摘要
本文应用J-C模型研究了两个二能级原子依次穿过一个高Q光场时系统的状态波函数和密度矩阵,并计算了两个二能级原子子系统的线性熵,分析了此时两个原子的纠缠特性。
Using J - C model, this paper studied the state wave function and density matrix of system when two two - level atoms passing through a high - Q cavity field one after the other, calculated the linear entropy of the two atoms, and analyzed the entanglement properties of the two atoms in this ease.
