Concurrence of a state as a function of the channel strength parameter p for (a) amplitude damping and (b) depolarizing channel. Here the red and blue curves correspond to the cases with local noise on qubit U and L, respectively. We have chosen \({\rho }_{11}=\mathrm{0.9,}\,{\rho }_{22}=\mathrm{0,}\,{\rho }_{33}=0.08\), and \({\rho }_{44}=0.02\).
