摘要:
以6粒子纠缠态为量子信道,提出了一个单粒子未知态的量子信息共享方案.首先信息发送者对手中的粒子进行 Bell 基测量和单粒子测量,接着合法双方的任意一方对自己拥有的粒子做一次单粒子测量,则另一方对自己拥有的粒子进行适当的幺正变换,就可以重建原始粒子态,从而实现了量子信息共享.该方案成功的概率为100；
Abstract:
A scheme for quantum state sharing of an arbitrary single qubit state by using a genuinely entangled six-qubit state as a quantum channel is proposed. Firstly, the sender performs the Bell-state measurement and single qubit measurements on her qubits, respectively. Then any one of the two legitimate agents make a single qubit measurement on his qubit, and the other one(receiver) can reconstruct the original arbitrary single qubit state by performing appropriate unitary operation on his particle. The successful probability of this scheme is 100%.
