摘　　要：提出一个实现二粒子纠缠态及其正交态的概率克隆方案.此方案分为两个步骤,第一步通过一个四粒子簇态作为量子信道实现未知二粒子纠缠态的量子隐形传输,第二步在态的制备者的帮助下实现二粒子纠缠态及其正交态的概率克隆.We proposed a protocol for probabilistic cloning of an unknown two-particle entangled state and orthogonal complement state. This protocol had two stage. The first stage of the protocol required usual teleportation via a four-particle cluster state as a quantum channel. In the second stage, with the assistance of the state preparer, someone could produce the perfect copies and complement copies of an unknowfl two-particle entangle state.
