摘　　要：门光子计数器是量子光学实验中单光子探测常用的数据采集设备,用于收集单光子探测器探测到的单个光子信号。由于不同的场合需要用到不同的计数模式,商用的计数器往往难以满足具体的需求,或者造成采集效率低下。系统采用的是一种基于MicroBlaze系统FSL总线的可扩展计数器设计架构,该架构能够灵活的添加不同的计数功能,并通过统一的FSL总线和Microblaze CPU与PC通信。在该架构的基础上实现了针对量子单自旋调控实验中常用的计数模式。系统所采用的设计和实现方式可以推广到其他光子计数需求中,并具有较低的设计和生产成本。Photon counter is a common-used data collection device for single photon detection in the field of quantum optics experiment,it is used to collect single photon signal detected by single photon detector.In these realizations,a TTL counter is needed after the Single Photon Detector which generates a TTL pulse when a photon is detected.The detector is almost straightforward while the counter is various due to the different needs everywhere.The system uses a flexible and scalable architecture on the Microblaze platform to design a counter which could append new functions.In this way,we design and implement a gated counter to detect the photons in the experiments of quantum controlling over single electron spins,such as quantum dots or diamond color centers.A practical way to design different counters among different usages and needs are used by the system.
