Violation of Bell's inequalities in a quantum realistic framework

TL;DR

This paper examines a quantum realistic interpretation of Bell's inequality violations, emphasizing a non-local but action-at-a-distance-free framework consistent with recent loophole-free experiments.

Contribution

It introduces a quantum realism framework attributing properties jointly to systems and contexts, offering a philosophically meaningful alternative to classical realism.

Findings

Bell inequality violations are compatible with a non-local quantum realism

The framework avoids action-at-a-distance despite non-local correlations

It aligns with recent loophole-free Bell test results

Abstract

We discuss the recently observed "loophole free" violation of Bell's inequalities in the framework of a physically realist view of quantum mechanics, which requires that physical properties are attributed jointly to a system, and to the context in which it is embedded. This approach is clearly different from classical realism, but it does define a meaningful "quantum realism" from a general philosophical point of view. Consistently with Bell test experiments, this quantum realism embeds some form of non-locality, but does not contain any action at a distance, in agreement with quantum mechanics.
