Abstract
Quantum secret sharing (QSS) is a project to distribute a secret message to multi-parties, who cannot restore it individually only need to cooperate in order to decode it. Here we design a five-partite QSS scheme to perform continuous-variable threshold quantum secret sharing. To finish the secret reconstruction for five players, we use two different methods including feedfoward loop and Mach-Zehnder interferometers. It shows that this scheme can yield perfect secret reconstruction.
