Nonlinear displaced Kerr state and its nonclassical properties
Abstract
We construct a distinct class of nonlinear displaced Kerr state by application of the displacement operator upon a state which is prepared by sending the well-known photon-added coherent state through a normal Kerr medium. A sketch for the experimental set-up for preparing the state is suggested. We evaluate some statistical properties such as the photon number distribution, Mandel's parameter, Husimi- and Wigner functions, and quadrature squeezing, for the nonlinear displaced Kerr state, and then analyze the nonclassicality in terms of these standard parameters. We reduce the infinite-level problem to a truncated discrete two-level system by using low Kerr parameter approximation and then convert the generated nonclassicality into bipartite entanglement between the two modes of an output state of a linear optical device.
