摘要:
提出了一个用4粒子团簇态作为量子信道传输量子态信息以实现双向通信的方案.在该方案中,通信双方Alice和Bob事先共享一个4粒子团簇态.在通信过程中:首先,将4粒子团簇态与双方要传递的量子态信息共同构成系综态;然后,Alice和Bob分别对自己拥有的部分粒子作Bell基的联合测量,并把测量结果通过经典信道告诉对方;最后,Alice和Bob根据对方公布的测量结果,作相应的幺正变换,就可以在自己的粒子上重现对方要传送的量子态信息.这样就达到了实现量子态的双向通信的目的.
Abstract:
A scheme of using four-qubit cluster state as quantum channel(QC)to convey the quantum state information is proposed to realize two-way communication.In this scenario,two sides of communication,Alice and Bob,share a four-qubit cluster state.In the process of communication,at first,four-qubit cluster state form a whole system with quantum state information two sides have.Then,Alice and Bob perform Bell-state joint measurements to their own part qubits respectively,and tell the measured results to each other via classical channel(CC).Finally,according to the measured results,Alice and Bob make corresponding unitary transformations,hence its own party can reappear the opposite quantum state information.So two-way communication of quantum state information is achieced.
