Integration of Optical Ground Stations for satellite-based Quantum Key Distribution into a quantum network

IQC Seminar - Stefanie Haeusler, Department of Optical Satellite Links, Institute of Communications and Navigation, Germany

Quantum Key Distribution (QKD) is a promising method to guarantee future-proof, information theoretic security. Since optical fibers have an exponential loss with distance, satellite-based QKD solutions are being developed in order to realize long-distance links. Therefore, Optical Ground Stations for QKD (QKD-OGS) need to be designed to enable quantum communication with satellites. Different link configurations will result in different integration options of the QKD-OGS in the terrestrial fiber network and therefore impact its performance. Applicable integration options are identified and discussed.
