摘要
Motivated by the complementary relations of the Greenberger-Horne-Zeilinger (GHZ) entangled tripletparticlestates,a novel way of realizing quantum distributed ballot scheme is proposed.The ballot information is encodedby local operations performed on the particles of entangled GHZ triplet states,which ensures the security of the presentscheme.In order to guarantee the security of this scheme,the checking phase is designed in detail on the basis of theentangled GHZ triplet state.The analysis shows the security of the proposed scheme.
