We address the entanglement dynamics of two initially entangled non-interacting
qubits subjected to the independent sources of classical noises. As classical noises, we consider
different configurations of two important classical noises, i.e., static noise and random
telegraph noise. Previous studies have focused on the local classical noises acting in the
same directions and producing the same relaxation or dephasing dynamics on the qubits.
Here, however, we focus on the local classical noises acting in perpendicular directions and
producing pure relaxation and dephasing dynamics on the first and second qubits, respectively.
This leads to considerably different dynamics of entanglement compared to the one
of previous studies. When the qubits are both locally coupled to either the random telegraph
noises in the weak coupling regimes or the static noises, we find that there occurs only the
entanglement sudden-death effect, while for other configurations the entanglement sudden
death may be followed by the revival of entanglement.
