摘要：

Multipartite squeezed thermal state is proposed based on continuous variable multipartite pure entangled state. I analyze the separable condition and calculate the upper bound of the relative entropy of entanglement of tripartite squeezed thermal state. The bound is compared with the other bound which was obtained with reduced state method. (C) 2004 Elsevier B.V. All rights reserved.
