Abstract 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.
