Аннотация: The report will be devoted to satellite quantum key distribution (QKD), a direction in quantum communication that allows using a satellite to organize a secure communication channel on a global scale in order to share cryptographic keys between users. Based on the recent research of our group [1], the results of establishing a quantum-secured link between the Zvenigorod and Nanshan ground stations using the Micius satellite will be presented. Moreover, we validate the simulation outcomes of our QKD model for the developed realistic ground station using obtained experimental findings, which, as we believe, provide valuable insights on the applied side of the satellite-based QKD technology.
