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,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.
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 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.
