We consider time dependent spin variables of impurities placed inside a quantum corral. In particular we have studied the dependence of spin observables, like the the spin squeezing factor and total spin alignment for impurities, located on the semi-major axis of an elliptic quantum, interacting with the electrons confined in the corral. 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.
