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…

Entanglement of a Quantum Optical Elliptic Vortex
Abir Bandyopadhyay, Shashi Prabhakar, Ravindra Pratap Singh
We calculate the entanglement of a generalized elliptical vortex formed by quantized radiation field, using Wigner quasiprobability distribution function for such states. We find a…
