摘要: We present an entangled-state quantum cryptography system that operated for the first time in a real-world application scenario. The full key generation protocol was performed real-time between two distributed embedded hardware devices, which were connected by 1.45 km of optical fiber, installed this experiment Vienna sewage system. generated immediately handed over and used secure communication application.
