The French government has decided to support the Research & Development program QRYOLink (Quantum cRYOgenic Link) thanks to I-DEMO grants and repayable advances, through Bpifrance. The total QRYOLink budget is close to 8 million euros for a duration of 54 months. This project aims at designing and developing the next generation of microwave cabling system for cryogenic quantum machines, to enable their scale-up from a few qubits today to one million physical qubits at the end of the project.
Quantum computing promises to be a technologic revolution. Quantum computers will be able to solve complex problems which are out of the scope of today’s most powerful super-computers. However, transforming this promising technology into a reality will require industrial breakthroughs in other domains such as cryogenics, control electronics or microwave cabling… These “enabling technologies” are at the heart of the QRYOLink project, making it part of the French national quantum initiative and belong to the large-scale quantum roadmap.
Both industrial sovereignty and technological superiority are driving factors to push the research and development activities of the consortium. The project’s goals are to increase significantly the number of microwave lines within a cryostat, to increase the signal flow within each line, and reduce heat loads, by developing industrial and competitive technologies. To reach these goals, complementary strategies will be implemented: experimental approaches, experiment-based simulation of quantum architectures, and a fundamental approach to optimize the overall energy and resource consumption of quantum computing. The developed technology will be qubit-type independent to answer the needs of the whole cryogenic quantum ecosystem.
QRYOLink gathers all the French quantum hardware value chain to reach its ambitious goals. All the partners and their main contributions to the project are listed below.
About Alice & Bob
Alice & Bob is a start-up whose goal is to realize the first universal, fault-tolerant quantum computer thanks to its core technology: dissipative cat qubits on superconducting devices. Within the project, Alice & Bob will bring its expertise on engineering cryogenic microwave cablings for quantum devices, and will play the role of a specifier.

About C12
C12 is leading the next materials leap in quantum computing. C12 is a spin-off from ENS launched in January 2020 by twin brothers Matthieu and Pierre Desjardins to supercharge the development of the lab’s promising new quantum technology. Unlike other quantum computers, C12 uses carbon nanotubes as the fundamental building block of their processor. By combining the power of an ultra-pure material with an easy-to-manufacture semiconductor device, they are building a scalable platform for quantum computing.

About CRYOCONCEPT
Cryoconcept designs and manufactures ultra-low temperature refrigerators for fundamental research and quantum computing. Making quantum computers achieve their full potential for the benefit of society will require technological breakthroughs so that they can have high levels of power at low temperature. A subsidiary of Air Liquide, world leader in gases and services for industry and health, Cryoconcept relies on several of the Group’s technology bricks in order to achieve this breakthrough. The need of cooling power for quantum computer is largely due to the heat loads brought by the cabling needed to control the quantum bits, hence the need to find innovative solutions for cabling with QRYOLink project.
