The Einstein-Podolsky-Rosen paradox and the Bell theorem

TL;DR

This paper discusses the Bell theorem, demonstrating that the principles of locality and reality cannot both be maintained within quantum theory, highlighting fundamental nonlocality in quantum mechanics.

Contribution

It provides an analysis of the Bell theorem, clarifying the incompatibility of locality and realism in quantum physics.

Findings

Bell theorem proves nonlocality in quantum mechanics

Locality and realism cannot both be true in quantum theory

Quantum entanglement challenges classical notions of locality

Abstract

We will discuss here the Bell theorem, which shows that "locality" and "reality" are together inconsistent with quantum theory.
