PROJECT TITLE :

Enhanced multiparty quantum secret sharing of classical messages by using entanglement swapping

ABSTRACT :

Based mostly on the multiparty quantum secret sharing (QSS) protocol called Zhang-Man protocol, the authors proposed two schemes to reinforce the transmission potency of whole protocol. Within the proposed improved protocol, the dealer will transmit double amount of secret messages at a time securely rather than doing the first Zhang-Man protocol twice. Besides, the authors save a ton of price of whole QSS system. When the amount of secret messages is giant and the number of agents is a lot of, the performance of our protocol is much better than the Zhang-Man protocol. The authors also proposed a reuse theme, after the secret message had been deduced, the left qubits can be reused for a replacement round. All of the theme the authors mentioned above might be extended to multiparty cases in follow.
