Based on a linearly interacting spin-boson model, we show that the multi pulse application recovers the decay of concurrence when an entangled pair of spins interacts with a reservoir that has the non-Markovian nature. We present the effectiveness of multi pulse control for both the common bath case and the individual bath case.8 pages, 2 figures submitted to Special Issue in the Journal QIC (Quantum Information and Control)Quantum Physicstext
