摘要：

We report an all-optical realisation of a quantum relay experiment at a telecom wavelength. The main idea relies on utilizing a picosecond 2.5 GHz repetition rate telecom laser as a master clock to allow, thanks to dedicated distribution channels, the generation of synchronized entangled pairs of photons at remote locations. This is a necessary condition for achieving a reliable quantum relay function over a significant distance. We report a two-photon interference visibility at the relay station greater than 99%, validating our synchronization scheme at optical table scale, and paving the way for an extend of the communication distance.
