我们提出了利用四粒子态传送三粒子W态的两种方案。我们认为量子通道是一个最大纠缠态（四粒子簇态）或一个非最大纠缠态。在我们的方案中，为了实现三粒子W态的完美或概率隐形传态，需要引入额外的粒子并构造幺正变换。为了成功传输目标状态，Alice首先对初始状态执行两次controlled-NOT。两种方案的成功概率分别为1和4α2。与之前提出的方案相比，我们的方案具有更高的效率。
We present two schemes for teleporting a three-particle W state by using four-particle state. We consider that the quantum channel is a maximally entangled state (four-particle cluster state) or a non-maximally entangled state. In our schemes, it is necessary to introduce additional particle and construct unitary transformation for realize perfect or probabilistic teleportation of the three-particle W state. In order to transmit target state successfully, Alice firstly performs two controlled-NOT on the initial state. The success probabilities of our two schemes are 1 and 4α2, respectively. Compared with other schemes proposed before, our scheme has higher efficiency.
