Enhancing the Generated Stable Correlation in a Dissipative System of Two Coupled Qubits inside a Coherent Cavity via Their Dipole-Dipole Interplay

Research Abstract

We explore the dissipative dynamics of two coupled qubits placed inside a coherent
cavity-field under dipole-dipole interplay and 2-photon transitions. The generated non-classical
correlations (NCCs) beyond entanglement are investigated via two measures based on the
Hilbert-Schmidt norm. It is found that the robustness of the generated NCCs can be greatly enhanced
by performing the intrinsic dissipation rate, dipole-dipole interplay rate, initial coherence intensity
and the degree of the coherent state superpositions. The results show that the intrinsic decoherence
stabilize the stationarity of the non-classical correlations while the dipole interplay rate boost them.
The non-classical correlations can be frozen at their stationary correlations by increasing the intrinsic
dissipation rate. Also NCCs, can be enhanced by increasing the initial coherent intensity
