  abstract = 	{In this work, I study the quantum rotational motion of symmetric nanorotors and in particular how the non-linearity of the dynamics can be exploited for quantum experiments with orientational degrees of freedom. In absence of external torques the quantization of the angular momentum leads to a complete reappearance of the initial state at integer multiples of a quantum revival time. In the first part of the thesis, I propose an experimental scheme to observe these revivals for nanoparticles. Taking carbon nanotubes and silicone nanorods as examples, I discuss the experimental requirements for this set up and use numerical as well as semiclassical methods to simulate the expected revival signal. Subsequently, the effect of a permanent torque on the revival signal is investigated for planar and linear rotors using perturbation theory and semiclassical approximations, since an exact numerical calculation of the rotational dynamics becomes intractable. The last part focuses on interference effects at fractions of the revival time. The brief emergence of well-localized superposition states allows for an interferometric control of the rotational state by short weak laser pulses.},
