Description
Summary:We report on a realization of a fully automated 20km quantum key distribution system incorporating real time error correction and privacy amplification protocols carried out via the Internet. Dedicated security analysis against realistic attacks is used to optimize the system parameters in order to maximize the secrecy capacity for the communication over the 20km distance.
