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

Wigner distribution function and entanglement of generalized quantum optical vortex
Abir Bandyopadhyay, Shashi Prabhakar, R. P. Singh
We calculate the Wigner (quasi)probability distribution function of the quantum optical elliptical vortex (QEV), generated by coupling squeezed vacuum states of two modes. The coup…
