Entropy and Entanglement of Moving Two Atoms in a Squeezed Field via Four-Photon Process

Abstract

In this paper, the entanglement between two atoms and squeezed field via four photon process is investigated. The dynamical behavior of the entanglement between two atoms and a squeezed field is analyzed. In particular, the effects of the atomic motion, the initial atomic state and the field squeezing are examined. A high amount of entanglement is generated by increasing the field squeezing. Furthermore, we show that a sudden death and sudden birth emerge when the moving atoms are initially prepared in the excited state.

The entanglement of two moving atoms interacting with a single-mode field via a three-photon process

Chao Wu, Mao-Fa Fang

In this paper, the entanglement of two moving atoms induced by a single-mode field via a three-photon process is investigated. It is shown that the entanglement is dependent on the category of the field, the average photon number N , the number p of half-wave lengths of the field mode and the atomic initial state. Also, the sudden death and the sudden birth of the entanglement are detected in this model and the results show that the existence of the sudden death and the sudden birth depends on the parameter and the category of the mode field. In addition, the three-photon process is a higher order nonlinear process.

Sudden Death and Sudden Birth of Entanglement Between Two Atoms Successively Passing Fock State Field

Gao De-ying

The dynamics of entanglement of two initially separate atoms passing through a cavity one after another is studied by the negativity method.The effects of the two atom initial states and the field in the fock state on the time evolution of atom-atom entanglement are examined.The phenomenon of sudden birth and death of entanglement occurs when the photon number in the fock state is not zero and the phenomenon will change with the two atom initial states and the photon number.

Aspects of Entropy Squeezing and Entanglement for Moving Two-Level Atom in Presence of Finite Trio Coherent State

S. I. Ali, Ahmed M. Mosallem, Tarek Emam

In this paper, we investigate the entanglement of the interaction of three modes of radiation field with moving and unmoving two-level atom. The time evolution of the von Neumann entropy, entropy squeezing and marginal atomic Wehrl entropy is investigated. The marginal atomic Wehrl entropy as squeezing indicator of the entanglement of the system is suggested. The results beacon the important roles played by both the atomic motion parameters in the evolution of entanglement, entropy squeezing and marginal atomic Wehrl entropy. Using special values of the photon number of transition and atomic motion parameter, the entanglement phenomena of sudden death and long living entanglenment can be appeared. The results show that there is atomic motion monotonic harmonization atomic Wehrl entropy (WE). It is illustrated that the amount of the above-mentioned phenomena can be tuned by controlling the evolved parameters appropriately.

Study on sudden death of the entanglement between an isolated atom and an atom inside a bimodal cavity

Liao Qing-Hong

The entanglement dynamics of two atoms initially in an entangled state system interacting with a bimodal field is investigated by making use of the concurrence and linear entropy.The effect of the initial entanglement degree of two atoms and the cavity field on the time evolution of concurrence is analyzed.The results show that the phenomenon of sudden death of the entanglement between two atoms occurs.The length of the death time interval is independent of the initial entanglement degree of two atoms.However,the death time depends on the initial entanglement degree of the cavity field.The atom and the field are entangled during all the evolution process.

Quantum entanglement in a system of two moving atoms interacting with a single mode field

A.‐S. F. Obada, H. A. Hessian, Mostafa Hashem

We investigate the quantum entanglement in a system of two moving atoms interacting with a single mode field. An analytical solution for this system is obtained when both atoms are initially in the excited state and the field is in a coherent state. We study the effects of atomic motion and other parameters on the entanglement of the system and different bipartite partitions of the system (field–two atoms, atom–(field+atom)) through the tangles. The effect of atomic motion on the amount of entanglement between atoms and the field is also evaluated through the negativity. The results show that atomic motion leads to the periodic death and anabiosis of the entanglement between two moving atoms, and the time of the death and the amplitude of the anabiosis of the entanglement between two moving atoms depend on the coupling constant of two moving atoms and the parameter of the mode field.

Entanglement and Entropy Squeezing for Moving Two Two-Level Atoms Interaction with a Radiation Field

S. Abdel‐Khalek, Eied Mahmoud Khalil, Beida Alsubei +3 more

In this paper, we analyzed squeezing in the information entropy, quantum state fidelity, and qubit-qubit entanglement in a time-dependent system. The proposed model consists of two qubits that interact with a two-mode electromagnetic field under the dissipation effect. An analytical solution is calculated by considering the constants for the equations of motion. The effect of the general form of the time-dependent for qubit-field coupling and the dissipation term on the temporal behavior of the qubit-qubit entanglement, quantum state fidelity, entropy, and variance squeezing are examined. It is shown that the intervals of entanglement caused more squeezing for the case of considering the time-dependent parameters. Additionally, the entanglement between the qubits became more substantial for the case of time dependence. Fidelity and negativity rapidly reached the minimum values by increasing the effect of the dissipation parameter. Moreover, the amount of variance squeezing and the amplitude of the oscillations decreased considerably when the time dependence increased, but the fluctuations increased substantially. We show the relation between entropy and variance squeezing in the presence and absence of the dissipation parameter during the interaction period. This result enables new parameters to control the degree of entanglement and squeezing, especially in quantum communication.
