Abstract

We introduce semidefinite programming hierarchies for benchmarking relevant entanglement properties in the high-dimensional steering scenario. Firstly, we provide a general method for detecting the entanglement dimensionality through certification of the Schmidt number. Its key feature is that the computational cost is independent of the Schmidt number under consideration. Secondly, we provide a method to estimate the fidelity of the source with any maximally entangled state. Using only basic computational means, we demonstrate the usefulness of these methods, which can be directly used to analyze experiments on high-dimensional systems.

驾驶场景中高维纠缠的半定松弛
我们引入了半确定规划层次结构来对高维转向场景中的相关纠缠特性进行基准测试。首先,我们提供了一种通过施密特数认证来检测纠缠维数的通用方法。其主要特点是计算成本与所考虑的施密特数无关。其次,我们提供了一种估计任意最大纠缠态源保真度的方法。仅使用基本的计算手段,我们就证明了这些方法的实用性,它们可以直接用于分析高维系统的实验。2025年由美国物理学会出版
