爱丽丝、鲍勃和查理是三个相距遥远的团体。Alice和Bob共享关于秘密量子比特状态的经典知识。我们考虑以下问题:“Alice和Bob如何共同为Charlie准备量子比特状态?”针对这种联合远程状态准备,提出了两种不同的协议。第一种协议使用单个GHZ状态,第二种协议使用一对EPR状态作为量子信道,其纠缠不一定是最大的。
Alice, Bob and Charlie are three remote parties. Alice and Bob share the classical knowledge of a secret qubit state. We consider the following question: ‘how can Alice and Bob jointly prepare the qubit state for Charlie?’ Two different protocols are proposed for such a joint remote state preparation. The first protocol uses a single GHZ state while the second one uses a pair of EPR states as the quantum channel whose entanglement is not necessarily maximal.
