    "abstract": "Elementary 2-dimensional quantum states (qubits) encoded in 1300 nm\nwavelength photons are teleported onto 1550 nm photons. The use of\ntelecommunication wavelengths enables to take advantage of standard optical\nfibre and permits to teleport from one lab to a distant one, 55 m away,\nconnected by 2 km of fibre. A teleportation fidelity of 81.2 % is reported.\nThis is large enough to demonstrate the principles of quantum teleportation, in\nparticular that entanglement is exploited. This experiment constitutes a first\nstep towards a quantum repeater.",
