Entanglement of a Quantum Optical Elliptic Vortex
arXiv:1010.3911 · doi:10.1016/j.physleta.2011.03.044
Abstract
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 critical squeezing parameter above which the entanglement is less for higher vorticity, which is counter intuitive.
