Quantum Secret Sharing Scheme with N-ordered Entangled Photon pairs
A new quantum secret sharing scheme is proposed,based on N-ordered entangled photon pairs.Entangled photons are used as information carrier.Alice,the private key administrator,will divide the entangled photons into two sequences.One of the sequences will be sent to one of the partners Bob directly.After the safety of the first sequence ensured,the second sequence will be encoded and sent to another partner Charlie.Bob and Charlie will make Bell-based joint measurements with what they have received respectively,thus they obtain keys that Alice released.It needs the administrator and all the partners′ collaboration to get the whole information.Relative to there-particle entangled state,this scheme adopts two bodies entanglement,and can be experimentally realized easier.It only needs linear optical elements and simple entanglement source.
