论文摘要
量子断层扫描是从实验数据中获取有关量子状态的信息的重要工具。在这项研究中，我们对各种量子断层扫描方案进行了比较分析，包括基于高度对称状态向量的方案，在相互无偏的基础（MUB）和两级变换上。使用通用分布来实现量子状态断层扫描的保真度，我们估计了用于在HAAR测量中均匀分布的一组随机状态的各个维度的量子测量值的保真度和效率。
Quantum tomography is an important tool for obtaining information about the quantum state from experimental data. In this study, we conduct a comparative analysis of various quantum tomography protocols, including protocols based on highly symmetric sets of state vectors, on mutually unbiased bases (MUB), and two-level transformations. Using the universal distribution for the fidelity of quantum state tomography, we estimate the fidelity and efficiency of quantum measurements for qudits of various dimensions as applied to a set of random states uniformly distributed over the Haar measure.
