Abstract

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