    "abstract": "We report the observation of entanglement between a single trapped atom and a\nsingle photon at a wavelength suitable for low-loss communication over large\ndistances, thereby achieving a crucial step towards long range quantum\nnetworks. To verify the entanglement we introduce a single atom state analysis.\nThis technique is used for full state tomography of the atom-photon qubit-pair.\nThe detection efficiency and the entanglement fidelity are high enough to allow\nin a next step the generation of entangled atoms at large distances, ready for\na final loophole-free Bell experiment.",
