Many Worlds Model resolving the Einstein Podolsky Rosen paradox via a Direct Realism to Modal Realism Transition that preserves Einstein Locality

TL;DR

This paper presents a many worlds model that resolves the EPR paradox by transitioning from direct realism to modal realism, maintaining locality while reproducing quantum correlations.

Contribution

It introduces a simple classical local realistic model that, through a natural step, becomes a quantum model consistent with observed probabilities, emphasizing a shift from direct to modal realism.

Findings

The model starts as a classical local realistic model.

A single step transforms it into a quantum model.

The approach preserves locality while reproducing quantum correlations.

Abstract

The violation of Bell inequalities by quantum physical experiments disproves all relativistic micro causal, classically real models, short Local Realistic Models (LRM). Non-locality, the infamous "spooky interaction at a distance" (A. Einstein), is already sufficiently 'unreal' to motivate modifying the "realistic" in "local realistic". This has led to many worlds and finally many minds interpretations. We introduce a simple many world model that resolves the Einstein Podolsky Rosen paradox. The model starts out as a classical LRM, thus clarifying that the many worlds concept alone does not imply quantum physics. Some of the desired non-locality, e.g. anti-correlation at equal measurement angles, is already present, but Bell's inequality can of course not be violated. A single and natural step turns this LRM into a quantum model predicting the correct probabilities. Intriguingly, the crucial step does obviously not modify locality but instead reality: What before could have still been a direct realism turns into modal realism. This supports the trend away from the focus on non-locality in quantum mechanics towards a mature structural realism that preserves micro causality.
