主　　题：entanglement swapping quantum Fourier transform quantum secret sharing 

摘      要：A quantum secret sharing （QSS） protocol between multiparty and multiparty is proposed, based on Greenberger-Horne- Zeilinger （GHZ） state. The protocol utilizes quantum Fourier transform and entanglement swapping to achieve a high intrinsic efficiency and source capacity. Then, the security of this protocol against some possible eavesdropping strategies has been analyzed. Furthermore, the presented protocol is generalized to the d-level case.
