SNSPD arrival-time histograms given varying incident mean photon numbers

The data set consists of arrival-time histograms from a trigger signal (fast photodiode, Thorlabs) to the rising edge of an SNSPD (Single Quantum) trace and was originally recorded in the form of raw time tags with a Time Tagger X (Swabian Instruments).In total 122 different coherent states were recorded (with 570000 samples each). The incident mean photon numbers per pulse scale linearly from 0 to 16 in steps of 1, quadratically from 25 to 10000 and then exponentially to approximately 68000. The histogramx-axis has units of picoseconds (from 0ps to 549ps in steps of 1ps).本数据集包含触发信号（快速光电二极管，Thorlabs）对应超导纳米线单光子探测器（SNSPD，Single Quantum）轨迹上升沿的到达时间直方图，原始数据通过Swabian Instruments公司的Time Tagger X设备以原始时间标签格式录制。本次数据集共采集了122种不同的相干态（coherent states），每种相干态对应570000个采样样本。各脉冲的入射平均光子数变化规律为：以步长1从0线性增长至16，随后以二次方规律从25增长至10000，最终以指数规律增长至约68000。该直方图的横轴单位为皮秒（ps），取值范围为0ps至549ps，步长为1ps。
