| 摘 要： | 基于多波混频参数相互作用,研究了一个五能级原子系综中的三体连续变量纠缠.其中,两个光场通过一个双通道Raman跃迁,以和模的形式组合成一个联合模与原子相互作用,这个联合模因外加相干场与第三个腔场介于混频参数相互作用,导致了3个腔场正交算符的方差和满足三体连续变量纠缠有效判据,从而实现了稳态三体连续变量纠缠.

| Abstract: | Investigates tripartite continuous variable entanglement based on multi-wave mixing in a five-level atomic system.Two of three cavity fields mediate into a pair of Raman transitions,which corresponds to the interaction of one combination mode with atoms.The coupled combination mode and the third mode are pulled into quantum correlation due to the external coherent field.The sum of variances of three cavity fields satisfies the tripartite continuous variable sufficient criterion,indicating that the tripatite continuous variable entanglement is achieved at the steady state. |
