Low temperatures close to absolute zero (0 degrees Kelvin) are required for materials science, detectors for the aerospace and military sector, quantum computing, and quantum electronics. These temperatures are commonly achieved by using cryogenic liquefied gases (cryogens), such as liquid helium (He). However, there are a numbers of problems related to the use of these cryogens which include the oligopoly of He-3, high costs of cooling machines (€ 300-600k), and safety problems. To solve these pains, kiutra has developed a cryogen-free, continuous, and fully automatic refrigeration system based on a cryogenic magnetic cooling process known as (Continuous) Adiabatic Demagnetization Refrigeration - (C)ADR. (C)ADR uses widely available and low-price cooling media, saving € 20-40k/year in comparison with typical refrigeration systems that use He-3. Moreover, the system has a complete modular and customizable design, as it can be extended with multiple units according to the cooling requirements. It also offers a wide and stable temperature range while being easy to operate and hazard-free, thanks to the elimination of cryogens. kiutra, founded in 2018 in Germany, builds easy-access turn-key refrigeration solutions. Their cooling devices combine magnetic refrigeration and closed-cycle pre-cooling to provide cryogenic temperatures without cryogens. kiutra is currently funded by “EXIST Transfer of Research”, and has raised almost € 2M to date.

In the rapidly evolving landscape of quantum technology, Europe faces a critical gap in access to professional testing & characterization services. With a growing number of players entering the quantum ecosystem, the need for a centralized, advanced, & accessible facility to perform cryogenic measurements on sensitive devices is more pronounced than ever. kiutra has a breakthrough solution to this challenge: a state-of-the-art low-temperature characterization service leveraging our cutting-edge cryostat hardware. This places us in pole position to offer rapid, precise testing for an affordable fee, ‘Cryogenics-as-a-Service’, reducing test result times from weeks-months to days and lowering the bar to startups, SMEs, & researchers without capital/expertise to acquire/manage specialized low-temperature hardware. With our solution poised to transform markets, kiutra presents a timely opportunity for EIC support, propelling our innovative European company to global quantum industry leadership.

The objective of the LEMON project is the development and technical demonstration of a process for the scalable, permanent, helium-3-free generation of very low (cryogenic) milli-Kelvin temperatures based on continuous Adiabatic Demagnetization Refrigeration (cADR). It is aimed at providing the technical basis for large-scale refrigeration systems with, in principle, arbitrarily high cooling capacities at cryogenic temperatures, by connecting the same basic cooling unit together many times. The proposed novel approach to large-scale cryogenic cooling promises to meet for the first time the growing and diverse cooling requirements in the field of quantum technologies, especially in the field of quantum computing (QC). It will make the high cooling powers required for QC (in the range of some hundred µW to several ten mW) available for the first time ever, thereby lifting the disruptive and ultimately economic potential of QC. In addition, the dependence on the critical resource helium-3, which is only available to a very limited extent in the EU and so far cannot be substituted, will be resolved; Overall, a decisive contribution can be made to the technological sovereignty, competitiveness and technological leadership of the EU in the field of applied quantum technologies.
