自「電磁波引發透明」的發現以來，光速減慢與與光儲存取出變成為此現象的有趣課題。2005年十一月《自然》雜誌中連續發表了電磁波引發透明現象藉以儲存單光子的實驗，前述實驗更驗證了存入與取出之光子有高度的關聯性，意即此存入與取出並不會改變光子的統計特性；便能將依量子狀態非藉由量測而儲存的古典機制，而直接的把量子狀態的波函數存入介質中。此一特性在人類長久以來對於量子電腦記憶元件的實現跨上一大步，使得量子電腦有了緩衝媒介，並藉光子開關﹝Photon Switching﹞、Cross Phase Modulation操控，達到量子狀態的操控，有如傳統電腦中電晶體來作為狀態的操控，組合出所需要的各式運算結構。

在單光子光源實現之前，首先考慮到當光源出現後實驗操控的需求，必須率先建立單光子在介質中儲存取出的控制與量測能力，為後期的實驗鋪路。吾人以傳統半導體雷射光源衰弱至數個光子的脈衝強度，作為探測光束，並將其存入銣87原子低溫原子團，約略一個微秒時間，並取出觀察其行為與特性。光脈衝偵測部分以單光子模組偵測器﹝SPCM﹞檢視取出的光脈衝，發現儲存取出的機率分布與探測光束較強時以光偵測器﹝Photon Detector﹞測量的強度分布相同，與電子繞射的概念相同，並比較存入與取出的光子統計特性。藉此培養低光強實驗技術與分析技巧，將實驗室磁光陷阱系統修改成為低光強實驗的可行系統，使實驗控制與數據處理成為標準實驗程序，提供下一階段條件性單光子光源實驗的平台
