摘　　要：We investigate entanglement dynamics of three independent qubits each locally interacting with a zero-temperature non-Markovian reservoir.The effects of environment's amount of non-Markovianity or parameters in initialstates on the three-qubit entanglement dynamics are presented in detail.It is found that the entanglement of such asystem revives after a finite dark period when a proper degree of non-Markovian is present.A deep comparison to thatin two-qubit system is also made.
