摘要：

We investigate the entanglement evolution of two qubits interacting with a common environment through a Heisenberg XX mechanism. We reveal the possibility of realizing the phenomenon of entanglement sudden death as well as the entanglement sudden birth acting on the environment. Such analysis is of maximal interest in the light of the large applications that spin systems have in quantum information theory.
