Quantum coherence and nonlocality of two qubits in the presence of a common dephasing environment
We study the coherence and quantum correlations for a system consisting of two interacting qubits under the effect of a common environment, where the system of qubits has the dephasing coupling with its surrounding. We study the dynamical behavior of the quantumness measures when the influence of th...

| description | We study the coherence and quantum correlations for a system consisting of two interacting qubits under the effect of a common environment, where the system of qubits has the dephasing coupling with its surrounding. We study the dynamical behavior of the quantumness measures when the influence of the qubits’ interaction on the dephasing is analyzed. We display the effect of the qubit–qubit interaction and qubits–environment interaction on the measures considering the case of symmetry and asymmetry interaction between the qubits and environment. Finally, we explicitly illustrate the relation between the coherence and quantum correlations and show that quantum coherence and correlations can be preserved during the dynamics. |
