Abstract

Entanglement is considered to be a quintessential quantum effect. We show however that, surprisingly, there exists a very close classical analog of quantum entanglement. We explicitly show how many results of entanglement manipulations give interesting new results in the classical setting. We also show how the classical results shed light upon the nature of the quantum ones, and lead to more intuitive proofs of some entanglement results.
