摘要
提出了一个利用六粒子最大纠缠态作为纠缠资源的双向量子控制隐形传态方案.该理论方案中, 六粒子最大纠缠态作为量子通道来连系着合法的三方——通信双方和控制方, 通信双方既是发送方同时也是接收方.传输过程中, Alice传输一个任意单粒子态a给Bob的同时Bob也传输一个任意的单粒子态b给Alice;由控制方Charlie来控制和协助通信双方完成最终的量子态的交换;Bob先对自己手中的粒子作一个幺正操作, 用户双方再各自对自己手中的粒子执行Bell基测量, 测量完成后通过经典信道将自己的测量结果公开宣布, 用户双方根据对方所公布的测量结果做相应的幺正操作, 从而成功地实现双向量子控制隐形传态.
Abstract
A bidirectional quantum controlled teleportation scheme using the entanglement property of six-qubit maximally entangled state was presented. In the theoretical scheme, the six-qubit maximally entangled state was employed as the quantum channel linking three legitimate participants. Users were both sender and receiver. Alice transmitted an arbitrary single qubit state of qubit a to Bob and Bob transmitted an arbitrary single qubit state of qubit b to Alice via the control of the supervisor Charlie. Users carried out the Bell state measurements on their own particles and publicly announced their measurement results via a classical channel. Then they operated proper unitary transformation on their own particles, respectively. The bidirectional quantum controlled teleportation was successfully realized.
