In the framework of the dissipative dynamics of coupled qubits interacting with independent reservoirs, a comparison between non-Markovian master equation techniques and an exact solution is presented here. We study various regimes in order to find the limits of validity of the Nakajima–Zwanzig and the time-convolutionless master equations in the description of theentanglement dynamics. A comparison between the performances of the concurrence and thenegativity as entanglement measures for the system under study is also presented.
