Quantum Information of a Four-Level Tripod-Type Atom in Motion Interacting with a Deformed Binomial Field in the Presence of a Non-Linear Medium

This paper investigates the interaction dynamics of a four-level tripod-type atomic system coupled to a q-deformed binomial field state within a Kerr-medium. The interaction model incorporates time-dependent coupling parameter and detuning parameter, providing a more adaptable framework for describing atom-field interactions. Special focus is placed on examining how the q-deformation, time-dependent coupling parameter, detuning parameter and Kerr nonlinearity affect the system's fidelity properties and linear entropy dynamics. Our results demonstrate that the effects of the considered parameters have a significant impact on atom-field entanglement and fidelity. These findings offer valuable insights into controlled quantum systems, with potential applications in quantum information processing and nonlinear quantum optics.

Quantum Control of the Time-Dependent Interaction between a Three-Level $Ξ$-Type Atom and a Two-Mode Field with Damping Term

The purpose of this paper is to investigate some properties through a three-level $Ξ$-type atom interacting with a two-mode field. We test this system in the presence of the photon assisted atomic phase damping, detuning parameter and Kerr nonlinearity. Also, the coupling parameter modulated to be time-dependent. The problem solution of this model is given by using the Schrődinger equation when the atom and the field are initially prepared in the excited state and coherent state, respectively. We used the results to calculate some aspects such as atomic population inversion and concurrence. The results show that the time-dependent coupling parameter and the detuning parameter can be considered as a quantum control parameters of the atomic population inversion and quantum entanglement in the considered model.

Phase Distribution Properties of a Moving Five-Level (Inverted Y)-Type Atom in the Presence of a Non-linear Medium

In this paper, we study the nonlinear kerr effect in an inverted Y-type five-level atom moving through an open cavity. Under realistic parameters, we show that the kerr-medium affects the atomic population inversion and the phase probability distribution. A remarkable feature of the present model is that the kerr nonlinearity with a multi-level atom allows for a large detection of the system dynamics. These results offer new possibilities for controlling the system dynamics using the time-dependent interaction.
