Optical vortex produced by Single Photon Subtraction from two mode squeezed state Produces Maximum Entanglement
arXiv:1210.1930
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
