Abstract: In an effort to resolve the quantum measurement problem, Wojciech Zurek suggests that there is no collapse of the wavefunction, but rather an apparent collapse due to the effects of environmental decoherence. This emergence of an objective classical reality results because only preferred states, called pointer states, are allowed to proliferate through the environment as a result of what Zurek calls quantum Darwinism. Interaction with the environment also leads to a transformation property called envariance, exhibited by pure entangled states. Zurek uses envariance to derive Born’s rule, thus justifying the use of reduced density matrices in the development of his theory. The potential impact of Zurek’s theory on the foundations of quantum mechanics demands that it undergo intense scrutiny, including experimental verification. One such experiment has been performed using entangled photons, and an analog experiment using matter will be presented.
