In this thesis we study some problems of controllability, confinement, and transmission for the Schroödinger equation for some choices of Riemannian manifolds. We present a controllability test for the bilinear discrete spectrum Schrödinger equation that allows to conclude the approximate controllability of the system by checking the controllability of overlapping finite-dimensional projections and a weak spectral condition of the infinite-dimensional system. This test can be applied in particular to study the controllability problem for the quantum evolution on Riemannian manifolds, and it is particularly suited for systems with high degree of symmetry (and hence, severe spectral degeneracies). We specialize the technique to the Schrödinge...
