Quantitative analysis of entanglement degree under various parameters

Abstract

We classify different classes of entangled states arise in a two-qubit system. Some of these classes are of Bell's state types, while others are of the Werner's state types. The degree of entanglement is quantified for different values of the atomic and the cavity parameters. We show that it is possible to generate entangled state with high degree of entanglement by controlling the detuning and the number of photon inside the cavity.
