    "abstract": "We present a full implementation of a quantum key distribution system using\nenergy-time entangled photon pairs and functioning with a 30km standard telecom\nfiber quantum channel. Two bases of two orthogonal states are implemented and\nthe setup is quite robust to environmental constraints such as temperature\nvariation. Two different ways to manage chromatic dispersion in the quantum\nchannel are discussed.",
