Quantum Correlations in Classical Systems

TL;DR

This paper demonstrates that classical systems can exhibit quantum-like correlations and Bell violations, challenging traditional interpretations of quantum principles and emphasizing ensemble effects.

Contribution

It shows classical fluid splitters can produce quantum correlations and Bell violations, supporting the Correspondence Principle and questioning existing notions of Local Realism.

Findings

Classical fluid splitters mimic quantum energy redistribution patterns.

Classical systems can exhibit Tsirelson-type Bell violations.

Quantum-like correlations arise from ensemble effects, not intrinsic properties.

Abstract

A classical fluid splitter produces the same patterns of energy redistribution as a Stern-Gerlach quantum device, with rotationally invariant coefficients of correlation between molecular paths. Alternative settings express a cosine squared relationship, leading to Tsirelson-type Bell violations with outcome independence. This result confirms the Correspondence Principle of quantum mechanics, where individual detection events express system-level properties according to Born's Rule. Kochen-Specker contextuality and Bell Locality are not formally contradicted, but their interpretation is in question. Current definitions of Local Realism are limited to intrinsic particle properties. In contrast, quantum-like correlations require the acknowledgement of ensemble effects on dynamically inseparable entities, even when those entities are observed one at a time.
