    "abstract": "Coherent control of collective spontaneous emission in an extended atomic\nensemble resonantly interacting with single-photon wave packets is analyzed. A\nscheme for coherent manipulation of collective atomic states is developed such\nthat superradiant states of the atomic system can be converted into subradiant\nones and vice versa. Possible applications of such a scheme for optical quantum\nstate storage and single-photon wave packet shaping are discussed. It is shown\nthat also in the absence of inhomogeneous broadening of the resonant line,\nsingle-photon wave packets with arbitrary pulse shape may be recorded as a\nsubradiant state and reconstructed even although the duration of the wave\npackets is larger than the superradiant life-time. Specifically the\napplicability for storing time-bin qubits, which are used in quantum\ncryptography is analyzed.",
