The aim of the project “Development of high-performance transmission components for quantum-safe communication over fiber-optic lines in metro and wide-area networks” (DE-QOR) is to further develop existing QKD approaches based on coherent optical transmission technology (continuous variable QKD, CV-QKD). The advantage here is that existing infrastructure can be used. Central components on the transmitter and receiver side are to be developed and integrated into compact systems. This includes both optical modules and the associated electronics, whose firmware can be continuously updated and optimized by remote maintenance. The aim is to develop transmission links in urban areas with a length of more than 80 kilometers. The researchers want to achieve the highest possible transmission speeds. This is to be achieved by analyzing and optimizing the analog and digital subsystems in order to achieve a key generation rate that can be used to encrypt a large number of channels. In addition, the components will be tested for security aspects, for example regarding attack possibilities. The project partners are also carrying out preliminary work to facilitate standardization and certification after the end of the project and thus open up the widest possible circle of users.
