通过介绍六粒子纠缠态的新应用研究，提出了一个二粒子任意态的信息分离方案.在这个方案中，发送者Alice、控制者Charlie和接受者Bob共享一个六粒子纠缠态，发送者先执行两次Bell基测量;然后控制者执行一次Bell基测量;最后接受者根据发送者和控制者的测量结果，对自己拥有的粒子做适当的幺正变换，从而能够重建要发送的二粒子任意态.这个信息分离方案是决定性的，即成功概率为100%.与使用相同的量子信道进行二粒子任意态的信息分离方案相比，本文提出的方案只需要进行Bell基测量而不需要执行多粒子的联合测量，从而使得这个方案更简单、更容易，并且在目前的实验室技术条件下是能够实现的.

Through introducing the new application of a genuinely entangled six-qubit state, quantum information splitting of an arbitrary two-qubit state was investigated. For the quantum information splitting, a genuinely entangled six-qubit state was shared by a sender (Alice), a controller (Charlie) and a receiver (Bob). The sender firstly performed twice Bell-state measurements, and then the controller made a Bell-state measurement. Finally the receiver can reconstruct the arbitrary two-qubit state by performing some appropriate unitary transformations on his qubits after he knew the measured results of both the sender and the controller. This quantum information splitting scheme is deterministic, i.e. the probability of success is 100%. In comparison with the quantum information splitting scheme using the same quantum channel the sender and the controller only need to perform Bell-state measurements, not joint multi-qubit measurement, which makes this scheme simpler and easier, and can be fulfilled based on present experimental technology.
