摘　　要：We demonstrate that the multipartite Bell-inequality violations can be fully destroyed in a finite time in three- qubit systems under decoherence induced by stochastic dephasing. It is significant that the study of tripartite systems can show fundamental characteristics which do not exist in bipartite systems.We demonstrate that the multipartite Bell-inequality violations can be fully destroyed in a finite time in three- qubit systems under decoherence induced by stochastic dephasing.
