| Abstract: | Inspired by the protocol presented by Bagherinezhad and Karimipour [Phys. Rev. A 67 (2003) 044302], which will be shown to be insecure, we present a multipartite quantum secret sharing protocol using reusable Greenberger-Horne-Zeilinger (GHZ) states. This protocol is robust against eavesdropping and could be used for the circumstance of many parties. |
