论文摘要
已经表明,两个纠缠纯净的状态可以违反纠缠交换网络中的双尾部不平等,反之亦然。混合国家会发生什么?是否有可分离的混合状态违反了双尾部不平等?在这项工作中,我们致力于找到混合的Werner状态,这些状态通过粒子群优化(PSO)算法违反了双尾部不平等。最后,我们表明有许多国家可以分离,另一个是纠缠的,可能会违反双尾部不平等。
It has been showed that two entangle pure states can violate the bilocal inequality in the entanglement-swapping network, vice versa. What happens for mixed states? Whether or not are there separable mixed states violating the bilocal inequality? In the work, we devote to finding the mixed Werner states which violate the bilocal inequality by Particle Swarm Optimization (PSO) algorithms. Finally, we shows that there are pairs of states, where one is separable and the other is entangled, can violate the bilocal inequality.
