在分布式量子应用中,例如纠缠分布、精确的时间同步和高效的时间标记数据处理至关重要。 传统系统经常受到溢出、同步漂移和存储效率低下的影响。 我们提出了一个模块化的时间标记(TT)代理,它使用来自白兔(WR)设备的每秒1脉冲(PPS)信号来实现网络范围的同步,同时应用实时校准,溢出缓解和压缩。 一个实时的双实验室纠缠分布实验验证了系统的性能,实现了25,000计数/秒的同步巧合检测。
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.
