  text: Spins in semiconductor quantum dots have been considered as prospective quantum
    bit excitations. Their coupling to the crystal environment manifests itself in
    a limitation of the spin coherence times to the microsecond range, both for electron
    and hole spins. This rather short-lived coherence compared to atomic states asks
    for manipulations on timescales as short as possible. Due to the huge dipole moment
    for transitions between the valence and conduction band, pulsed laser systems
    offer the possibility to perform manipulations within picoseconds or even faster.
    Here, we report on results that show the potential of optical spin manipulations
    with currently available pulsed laser systems. Using picosecond laser pulses,
    we demonstrate optically induced spin rotations of electron and hole spins. We
    further realize the optical decoupling of the hole spins from the nuclear surrounding
    at the nanosecond timescales and demonstrate an all-optical spin tomography for
    interacting electron spin sub-ensembles.
