摘要：

We present a full implementation of a quantum key distribution system using energy-time entangled photon pairs over a 30 km standard telecom fiber quantum channel. Two bases of two orthogonal states are implemented and the set-up is shown to be robust to environmental constraints such as temperature variation. Two different ways to manage chromatic dispersion in the quantum channel are discussed.
