Scalable Platform for Quantum Technology – SPROUT

Delft Circuits and kiutra team up for SPROUT

Providing a scalable platform for quantum technologies

Quantum technologies and their commercial exploitation are one of the most important development areas for the next decades. While significant progress has been made in the research of quantum effects, their adoption and scaling up towards commercial applications is hindered by the complexity of current cryogenic cooling solutions. To solve this problem Delft Circuits and kiutra have teamed up for the SPROUT project to build an easy-to-use multi-channel cooling platform that facilitates the development and operation of quantum hardware.

The goal of this project is to provide a fully integrated, turnkey cooling platform as the go-to solution for quick and reliable testing of components or building multi-node quantum networks – it therefore combines a reliable, low maintenance cooling technology with integrated electronics for quantum experiments.

What we are doing

System integration and development of core components

We will develop a demonstrator for a sub-Kelvin platform that is based on cryogen-free magnetic cooling but at the same time offers multi-channel electrical access – this will enable various applications in the field of quantum electronics and quantum optics.

The main technical challenge for us is the delicate heat management of all integrated components, including the mechanical pre-cooling achieved with a closed-cycle cryocooler, the ADR cooling media, superconducting ADR magnets, heat switches, wiring, optical fibers, and low-temperature amplifiers. Further technical complexity arises from the vibration isolation needed to reduce the mechanical motion introduced by the cryocooler.
