How Quantum is the Classical World?

TL;DR

This paper explores the boundary between classical and quantum phenomena by proposing experimental methods and statistical tools to test local realism and complementarity in classical measurements.

Contribution

It introduces a novel experimental design and statistical approach to analyze classical measurements for potential violations of local realism.

Findings

Proposed a method to perform classical measurements without ontological complementarity.

Developed a statistical approach to detect violations of local realism.

Provided a framework to distinguish genuine quantum effects from classical data.

Abstract

It has been experimentally confirmed that quantum physical phenomena can violate the Information Bell Inequalities. A violation of the one or the other of these Information Bell Inequalites is equivalent to a violation of local realism meaning that either objectivity or locality, or both, do not hold for the phenomena under investigation. We propose (1) an experimental design for carrying out classical measurements in the absence of ontological complementarity; (2) a rational way to extract epistemologically complementary (pseudocomplementary) data from it; (3) a statistical approach which can reject stochastic and/or suspected violations of local realism in measurements of such data.
