| 摘 要： | 本文提出一个用腔QED技术实现的混态纠缠交换方案。混态是一个混合的贝尔态，这在量子信息过程中比纯态作为量子通道更具有实际意义。我们（L2，z，L3,z）从噪声Lindblad主方程出发，给出了在腔QED系统密度矩阵解析表达式，讨论了纠缠交换的保真度和概率。

| Abstract: | We propose an entanglement swapping scheme in cavity QED via mixed states.In this paper,the mixed state is a mixed Bell-state,which is more practical than pure one as quantum channel in quantum information processing.We solve analytically a master equation in the Lindblad form with(L2,z,L3,z)-type of noise in cavity QED.The fidelity and probability of these protocols are discussed. |
