Optical vortex produced by Single Photon Subtraction from two mode squeezed state Produces Maximum Entanglement

TL;DR

This paper demonstrates that single photon subtraction from two-mode squeezed states yields maximum entanglement, highlighting its non-classical nature compared to multiple photon subtractions.

Contribution

It shows that single photon subtraction produces the highest entanglement, advancing understanding of non-classical effects in quantum state manipulation.

Findings

Single photon subtraction yields maximum entanglement.

Multiple photon subtractions produce less entanglement.

Single photon subtraction is more non-classical than multiple photon subtractions.

Abstract

In this article we report that the entanglement produced by single photon subtraction is maximum, by studying the entanglement of multi photon subtraction from two mode squeezed states. We argue that the single photon subtraction produces maximum entanglement as it is more non-classical in nature than many photon subtractions
