubit system by 2031, which could transform computational challenges in fields like energy and AI. This effort aligns with Quobly’s broader mission to address both technical and industrial hurdles for practical quantum computing, leveraging research from CEA Leti and CNRS.

STMicroelectronics, known for its sustainable and innovative approaches, will utilize its experience in semiconductor manufacturing and co-design to support this initiative, ensuring the scalability and viability of quantum computing technologies.
