Data underlying the publication "Satellite-assisted Entanglement Distribution with High-Dimensional Photonic Encoding"

Code and data for the results shown in the paper "Satellite-assisted Entanglement Distribution with High-Dimensional Encoding". This physics paper presents a satellite-based protocol to simultaneously distribute multiple entangled pairs between two ground stations using high-dimensional photonics in the source. By operating the SPDC source as a source of time-bin encoded photonic qudits, simultaneous distribution of multiple entangled pairs between the ground stations can be achieved at a significantly higher rate than if the SPDC sources was operated as a source of photonic qubits. We find that for achievable coherence times of several seconds and demonstrated satellite performances from the Micius satellite, the qudit operation leads to several orders of magnitude faster distribution rates than the qubit-based operation when more than one event-ready high-quality entangled pair is desired.<br>The dataset includes the Python code for the model presented in the paper, as well as the simulation data used in the figures of the manuscript.<br>Please see the README.txt file for intructions on how to reproduce the figures.

本数据集包含论文《Satellite-assisted Entanglement Distribution with High-Dimensional Encoding》（高维编码辅助卫星纠缠分发）中展示的研究结果对应的全部代码与数据。该物理学论文提出了一种基于卫星的通信协议，可通过源端的高维光子技术，在两个地面站之间同时分发多组纠缠光子对。通过将自发参量下转换（SPDC）源作为时间仓编码的光子高维量子比特（qudits）源运行，相较于将该SPDC源用作光子量子比特源的场景，可在两个地面站之间实现多组纠缠光子对的同步分发，且分发速率显著提升。研究表明，在可实现的数秒级相干时长以及“墨子号”（Micius）卫星已验证的卫星性能条件下，当需要获取至少一组具备事件触发特性的高质量纠缠光子对时，采用高维量子比特运行方案的纠缠分发速率相较于基于量子比特的运行方案，可提升数个数量级。
