The project aims to establish a European research infrastructure for advanced computing technologies. Through close collaboration of leading European research institutes, industry and application partners, a European supply chain for materials and production processes for solid-state qubits will be established. This will create a European ecosystem to bring solid-state qubits—such as superconducting Josephson junctions—into application.
Fraunhofer IAF contributes its expertise and infrastructure in the field of low-temperature measurement technology, targeted at the investigation of the variability of superconducting layers. This gives European companies, especially SMEs and start-ups, access not only to the necessary know-how but also to state-of-the-art test and characterization equipment and thus to key components for the development of quantum computing hardware.
Nikola David Komerički summarizes the features, advantages, and applications of the new cryogenic wafer prober for the automated characterization of qubit devices. Fraunhofer IAF has commissioned the facility in 2023.
