Teleportation of superposed nonlinear coherent states

Abstract

In this paper, we study the teleportation of nonlinear coherent cat states assuming even and odd nonlinear quasi-Bell states as the channel. Odd nonlinear quasi-Bell states are shown to be maximally entangled independent of the coherent parameter and also nonlinear function but the entanglement of the even nonlinear coherent states depends on the parameters involved. Subsequently, the teleportation probability is evaluated for some nonlinear functions. Our research reveals that when even and odd nonlinear quasi-Bell states are assumed as the quantum channel, the probabilities for successful teleportation are oppositely varied by increasing coherent parameter. For the special case of nonlinear harmonious states, the teleportation probability is a decreasing (increasing) function of the coherent parameter if even (odd) nonlinear quasi-Bell state is used as the channel.
