title: Young's experiment and the finiteness of information.
abstract: Young's experiment is the quintessential quantum experiment. It is argued here that quantum interference is a consequence of the finiteness of information. The observer has the choice of whether that information manifests itself as path information or in the interference pattern or partly in both to the extent defined by the finiteness of information.
