- 适合量子网络实验与高精度时序系统
在分布式量子应用如纠缠分发中，精确的时间同步和高效的时间标记数据处理至关重要。传统系统常面临数据溢出、同步漂移和存储效率低的问题。本文提出一种模块化时间标记（TT）代理，利用白兔（White Rabbit）设备提供的1脉冲每秒（PPS）信号实现全网同步，同时结合实时校准、溢出缓解和数据压缩技术。一次跨两个实验室的实时纠缠分发实验验证了系统性能，实现了每秒25,000次的同步符合探测。
原文摘要 · Abstract (English)
In distributed quantum applications such as entanglement distribution, precise time synchronization and efficient time-tagged data handling are essential. Traditional systems often suffer from overflow, synchronization drift, and storage inefficiencies. We propose a modular Time Tagging (TT) agent that uses a 1 pulse per second (PPS) signal from White Rabbit (WR) devices to achieve network-wide synchronization, while applying real-time calibration, overflow mitigation, and compression. A live two-lab entanglement distribution experiment validated the system's performance, achieving synchronized coincidence detection at 25,000 counts/sec.
