By using quantum discord (QD), measurement induced non-locality (MIN) and negativity (QE), quantum correlation
and entanglement are investigated for two qubits in two different cases for the initial two qubitWerner states, taking into
account the influence of qubit damping. It is shown that there is no asymptotic decay for MIN while asymptotic decay
exists for QD and QE. Quantum correlations cannot be strengthened by introducing the damping. The appearance time
of stationary correlations gets shorter with the increase in the damping parameter. Finally, a uniform damping qubit can
affect the stationary correlations when the qubits are initially in an entangled state.
