Summary:We develop some general results on the properties of the reachable
sets for right invariant bilinear systems with state varying on compact
Lie groups. The main results consist of a characterization of the set of
states reachable in arbitrary time from the identity of the group. This,
under suitable assumptions, is proved to be a Lie subgroup of the
underlying Lie group. We apply these results to the analysis of the
controllability of particles with spin. For these systems we also obtain
estimates of the time after which every state is reachable from the
identity. The results are motivated by the problem of controlling a
two-level quantum system in implementations of quantum computers
