Zusammenfassung:The present disclosure pertains to a system and a method for quantum key distribution. The system comprises a first data processing device (10); a second data processing device (11); and a transmission line (12) between the first data processing device (10) and the second data processing device (11). The transmission line (12) comprises an inner optical fiber (20), a shielding layer (21) surrounding the inner optical fiber (20), and an outer optical fiber (22) surrounding the shielding layer (21). The first data processing device (10) and the second data processing device (11) are configured to determine a shared key by quantum key distribution via quantum signals along the inner optical fiber (20). The system is configured to determine outer signal losses along the outer optical fiber (22).
