摘要 在二能级原子系统里应用光子回声CRIB技术存储光量子态的过程中,最初原子谱分布这个因素不仅影响存储效率而且还影响存储时间,我们研究了两种特殊初始原子谱分布:拉普拉斯分布和高斯分布,并且分析了存储效率和存储时间的关系。 In this article we show that,for quantum memory based on the CRIB photon echo in a two-level atomi system,the initial atomic distribution affects not only the efficiency of quantum memory but also the storage time.We study two special initial atom distributions,the Gaussian distribution and the Laplace distribution,and discuss the relation between the storage efficiency and the storage time.
