Abstract

We study the evolution of a free ``Schrödinger cat'' state (a superposition of two coherent correlated states moving in opposite directions) using the formalism of the Wigner function. Two possible mechanisms to spatially separate the two states are considered: a ``quantum sling'' and a Paul trap that produces unstable motion. The numerical analysis shows how the two superposed states move away of each other, while keeping an interference term between them that is typical of quantum phenomena.
