中文摘要：

我们提出了一个在三者之间利用四粒子纠缠态作为量子通道实现对任意单粒子态的信息分裂的方案。在我们的方案中,两个接收方之间有且只有在对方提供合作的情况下才能全部获得这个原始信息,而且接收方彼此之间都有同等权限去获得该原始信息,他们获得原始信息的概率是一样的,均为1。

英文摘要：

We present a quantum information splitting （QIS） protocol by using four-particle entangled states in which quantum Alice shares a secret key with three classical parties, Bob, Charlie and David.None of them can acquire the secret unless they mutuallg collaborate and each receiver has the same authority for getting the sender＇s secret. The receivers have the same probability to get the original secret and the probability is 1.
