Abstract:

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.
