Anthropomorphic Quantum Darwinism as an explanation for Classicality

TL;DR

This paper explores how classical reality emerges from quantum systems through a form of Quantum Darwinism, emphasizing the evolution of stable information extraction and classical preconceptions.

Contribution

It introduces a model of two interacting particles illustrating how classical logic and perceptions arise from quantum correlations via a selection principle.

Findings

Classical preconceptions are the result of evolutionary processes.

Preferred bases like position emerge as stable information extraction methods.

The approach offers new insights into the quantum-to-classical transition.

Abstract

According to the so-called ``Quantum Darwinist'' approach, the emergence of ``classical islands'' from a quantum background is assumed to obey a (selection) principle of maximal information. We illustrate this idea by considering the coupling of two particles that interact through a position-dependent potential. This approach sheds a new light on the emergence of classical logics and of our classical preconceptions about the world. The distinction between internal and external world, the Cartesian prejudice according to which the whole can be reduced to the sum of its parts and the appearance of preferred representation bases such as the position is seen here as the result of a very long evolution and would correspond to the most useful way of extracting stable and useful information from the quantum correlations.
