摘要

单光子数技术是量子光学领域中非常重要的一种技术,已被广泛应用于双光子符合探测及关联调控实验。通过一张单光子计数卡和一台路由器,利用双光子符合探测原理,采用分时复用的方法,构建了三光子符合测量的硬件系统,并基于LabVIEW实现了三光子符合计数系统的软件控制。该系统可以实现双光子符合计数和三光子符合计数、实时显示与存储。该系统对六波混频过程产生的3束光进行三光子符合探测,获得了较好的实验结果。该系统可应用于量子通信研究领域的经典光源,也可应用于非线性过程产生的具有时间-频率量子关联特性的其他非经典光源。

Abstract

Single-photon counting is a vital technique in the field of quantum optics. It is widely used in two-photon coincidence detection and correlation control. In this study, we employ a single-photon-counting card and a router to construct a three-photon coincidence system by using two-photon coincidence and time-division multiplexing. The software control is based on LabVIEW program. The system performs coincidence detection for two or three photons, provides real-time displays, and stores the results. We obtain good results when using the system to detect three beams of light generated via the six-wave mixing process. The system can be applied to classical light sources in the field of quantum communication and to other non-classical light sources with time-frequency quantum correlations produced via nonlinear processes.
