摘要
在共振QED腔中,设计了一个传输N个量子比特GHZ态的方案。通过选择合适的哈密顿量,无需Bell基测量,就可以实现从原子A到原子B的量子隐形传态。当然,在传输过程中要求的是选择好腔与原子的作用时间。
We design a scheme to transfer N-qubit GHZ state in cavity quantum electrodynamics (QED). By selecting the right Hamiltonian, without Bell-state measurement, the N-qubit GHZ state can be teleported from atom A to atom B. Of course, the demand is that we should choose the fight time between the cavity and the atom in the process of transmission.
