EPR's reality criterion and quantum realism

TL;DR

This paper demonstrates that EPR's reality criterion conflicts with quantum mechanics, revealing non-locality and non-realism, and shows that certain inequalities are violated under locality assumptions.

Contribution

It provides a novel analysis of EPR's criterion, highlighting its contradictions with quantum mechanics and the implications for locality and realism.

Findings

Violation of a one-particle inequality under locality

EPR-realism is not Lorentz invariant

Quantum mechanics is both non-local and non-realistic

Abstract

We show that EPR's criterion of reality leads to contradictions in quantum mechanics. When locality is assumed, an inequality involving only one particle is violated, while when parameter and outcome dependence are assumed, EPR-realism is shown to be not Lorentz invariant. Quantum mechanics is both non-local and non-realistic.
