The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

The exciting new features of entanglement are burgeoning with revolutionary new advances
in the areas of quantum communication, quantum information processing and quantum …

In this work, we revisit the algorithm proposed in [Results in Physics 15 (2019) 102549] for
solving an extended variant of the Deutsch-Jozsa problem. This algorithm classifies an …

Trapped and laser-cooled ions are increasingly used for a variety of modern high-precision
experiments, frequency standard applications and quantum information processing …

In this article a treatment of a three-level atom interacting with two modes of light in a cavity
with arbitrary forms of nonlinearities of both the fields and the intensity-dependent atom-field …

We present an analytical solution for a quantum system characterized by a double Λ five-
level atom interacting with an intensity-dependent coupling regime, influenced by a …

In this paper, we investigate the possibility of entanglement swap** between two
independent nonperfect cavities consisting of an atom with finite lifetime of atomic levels (as …

We propose a general formalism of a nonlinear Jaynes–Cummings-model by including
possible forms of nonlinearities of both the field and the intensity-dependent atom-field …

In this paper, we use the quantum field entropy to measure the degree of entanglement in
the time development of a three-level atom interacting with two-mode fields including all …

We investigate a modified model of the Jaynes–Cummings model involving multimode and
multiphoton processes. The interaction part of the Hamiltonian consists of a two-level atom …
