Measurement of time correlations for quantum-mechanical systems

Creators

Abstract

Measurements that are of limited accuracy, are incomplete, or require a finite time to make do not generally permit one to construct a wave function for describing a physical system. The use of such partial information to predict the results of subsequent measurements is studied here. There are several practical applications of this problem, including the use of the autocorrelation function for a particle counter in a scattering experiment.

Wigner for several conversations in which he suggested that the overlap function (2.7) might be a maximum for "morally best" observations.
