Project information

The Thuringian Innovation Centre InQuoSens intends to use the current call for proposals from the Thüringer Aufbaubank (TAB) for funding the E-PhoQuant research group to strategically strengthen its position in the research and innovation field of quantum technologies. The application of quantum physical phenomena will revolutionise information transmission and processing in terms of data security. Research in the field of tap-proof encryption using quantum key distribution (QKD) is leading the way. The communication-technological foundations required for this to hear the key transmission rates are being developed within the framework of the TAB FastPhoton research groups. This includes increasing the drive frequencies of photon sources, reducing transmission losses of quantum mechanical states and improving the time resolution of detectors. The focus is not on their miniaturised integration as a basis for acceptance in e.g. mobile systems. This is where the E-PhoQuant research group comes in. Within the framework of the research, a heterogeneous integration solution for the realisation of compact quantum optical components and modules is to be developed. Based on a highly integrated combined microelectronic/optical system developed at the InQuoSens site in Ilmenau, it will be possible to create such a system. This system approach is not only aimed at miniaturisation, but also builds on wafer-level structuring technologies that are a prerequisite for future transfer to industry.
