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 initial states on the three-qubit entanglement dynamics are presented in detail. It is found that the entanglement of such a system revives after a finite dark period when a proper degree of non-Markovian is present. A deep comparison to that in two-qubit system is also made.
