论文摘要
我们对多模式高斯近似位置测量进行了量子信息分析,这是量子光学元素的噪声同源的基础。建立了“高斯最大化器”属性,用于减少这些测量值,这些测量值为计算(包括其纠缠辅助能力)提供了明确的公式。详细讨论了一种模式的情况。
We perform a quantum information analysis for multi-mode Gaussian approximate position measurements, underlying noisy homodyning in quantum optics. The "Gaussian maximizer" property is established for the entropy reduction of these measurements which provides explicit formulas for computations including their entanglement-assisted capacity. The case of one mode is discussed in detail.
