提出了一种仅用两组五比特GHZ态作为量子信道，控制联合远程制备任意六比特团簇态的方案。在我们的方案中，Alice首先根据所需的六量子比特团簇型态的真实的系数和复系数进行两组两量子比特的投影测量。然后，控制器Charlie必须根据Alice的测量结果应用另一个两量子比特投影测量。最后，Bob可以根据适当的幺正操作获得期望的六量子比特簇型状态。我们的方案可以达到单位成功概率。
A scheme for the controlled joint remote preparation of an arbitrary six-qubit cluster-type state by using only two sets of five-qubit GHZ states as quantum channel is proposed. In our scheme, Alice firstly performs two sets of two-qubit projective measurement according to the real coefficients and the complex coefficients of the desired six-qubit cluster-type state. Then, the controller Charlie must apply another two-qubit projective measurement according to the Alice’s measurement result. Finally, Bob can obtain the desired six-qubit cluster-type state according to an appropriate unitary operation. Our scheme can achieve unit success probability.
