    "abstract": "We report on the coherent quantum state transfer from a two-level atomic\nsystem to a single photon. Entanglement between a single photon (signal) and a\ntwo-component ensemble of cold rubidium atoms is used to project the quantum\nmemory element (the atomic ensemble) onto any desired state by measuring the\nsignal in a suitable basis. The atomic qubit is read out by stimulating\ndirectional emission of a single photon (idler) from the (entangled) collective\nstate of the ensemble. Faithful atomic memory preparation and read-out are\nverified by the observed correlations between the signal and the idler photons.\nThese results enable implementation of distributed quantum networking.",
