The performance of adding or subtracting photons on two‐mode squeezed thermal states
via examining the Einstein–Podolsky–Rosen (EPR) correlation, the Hillery–Zubairy (HZ) …

Various nonclassical and quantum phase properties of photon added then subtracted
displaced Fock state have been examined systematically and rigorously. Higher-order …

The impact of a noisy Gaussian channel on a wide range of non-Gaussian input states is
studied in this work. The nonclassical nature of the states, both input and output, is …

Two new photon‐modulated states are introduced by operating a more general coherent
superposition (υ a+ ra†) m on two classical states (coherent and thermal) and their …

The ability of the nonclassical states is gauged by their utility in performing various quantum
tasks. In recent times, quantification of nonclassicality has been put forward with regard to …

Corresponding to a hypergraph G with d vertices, a quantum hypergraph state is defined by
$\left\vert G\right\rangle=\frac {1}{\sqrt {{2}^{d}}}{\sum} _ {n= 0}^{{2}^{d}-1}{(-1)}^{f (n)}\left\vert …

In this paper, we investigate one-time passing of a V-type three-level atom through a single-
mode interacting field in a cavity. We extend the idea of elementary Jaynes-Cummings …

The significance of beamsplitter in experimental optical quantum information processing and
quantum technology is discussed with a focus on the role of a beamsplitter-type Hamiltonian …

Non-Gaussianity inducing operations are studied in the recent past from different
perspectives. Here, we study the role of photon addition, a non-Gaussianity inducing …

The main focus of this thesis is to study the nonclassical and phase properties of a family of
engineered quantum states, most of which show various nonclassical features. The beauty …
