论文摘要
增强量子纠缠对于许多量子信息处理应用非常重要。在本文中,我们考虑了一种基于光子减法,光子催化和添加光子的两种模式挤压真空状态(TMSV)的纠缠方案。这种操作的核心是将数字状态与每种TMSV模式混合和检测数量状态的任务。我们分析了各种设置,并找到了改善国家纠缠的最佳设置。
Enhancing quantum entanglement is important for many quantum information processing applications. In this paper, we consider a protocol for entanglement enhancing in a two-mode squeezed vacuum state (TMSVS), attained based on photon subtraction, photon catalysis, and photon addition. Central to such an operation is the task of mixing and detecting number states with each mode of TMSVS. We analyze various settings and find an optimal setup for improving the entanglement of the state.
