提出了七粒子量子纠缠态作为量子信道的双向不对称控制通讯方案,此方案中Alice传输 任意单量子比特(或任意两量子比特)给Bob、Bob传输任意两量子比特(或任意单量子比特)给Alice, 通过监督者Charlie来控制。分别对Alice和Bob传输的最终信息进行Bell基测量,对Charlie的结果进行 冯·诺依曼测量,测量结果表明所提方案可以完美实现,为量子光学领域产生多粒子纠缠源传输通讯提 供了有效的多信息量、高安全度方法。

A bidirectional asymmetric control communication scheme in which seven-particle quantum entangled state is used as quantum channel is proposed. Alice transmits any single quantum bit (or any two quantum bits) to Bob and Bob transmits any two quantum bits (or any single quantum bit) to Alice via controlling of the supervisor Charlie. Bell base measurement is performed on final information transmitted by Alice and Bob, respectively. Von Neumann measurement is performed on Charlie’s results. The measurement results show that the proposed scheme can be realized perfectly. It provides an effective multi-information and high security method for the generation of multi-particle entanglement source transmission communication in quantum optics field.
