我们提出了一种利用特定的四量子比特团簇态作为量子通道来远程制备两粒子态的方案。在一般情况和某些特殊情况下都计算了关于该准备方案的成功概率。我们的结果表明，在一般情况下，这种远程态制备的概率可以达到1/4，但在一些特殊情况下，成功的概率可以提高到1/2甚至1。
We present a scheme of remote preparation of two-particle states using a particular four-qubit cluster state as the quantum channel. The probability of success regarding this preparation scheme is calculated in both general and some particular cases. Our results show that in general such remote state preparation can be realized with a probability of 1/4. But in several special cases, the probability of success can be improved to 1/2 or even 1.
