  Using 2 km of standard telecom optical fibres, we teleport qubits carried by
photons of 1310 nm wavelength to qubits in another lab carried by a photons of
1550 nm wavelength. The photons to be teleported and the necessary entangled
photon pairs are created in two different non-linear crystals. The measured
mean fidelity is of 81.2 %. We discuss how this could be used as quantum
repeaters without quantum memories.
