Entanglement Evolution of Two-Qubit States in the Presence of Local Decoherence

Using the factorization Law for entanglement decay derived by Konrad, T., et al.: Nature Phys. 4, 99 (2008), we investigate the one-side and two-side local decoherence effect on the dynamics of the two-qubit entangled states. Under the depolarizing channel and GAD channel with the nonzero temperature, we have found that any two-qubit states will experience ESD. Furthermore, we also investigate the entanglement dynamics under the non-Markovian case.
