Entanglement generation with deformed Barut-Girardello coherent states as input states in an unitary beam splitter
Document info: Pages 13, Figures 4.
Using linear entropy as a measure of entanglement, we investigate the entanglement generated via a beam splitter using deformed Barut-Girardello coherent states. We show that the degree of entanglement depends strongly on the $q$-deformation parameter and amplitude $Z$ of the states. We compute the Mandel $Q$ parameter to examine the quantum statistical properties of these coherent states and make a comparison with the Glauber coherent states. It is shown that these states are useful to describe the states of real and ideal lasers by a proper choice of their characterizing parameters, using an alteration of the Holstein-Primakoff realization.
