我们在场分享的一个遥远的三聚会的量状态(QSTS ) 有三原子的 GreenbergerHorneZeilinger (GHZ ) 状态的计划由洞证完和飞的 qubits 帮助了。为处于一个 GHZ 状态与三原子的系统安全地建立量隧道充当飞的 qubits 利用一些光子,它也许仅仅基于原子系统使这个遥远的 QSTS 计划比一些另外的计划更实际或光子微弱地与他们的环境交往的离子陷井系统。在洞的静止原子 qubits 的连贯在 QSTS 为聚会提供便利检查偷听,与纠缠的光子系统不同。而且,处于一个集体噪音的条件和它的现在的计划工作可能是比在在未来的应用的其它更实际的。
We present a remote three-party quantum state sharing (QSTS) scheme with three-atom Greenberger- Horne-Zeilinger (GHZ) states assisted by cavity QED and flying qubits. It exploits some photons to act as the flying qubits for setting up the quantum channel securely with three-atom systems in a GHZ state, which maybe make this remote QSTS scheme more practical than some other schemes based on atom systems only or ion-trap systems as photons interact with their environments weakly. The coherence of the stationary atom qubits in cavities provides the convenience for the parties in QSTS to check eavesdropping, different from entangled photon systems. Moreover, the present scheme works in a collective-noise condition and it may be more practical than others in applications in future.
