New cryogenic platform supports Quobly’s quantum roadmap

Absolut System has developed the QCube 100-Class 3, a cryogenic platform delivering 100 mW of cooling power at 500 mK and designed to support the scaling of Quobly’s spin-qubit quantum computers. The platform marks a transition from research and development to a cryogenic solution adapted for a quantum computing product, funded through the French program Cryonext. “As the capabilities of our quantum computers increase, so do their cooling and integration requirements,” says Nicolas Daval, Chief Engineering Officer at Quobly; with this collaboration, the companies aim to prevent cryogenics from becoming a limiting factor in quantum computer scaling. QCube 100-Class 3 Platform Supports Quobly’s Spin-Qubit Scaling The partnership, formalized through an Industrial Partnership Declaration, aims to provide cryogenic infrastructure that scales alongside Quobly’s increasing qubit counts and integrated control electronics. Quobly defined the performance requirements driven by its processor designs and product roadmap, while Absolut System used its expertise in thermal engineering to tailor the QCube 100-Class 3 accordingly. This close collaboration is structured around a four-phase roadmap intended to progressively support the scaling of Quobly’s quantum computers; the current milestone focuses on the development and qualification of the initial platform, the company says. The French program Cryonext funded the development of the QCube 100-Class 3, demonstrating a strategic investment in cryogenic infrastructure as a critical component of quantum computing industrialization. This partnership signals a move beyond purely experimental quantum systems and toward commercially viable, scalable quantum processors. Four-Phase Roadmap Aligns Cryogenic Development with Alloy Processors Phase two will concentrate on industrializing and replicating this first generation, with a stated goal of doubling its thermal dissipation capacity to meet increasing demands. Looking ahead, phase three will shift toward developing a new generation of cryogenic platforms specifically tailored to the requirements of Quobly’s future quantum computers, anticipating advancements in processor design. The final phase outlines volume production of platforms capable of supporting a significant leap in qubit count, aiming for systems that can accommodate 100,000 physical qubits and beyond. This ambitious timeline aligns directly with Quobly’s Alloy quantum computer roadmap, which projects a first generation of systems reaching up to 100,000 physical qubits between 2027 and 2029. According to the partnership declaration, this progression is not merely about increasing qubit numbers, but also about enabling fault-tolerant quantum computing through continued scaling, ultimately targeting systems capable of reaching one million qubits. This phased approach allows for continuous refinement and adaptation of cryogenic solutions as Quobly’s processor technology evolves, ensuring a cohesive and scalable quantum computing architecture.
