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

Abir Bandyopadhyay, Anindya Banerji, R. P. Singh

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
