摘要

随着量子信息领域的迅猛发展，通过实时调控量子系统的状态来控制量子态的相干与演化成为一个迫切需要解决的问题.本文研究动态双洛伦兹库对激发态原子布局数的调控，利用环境库的变化对原子系统相干性演化进行调制.讨论双洛伦兹库环境中心频率不同的动态调制形式对原子布局数演化的影响，选取双洛伦兹库环境中心频率的调制形式分别为：单次矩形脉冲、周期矩形脉冲、组合矩形脉冲和阶梯型矩形脉冲.双洛伦兹环境库的中心频率受到不同的动态环境库调制，系统的相干性演化在外力影响下得到了高效的保护和操纵，都能较好的实现可操控的量子态的相干性演化.这些为量子器件的研制提供重要的理论依据.

Abstract

This paper uses the change of environment library to modulate the coherence evolution of atomic system. The influence of different dynamic modulation forms on the evolution of atomic population is discussed. The modulation forms of the environment center frequency of double Lorentzian reservior are selected as single rectangular pulse

periodic rectangular pulse

combined rectangular pulse and step rectangular pulse. The central frequency of the double Lorentzian environment reservior is modulated by different dynamic environment reserviors

and the coherent evolution of the system is effectively protected and manipulated under the influence of external forces

and the coherence evolution of the controllable quantum state can be better realized. These provide important theoretical basis for the development of quantum devices.
