Abstract

Abstract This paper presents a comprehensive investigation into the complex dynamics of optical tomography and quantum coherence within a nonlinear interaction system. The system under study is composed of an Ξ-type qutrit and a deformed cavity-field, analyzed for two distinct initial states: coherent states and even coherent states. Our analysis thoroughly considers the influence of intrinsic decoherence, a critical factor in understanding quantum system evolution. This study explores the remarkable sensitivity of optical tomography distributions (OTDs) to key parameters, including the initial state, evolution time, and the effects of a Kerr-like nonlinearity. We demonstrate that while coherent states initially appear classical, they display early-stage quantum interference due to their intrinsic parity symmetry, evolving into intricate patterns over time. This evolution is particularly susceptible to intrinsic decoherence, which significantly dampens these quantum features. Our findings show that the OTD is a powerful tool for tracking coherence loss and for accurately capturing the combined effects of nonlinearity and state symmetry on a system’s quantum state.

Intrinsic decoherence effect on dynamics of a Λ -type qutrit interacting nonlinearly with a coherent field

A.‐B. A. Mohamed, M M Elkhateeb, Mostafa Hashem +1 more

In this paper, an intrinsic decoherence model is solved analytically for a Λ-type qutrit interacting with a coherent field through intensity-dependent coupling. The effects of the qutrit-cavity interaction, the intrinsic decoherence and the initial coherent field intensity are examined on some quantum phenomena as: atom population inversion, mixedness, entanglement as well as total correlation. It is found that the increase of the physical parameters, the regular oscillatory behavior of the qutrit-population collapses and revivals are changed remarkably. The interaction between the three-level atom and the coherent cavity field generates a strong mixture, negativity entanglement and total correlation (classical + quantum). The growth, the regularity and the stability of these quantum effects depend on the decoherence and the initial coherent cavity intensity.

Optical tomography dynamics induced by qubit-resonator interaction under intrinsic decoherence

A.‐B. A. Mohamed, Hichem Eleuch

A superconducting circuit with a qubit and a resonator coupled via a two-photon interaction is considered. When the resonator is initially in a superposition of coherent states, optical tomography and quantum coherence dynamics are examined in the context of intrinsic decoherence. The results reveal that optical tomography is a good quantifier of the quantum coherence produced by the qubit-resonator interaction. The effects of qubit-resonator detuning and intrinsic decoherence on the dynamics of optical tomography distributions for coherent and even coherent states are investigated. The dynamics of optical tomography distributions are highly dependent on detuning and intrinsic decoherence. Our numerical simulations reveal that there is a relation between the optical tomography and the generated quantum coherence. When the qubit-resonator detuning and intrinsic decoherence are augmented, the amplitude and intensity, as well as the structure of the optical tomography, change substantially.

Exploring optical tomography dynamics for a dissipative coherent cavity in interaction with two-level atomic system

A.‐B. A. Mohamed, Tahani A. Alrebdi, Fatemah Homoud Alkallas +2 more

In this paper, we explore the optical tomography and quantum coherence dynamics for a coherent cavity field interacting with a two-level atom via intensity dependent coupling. We derive a specific solution to the master equation for the Jaynes–Cummings model, considering cavity damping. This solution reveals how the atom coherent-cavity interactions can produce new coherent states when the initial dissipative cavity-field state is coherent state or even coherent state. The effects of the atom-coherent-cavity interactions and the cavity damping, on the dynamics of the initial coherent state optical tomography and coherence is examined. In addition to the nonclassical properties, the atom–cavity interactions have a remarkable capacity to form distinct cavity field states linked to certain optical tomography distributions. Additionally, we investigate the maximal optical tomography dynamics for coherent state and even coherent state considering a range of cavity damping and detuning values.

Optical tomography and coherence of a cavity interacting with two time-dependent position qubits

A-B A Mohamed, Hichem Eleuch

Abstract Optical tomography is a widely used method for estimating complex information. It provides a monotonic relation between the coherent field states density and their corresponding probability distributions. This approach is critical for validating any quantum information processing system’s implementation. This paper explores the optical tomography and coherence dynamics for a cavity interacting with two two-level atoms having time-dependent locations. We analyze the dynamics of the photon-field states, as two moving atoms enter a cavity filled with two superposed coherent states. The von-Neumann entropy dynamics illustrates how interaction couplings between the two atoms and cavity can give rise to entangled states under the effects of the atom-field couplings and the time-dependent atomic location parameter. Aside from coherence, the interactions between the cavity and atoms are essential for producing nonclassical proprieties in optical tomography. Furthermore, we investigate the dynamics of optical tomography densities with respect to the couplings between atoms and photons for time-dependent atomic location. Our results show that the couplings between atoms and cavity not only accelerate but also improve the processes involved in generating nonclassical optical tomography and coherence dynamics.

Partial stability of induced entanglement in an off-resonance qutrit-cavity system with nonlinear coupling and intrinsic decoherence

Abdel‐Baset A. Mohamed, Mansour F. Yassen, H. A. Hessian

In this article, we introduce an analytical description for the nonlinear off-resonance qutrit-cavity system through intensity-dependent nonlinear coupling under intrinsic decoherence. When the cavity is initially in coherent and even coherent states. The dynamics of the negativity entanglement, in the off-resonance qutrit-cavity system, is investigated under the physical parameters of the qutrit-cavity detuning, the intrinsic decoherence as well as the initial cavity coherent states. It is found that the ability of the off-resonance qutrit-cavity interaction to generate the entanglement, depends on the physical parameters. The high nonclassicality of the even coherent state can enhance the generated entanglement and its stability. For the intrinsic decoherence, the amount and the stability of the generated qutrit-cavity entanglement can be controlled by the coherent field intensity of the initial cavity states.
