论文摘要
我们为从高斯量子状态下给定的测量值获得的相关性提供了一个简单的足够标准。该标准是基于局部隐藏可变量模型的构建，该模型通过将国家固有的高斯噪声的一部分传递到测量中。我们在两种模式挤压状态下的位移光电检测设置中说明了我们的结果。在这里，我们的标准显示了在状态仍然纠缠的一系列参数的局部隐藏可变性模型的存在。
We derive a simple sufficient criterion for the locality of correlations obtained from given measurements on a Gaussian quantum state. The criterion is based on the construction of a local-hidden-variable model which works by passing part of the inherent Gaussian noise of the state onto the measurements. We illustrate our result in the setting of displaced photodetection on a two-mode squeezed state. Here, our criterion exhibits the existence of a local-hidden-variable model for a range of parameters where the state is still entangled.
