摘　　要：研究了任意两量子位原子与Fock态光场相互作用系统中两原子间的量子纠缠和量子关联,并对共生纠缠度和几何量子失协随时间的演化进行了讨论。结果表明:光场的光子数越大,共生纠缠度和几何量子失协演化曲线周期变长,振荡频率增大。在不同的原子初态下,两原子间量子纠缠和量子关联表现出不同的演化特性。Quantum entanglement and quantum correlation in the system of an arbitrary two-qubit atoms interacting with the Fock state are investigated. Concurrence and geometrical quantum discord are proceed contrast analyze. Photon number of light field is larger,curve period,oscillation frequency increases. In the different initial state of atoms,quantum entanglement and quantum correlation of two atoms showed different evolution.
