Complementarity in the doubleslit experiment: Quantum nonseparability and a quantitative statement of Bohr's principle
Abstract
A detailed analysis of Einstein's version of the doubleslit experiment, in which one tries to observe both wave and particle properties of light, is performed. Quantum nonseparability appears in the derivation of the interference pattern, which proves to be surprisingly sharp even when the trajectories of the photons have been determined with fairly high accuracy. An informationtheoretic approach to this problem leads to a quantitative formulation of Bohr's complementarity principle for the case of the doubleslit experiment. A practically realizable version of this experiment, to which the above analysis applies, is proposed.
