Data and software supporting the publication: Metropolitan-scale heralded entanglement of solid-state qubits

Please read the README.txt for latest information and installation instructions. This repository contains the data and code to plot the figures of themanuscript called "Metropolitan-scale heralded entanglement of solid-state qubits". The data contains:Timing, phase and polarization stability data of the metropolitan linkCorrelations of qubit state outcomes upon measuring of a photon for different readout bases and the calculation of resulting correlators <ZZ>, <XX> and <YY> and the entangled state fidelity. Both in the post-process and heralded situation.Entangled state fidelity as function of photon acceptance window length, including the expected fidelity generated from a monte-carlo simulation. Both in the post-process and heralded situation.Echo contrast from both qubits used Every folder contains the data pertaining to the name of the folder.Some are grouped due to their plot being in the main text as well ascorresponding (raw, sweep, etc.) data in the supplementary materials.Every figure set has a self-contained jupyter notebook, that in combination with the data,will generate all the figures in line and save the output in './output' as pdf. Figures related to the supplementary materials are preceded by 'S'.

请查阅README.txt文件以获取最新信息与安装指南。本仓库包含用于绘制题为《Metropolitan-scale heralded entanglement of solid-state qubits》的学术论文所需的全部数据与绘图代码。本数据集包含以下内容：
1. 都市链路的时序、相位与偏振稳定性数据；
2. 针对不同读出基测量光子时得到的量子比特态结果相关性，以及由此计算得到的<ZZ>、<XX>、<YY>关联函数与纠缠态保真度，涵盖后处理与预告式两种场景；
3. 以光子接收窗长度为自变量的纠缠态保真度数据，包含蒙特卡洛（Monte Carlo）模拟得到的理论预期保真度，同样覆盖后处理与预告式两种场景；
4. 所用两个量子比特的回波对比度数据。

每个文件夹均包含与文件夹名称对应的专属数据。部分数据会被归类整合，因其绘图既见于论文正文，其原始、扫描等对应数据也收录于补充材料。

每一组绘图均配有独立的Jupyter Notebook，结合对应数据即可完整复现全部论文图表，并将生成的PDF格式图片保存至'./output'目录。与补充材料相关的图表文件名均以'S'作为前缀。
