摘要 本文从研究初态为一般纠缠态的两个异模光子与初态为一般叠加态的二能级原子的相互作用着手,对得到的三体纠缠态的纠缠度进行了分析,并进一步讨论了系统初态为某些特殊状态时的纠缠演化。最终都得出了简明的演化公式,并且在某些特殊状态时发现系统将演化成三体GHZ态。 We study from the interaction of a two -level atoms on arbitrary state and two different - mode photons on entangled state, then make analysis of entanglement state of Three - qubit entangled State achieved, to go a step further,we study the Entanglement of some special state of the system. In the end ,we achieve some useful formula and Three -qubit GHZ State on some state initially.
