The paper reports on the entangled-state quantum cryptography system practical operation. The full key generation protocol was performed in real-time over a fiber bundle of 1.45 km length, installed for this experiment in the Vienna sewage system. The generated quantum key was immediately handed over and used by a secure communication application of order for remittance.
