Abstract: A new application of a genuinely six-qubit entangled state is studied for bidirectional quantum controlled remote state preparation. In the protocol, two distant parties can simultaneously and deterministically exchange their states under of a third remote parties in such a way that it cannot succeed without permission of the controller. A genuinely six-qubit entangled state as the original non-local quantum resource is priori shared among the parties.

Key words: bidirectional remote state preparation, genuinely six-qubit entangled state, adapitive measurements

摘要： 研究了真六量子比特纠缠态在双向量子受控远程态制备中的一个新应用。在协议中，远程的两方在遥远的第三方控制下，能够同时地、确定地交换他们的量子态。如果没有控制者的允许，这种交换是不能成功的，而作为原始的非局域量子资源的一个真六量子比特纠缠态是预先被三方共享的。
