Information measures and classicality in quantum mechanics
We study information measures in quantum mechanics, with the particular emphasis on providing a quantification of the notion of predictability and classicality. Our primary tool is the Shannon Wehrl entropy I. We give a precise criterion for phase space classicality of states and argue that in view of this a) I provides a good measure for the degree of deviation from classicality in closed syst...
متن کاملClassicality in Quantum Mechanics
In this article we propose a solution to the measurement problem in quantum mechanics. We point out that the measurement problem can be traced to an a priori notion of classicality in the formulation of quantum mechanics. If this notion of classicality is dropped and instead classicality is defined in purely quantum mechanical terms the measurement problem can be avoided. We give such a definit...
متن کاملQuantum Darwinism: Entanglement, branches, and the emergent classicality of redundantly stored quantum information
We lay a comprehensive foundation for the study of redundant information storage in decoherence processes. Redundancy has been proposed as a prerequisite for objectivity, the defining property of classical objects. We consider two ensembles of states for a model universe consisting of one system and many environments: the first consisting of arbitrary states, and the second consisting of “singl...
متن کاملEmergence of Classicality in Quantum Phase Transitions
We show that classicality emerges during quantum phase transtions due to parametric interactions without coupling to environments. The Wigner functions are explicitly calculated for the Gaussian vacuum, number, and thermal states of a free scalar field that describes the spinodal instability regime. The Wigner functions are sharply peaked around their classical trajectories during the phase tra...
