摘要：

提出一个用GHZ态作为量子信道分离两粒子态的方案。Alice 先执行两次Ｂell基测量，Alice向她的两个接收者公布四个经典比特信息，接收者Bob 和Charlie一起合作能恢复初态。在合作中他们分别执行了单量子比特测量和幺正操作。此分离方案给出了具体的幺正操作。

Abstract:

A scheme is presented for quantum information splitting of arbitrary two-particle state by using two GHZ states as quantum channel. In this scheme, Alice performs two Bell-state measurements and publishes four classical bits to her two receivers Bob and Charlie. If the two recipients Bob and Charlie collaborate together, they can deterministically reconstruct the quantum information by performing single-qubit measurements and two single-qubit unitary operations. And the unitary operation is explicitly given with the splitting scheme.

Key words: quantum information, quantum information splitting, GHZ state, unitary operation
