用GHZ态实现任意两粒子态的量子信息分离方案(英文)

Quantum information splitting of arbitrary two-particle state using two GHZ states

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.
