Production of the Superposition of Nonlinear Coherent States and Entangled Nonlinear Coherent States
Amir Karimi, Mohammad Kazem Tavassoly · Communications in Theoretical Physics · 2015
In this paper, by using the parity operator as well as the nonlinear displacement-type operator, we define new operators which by the action of them on the vacuum state of the radiation field, superposition of two nonlinear coherent states and two-mode entangled nonlinear coherent states are generated. Also, we show that via the generalization of the presented method, the superposition of more than two nonlinear coherent states and n-mode entangled nonlinear coherent states can be generated.
