摘要
用六量子团簇态作为量子信道,提出一个非对称双向受控远程态制备协议.在该方案中,在监察者Charlie的控制下,Alice能够为Bob远程地制备一个两粒子纠缠态;同时,Bob也能为Alice远程地制备一个任意单粒子态.该方案涉及到单粒子测量、量子受控相位门运算、Pauli算子及经典通信,对于现代光学技术而言,它们是易于物理实现.
By using a six-quantum cluster state as the quantum channel, a protocol for asymmetric bidirectional controlled remote state preparation is proposed. In the scheme, under the control of the supervisor Charlie, Alice can remotely prepare a two-qubit entangled state for Bob, at the same time, Bob can also remotely prepare an arbitrary single-qubit state for Alice. This scheme involves single particle measurements, quantum controlled phase gate operation, Pauli operators and classical communication,and they are easily realized by physics for modern optical technology.
