描述了一个利用GHZ态对任意单粒子直积态进行信息分裂的方案.研究了任意单粒子直积态,在几个接收者之间相互合作的情况下,这个初始态才能被恢复,每个信息的接收者都有同等的权限去获得发送者的信息,他们获得原始信息的概率是—样的,获得a粒子信息的概率为2|βb|2,获得b粒子信息的概率为2|βa|2.

A scheme is proposed for quantum information splitting (QIS) of a product state of an arbitrary single-qubit state with three-qubit GHZ states.The scheme focuses on a product state of an arbitrary single-qubit state,and the original state can be reconstructed only if the receivers cooperate with each other.Every receiver has the same authority for getting the sender's secret,and the receivers have the same probability to get the original secret,the probability to gain |φ>a is obtained as 2|βb|2,the probability to gain |φ>b is obtained as 2|βa|2.
