Quantum Discord of $f$-Deformed Bipartite Entangled Oscillators

TL;DR

This paper explores quantum correlations, specifically entanglement and discord, in bipartite $f$-deformed oscillator systems, analyzing how these quantum properties depend on deformation and mixedness parameters.

Contribution

It introduces a method to construct bipartite pure and mixed states using $f$-deformed oscillators and studies their quantum correlations.

Findings

Quantum discord varies with deformation parameters.

Entanglement depends on the mixedness of states.

Deformation influences quantum correlation measures.

Abstract

Quantum correlations in compound systems are of great importance, and they are fundamental resource for the development of quantum computation protocols and quantum information. In this work we construct bipartite pure coherent states using the $f$-deformed oscillator formalism and the Barut-Girardello deformation function. Also we construct the extension of these systems to mixed states using Werner like states. For the states constructed, we study the dependence of the entanglement and quantum discord upon the deformation and mixed parameters.
