摘要:
提出了1个以6粒子团簇态为量子信道实现2粒子未知态的受控分级量子通信方案。不同的接收者因其受发送者的信任程度不同而对未知态的恢复能力也不同。发送者对手中的3个粒子做1次 von-Neumann 联合测量，控制者根据不同的接收者或自己做局域测量或联合测量。接收者收到2次测量结果后做相应的幺正操作可恢复未知态，完成本次的量子通信。
Abstract:
A scheme of controlled hierarchical quantum information of an unknown two-qubit entangled state by u-sing a six-qubit cluster state as the quantum channel is proposed. Because of their different level of trust by the sender,different receivers have different ability to recover the unknown state. The sender needs to perform a joint von-Neumann measurement on her three qubits,controller according to different receivers take a local measurement or a join measurement. After received the two measurements,the receiver can reconstruct the unknown state by per-forming appropriate unitary operations,then this controlled hierarchical quantum communication is accomplished.
