Maximal entanglement from photon-added nonlinear coherent states via unitary beam splitters

K. Berrada

Published Feb 1, 2014• 4 citations

Abstract

In this paper, we construct photon-added f -deformed coherent states (PA f -DCSs) for nonlinear bosonic fields by discussing Klauder's minimal set of conditions required to obtain coherent states. Using this set of nonlinear states, we propose a very useful scheme for generating the maximal amount of entanglement via unitary beam splitters for different strength regimes of the input field α, deformation q and excitation number m . Therefore, the possibility to create highly entangled states and to control the entanglement is proposed. Moreover, the condition for a maximal and separable output beam state is obtained. Finally, we examine the statistical properties of the PA f -DCSs through the Mandel parameter and exploit a connection between this quantity and the behavior variation of the output state entanglement. Our result may open new perspectives in different tasks of quantum information processing.

Beam splitter entangler for nonlinear bosonic fields

S. Abdel‐Khalek, K. Berrada, C. H. Raymond Ooi

Some years ago Katriel and Solomon [1] described applications to the characterization of the photon statistics of nonideal lasers, nonclassical light, and deformed photon states using f -deformed coherent states. In this letter, we study the effect of a beam splitter on these nonlinear coherent states. We find that these states are useful for generating quantum entanglement as the deformation parameter gets farther form the unity and for strong input field regimes. The results are confirmed through the Werhl entropy.

Photon-Added Deformed Peremolov Coherent States and Quantum Entanglement

K. Berrada

In the present article, we build the excitedcoherent states associated with deformed su(1,1) algebra (DSUA), called photon-added deformed Perelomov coherent states (PA-DPCSs). The constructed coherent states are obtained by using an alterationof the Holstein–Primakoff realization (HPR) for DSUA. A general method to resolve of the problem of the unitary operator was developed for these kinds of quantum states. The Mandel parameter is considered to examine the statistical properties of PA-DPCSs. Furthermore, we offer a physical method to generate the PA-DPCSs in the framework of interaction among fields and atoms. Finally, we introduce the concept of entangled states for PA-DPCSs and examine the entanglement properties for entangled PA-DPCSs.

Photon-added deformed spin coherent states and bipartite entanglement

K. Berrada, A. Sabik, Hichem Eleuch

In present manuscript, we build the photon-added deformed spin coherent states (PA-DSCSs) according to deformed spin algebra (DSA). We present the way for solving the unity operator problem and we give the solution for some particular cases. The obtained states are developed through the Holstein-Primakoff (HP) realization of the DSA. The statistical features of the obtained coherent states are examined through the variation of the Mandel’s parameter. By using the PA-DSCSs, we investigate the bipartite entanglement with respect to different parameters of these states.

Photon-added nonlinear coherent states for a one-mode field in a Kerr medium

R. Román-Ancheyta, Carlos A. González-Gutiérrez, J. Récamier

We construct deformed photon-added nonlinear coherent states (DPANCSs) by application of the deformed creation operator upon the nonlinear coherent states obtained as eigenstates of the deformed annihilation operator and by application of a deformed displacement operator upon the vacuum state. We evaluate some statistical properties like the Mandel parameter, Husimi, and Wigner functions for these states and analyze their differences; we give closed analytical expressions for them. We found a profound difference in the statistical properties of the DPANCSs obtained from the two abovementioned generalizations.

Comment on 'Entanglement of photon-added nonlinear coherent states via beam splitter'

Hadiah Bint Monir, Shahid Iqbal

Beam splitter mediated entanglement of nonlinear photon-added coherent states was studied by Honarasa, Bagheri and Gharaati [1]. We believe that this work contains errors in numerical computations of linear entropy and Mandel parameter which lead to wrong conclusions. We point out the possible errors and describe the necessary corrections. The conclusions based on our arguments are in complete agreement with previously published literature.

Photon added coherent states for nonharmonic oscillators in a nonlinear Kerr medium

M. A. Al-Rajhi

In this paper, we construct the photon-added anharmonic oscillators coherent states (PA-AOCSs) using generalized Heisenberg algebras. Klauders minimal set of conditions required to obtain the coherent states are satisfied. The statistical properties of these states are investigated through the Mandel's parameter in terms of the variables involved in the states. It is shown that these coherent states are useful for describing the states of real and ideal lasers in terms of different parameters. These features make these states good candidatures for implementation of schemes in different tasks of quantum optics and information.
