We consider the problem of impurities placed on the semi-major axis of an elliptic quantum corral interacting with the confined corral electrons. The time evolution of the system was solve exactly and we study the dependence of spin variables, like the spin squeezing factor, an the total spin alignment of the impurities. The results suggest that such a system exhibits some of the characteristic features of a qubit, concerning the persistence of the orientation and squeezing of a component of the total spin.
