Abstract:
Presented is the first successful integration of coherent Quantum Communications into standard telecommunication infrastructure, spanning 254 km between Frankfurt and Strasbourg. Using the Twin-Field Quantum Key Distribution protocol, a secure key exchange of 110 bit/s was achieved. This milestone demonstrates feasibility and compatibility of coherent quantum communications with existing infrastructure, advancing quantum internet prospects.
