Quantum Distributed Ballot Scheme Based on Greenberger–Home–Zeilinger State

Abstract

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