Abstract
A feasible experimental proposal to realize a non-dispersive quantum pendulum is presented. The proposed setup consists of an ultracold atomic cloud, featuring attractive interatomic interactions, loaded into a tilted ring potential. The classical and quantum domains are switched on by tuned interactions, and the classical dynamical stabilization of unstable states, i.e. {\it a la} Kapitza, is shown to be driven by quantum phase imprinting. The potential use of this system as a gravimeter is discussed.
