超导纳米线单光子探测器（SNSPD）是时间相关单光子计数的主要探测器类型，特别是在近红外区域。当以高计数率操作时，SNSPD表现出由RF放大链的内部器件属性和特征引起的增加的定时抖动。RF脉冲高度和形状的变化导致定时测量的延迟变化。为了弥补这一点，我们展示了一种校准方法，该方法将检测事件中的延迟与脉冲之间经过的时间相关联。通过应用从校准过程中导出的校正，可以在软件中很大程度上消除高速率下抖动的增加。我们证明了我们的方法与单像素硅化钨SNSPD，并表明它降低了高计数率抖动。该技术在去除高计数率下仪器响应函数中出现的长尾时特别有效。在11.4 MCounts/s的计数率下，我们将百分之一最大水平（FW1%M）的全宽度减少了45%。因此，该方法使某些受（FW1%M）度量速率限制的量子通信协议能够以几乎两倍的速度运行。\c{opyright} 2022.

英文摘要：
Superconducting nanowire single-photon detectors (SNSPDs) are a leading detector type for time correlated single photon counting, especially in the near-infrared. When operated at high count rates, SNSPDs exhibit increased timing jitter caused by internal device properties and features of the RF amplification chain. Variations in RF pulse height and shape lead to variations in the latency of timing measurements. To compensate for this, we demonstrate a calibration method that correlates delays in detection events with the time elapsed between pulses. The increase in jitter at high rates can be largely canceled in software by applying corrections derived from the calibration process. We demonstrate our method with a single-pixel tungsten silicide SNSPD and show it decreases high count rate jitter. The technique is especially effective at removing a long tail that appears in the instrument response function at high count rates. At a count rate of 11.4 MCounts/s we reduce the full width at one percent maximum level (FW1%M) by 45%. The method therefore enables certain quantum communication protocols that are rate-limited by the (FW1%M) metric to operate almost twice as fast. \c{opyright} 2022. All rights reserved.
