Quobly and Absolut System Partner on Cryogenic Infrastructure for Spin-Qubit Quantum Computers

Insider BriefPRESS RELEASE — Quobly and Absolut System today announce the signing of an Industrial Partnership Declaration to support the development and scaling of Quobly’s spin-qubit quantum computers. The signing comes as the two companies reach a first major milestone in the QCube® 100-Class 3 program, a high-cooling-power cryogenic platform developed by Absolut System to meet the requirements of Quobly’s quantum processors. This first project lays the foundation for a cooperation designed to evolve alongside the different generations of Alloy, Quobly’s quantum computer product family. As the number of qubits increases and control electronics become increasingly integrated into the quantum system, cooling and integration requirements evolve accordingly. Cryogenics is therefore becoming a key element of the architecture and industrialization of future quantum computers. QCube® 100-Class 3 is designed to provide 100 mW of cooling power at 500 mK and integrates the thermal, mechanical, electrical and RF interfaces required to integrate and operate Quobly’s quantum computers. Developed as part of the French program Cryonext, it represents the transition from R&D to a first cryogenic solution adapted to the requirements of a quantum computing product. The development of the platform relies on close collaboration between the two companies’ teams: Quobly provides the requirements driven by its processors and product roadmap, while Absolut System contributes its expertise in cryogenic systems and thermal engineering to develop a platform tailored to these needs. The cooperation is structured around a four-phase roadmap, progressively supporting the scaling of Quobly’s quantum computers: This roadmap is aligned with Quobly’s Alloy quantum computer roadmap, with a first generation of systems targeting up to 100,000 physical qubits between 2027 and 2029, followed by further scaling steps from 2030 onwards, towards systems ultimately capable of reaching one million qubits and supporting fault-tolerant quantum computing. The shared objective is to progressively increase cryogenic power, integration, reliability and industrial readiness so that cryogenic infrastructure can keep pace with the scaling of quantum computers. Nicolas Daval, Chief Engineering Officer at Quobly: “As the capabilities of our quantum computers increase, so do their cooling and integration requirements. Today’s cryogenic platforms need to evolve to meet these new requirements.

With Absolut System, we are developing tailored solutions designed around the needs of our Alloy roadmap, with the objective of supporting the progressive scaling of our quantum computers without making cryogenics a limiting factor.” Julien Tanchon, CEO of Absolut System: “QCube® 100-Class 3 is a first concrete step in a cooperation that we intend to develop over the long term. Our objective is to evolve cryogenic capabilities alongside each generation of Quobly’s quantum computers, with greater cooling power and integration, while also designing for reliability and industrialization. We believe cryogenics must become an infrastructure that enables the scaling of quantum computing.” The cooperation highlights the complementary expertise brought together within the Grenoble ecosystem, at the intersection of quantum technologies, semiconductors and cryogenics. Based in the Grenoble region, Quobly and Absolut System each contribute, in their respective fields, to the development of technologies needed for the next generations of quantum computers.TopicsShare Get the latest research, company news, and market intelligence every week. MENTIONED IN THE ARTICLEQuobly, formerly Siquance, was founded in 2022 to develop and commercialize a universal large-scale quantum computer using proven semiconductor-industry processes.
