Delayed Choice Between Purely Classical States

Abstract

It is argued that Wheeler's insightful idea of delayed choice experiments may be explored at a classical level, arising naturally from number-theoretical conjugacies always necessarily present in the equations of motion. For simple and representative systems, we illustrate how to cast the equations of motion in a form encoding all classical states simultaneously through a ``state parameter''. By suitably selecting the parameter one may project the system into any desired classical state.
