Entanglement measure using Wigner function: case of generalized vortex state formed by multiphoton subtraction
arXiv:1304.2887 · doi:10.1016/j.optcom.2014.05.035
Abstract
The negativity of the Wigner function is discussed as a measure of the non classicality and the quantum interference pattern obtained therein as a possible measure of the entanglement between the two modes of the vortex states. This measure of entanglement is compared with the results obtained from concurrence.
