    "abstract": "Using 2 km of standard telecom optical fibres, we teleport qubits carried by\nphotons of 1310 nm wavelength to qubits in another lab carried by a photons of\n1550 nm wavelength. The photons to be teleported and the necessary entangled\nphoton pairs are created in two different non-linear crystals. The measured\nmean fidelity is of 81.2 %. We discuss how this could be used as quantum\nrepeaters without quantum memories.",
