Despite the impressive development progress concerning the superconducting qubit platform in Germany and Europe, research and development challenges still need to be addressed. This includes scalability to higher number of qubits and faster learning cycles to speed up the performance improvement. Only by solving these challenges technological sovereignty and the access to competitive quantum computers at a national and European level are ensured.
The efforts within the project QuantumSPICE can be categorized into three topics: (1) scaling and reproducibility, (2) materials development, and (3) development of fast in-line characterization. 
The scaling efforts involve investigating frequency targeting and reducing the qubit's footprint. Another goal is to research and optimize material combinations and new fabrication strategies. The focus here is on improving the performance of Josephson junctions. The partners are investigating different material systems for future integration and scaling. Within the consortia, new innovative solutions for rapid in-line characterization at room temperature and low temperatures are being investigated to ensure that learning cycles can be sped up.
