Macroscopic randomness for quantum entanglement generation

TL;DR

This paper introduces a classical method for generating entangled light pairs in a macroscopic regime using basis randomness, challenging the traditional quantum-only understanding of entanglement.

Contribution

It presents a novel classical approach to produce entangled light pairs on demand, which traditionally required quantum superposition and microscopic regimes.

Findings

Classical basis randomness can generate entangled light pairs.

The method operates in a macroscopic regime, unlike traditional quantum methods.

This challenges the notion that entanglement is exclusively quantum.

Abstract

Quantum entanglement between two or more bipartite entities is a core concept in quantum information areas limited to microscopic regimes directly governed by Heisenberg uncertainty principle via quantum superposition, resulting in nondeterministic and probabilistic quantum features. Such quantum features cannot be generated by classical means. Here, a pure classical method of on-demand entangled light-pair generation is presented in a macroscopic regime via basis randomness. This conflicting idea of conventional quantum mechanics invokes a fundamental question about both classicality and quantumness, where superposition is key to its resolution.
