摘要：

We　study　a　dynamic　process　of　disentanglement　by　considering　the　time　evolution　of　bound　entanglement　for　a　quantum　open　system,　two　qutrits　coupling　to　a　common　environment.　Here,　the　initial　quantum　correlations　of　the　two　qutrits　are　characterized　by　the　bound　entanglement.　Both　bosonic　and　spin　environments　are　considered.　We　found　that　the　bound　entanglement　displays　collapses　and　revivals,　and　it　can　be　stable　against　small　temperature　and　time　change.　The　thermal　fluctuation　effects　on　bound　entanglement　are　also　considered.　©　2007　EDP　Sciences/Società　Italiana　di　Fisica/Springer-Verlag.
