摘要/Abstract

摘要： 提出了一种可控量子隐形传态与远程制备相结合的新方案，结合了两种量子信息通信方式。在所提出方案中，Alice和Bob既是发送者又是接收者，Alice、Bob 和 Charlie共享一个九比特量子纠缠态作为量子信道。在Charlie的控制下，通过一系列投影测量操作，Alice可以传送一个未知的任意单比特量子态给Bob，与此同时，Bob还可以远程制备任意已知的两比特量子态给Alice。与其他此类型的混合方案相比，所提方案中远程制备的量子态从单比特提升为两比特，分析与推理表明所提出方案的成功率为100%。

Abstract: A new scheme combining controllable quantum teleportation with remote state preparation to realize two kinds of quantum information communications simultaneously is proposed. In the proposed scheme, Alice and Bob are both senders and receivers, and Alice, Bob and Charlie share a nine-qubit entangled state as quantum channel. Under the control of Charlie, Alice can transmit an unknown arbitrary single qubit state to Bob through a series of projection measurement, and meanwhile, Bob can also remotely prepare an arbitrary known two-qubit state to Alice. Compared with other similar hybrid schemes, the state of remote preparation in the proposed scheme is improved from single qubit to two-qubit. Analysis and inference show that the success rate of the proposed scheme is 100%.

Key words: quantum optics；quantum teleportation, remote state preparation;projection measurement, nine-qubit entangled state
