Fraunhofer Institute for Integrated Systems and Device Technology IISBWe pioneer the development of SiC and diamond for quantum applications. Our research covers the entire value chain, from material development, the creation of color centers, design and processing of quantum devices, and their integration into system demonstrators. One focus is on the deterministic generation of high quality color centers with long spin coherence on a nanometer scale. Special characterization set-ups are available to characterize the quantum systems. Furthermore, we use tailored simulation tools to support the material and technology development.
