中文摘要： 从理论与实验两方面研究超短激光脉冲与量子相关体系的相互作用以及量子态的操控。主要研究具有量子相关(如量子纠缠)的二体二能级、二体三能级体系和多体多能级体系，研究其量子相干特性和非经典量子相关性质(如量子纠缠和量子无序等)的动力学过程，在此基础上研究如何实现量子态的操控和对所蕴含的量子信息的处理方法(如转换、存储、提取和再现等)。在理论上用光与物质相互作用的半经典理论和全量子理论，建立和发展相应的物理机制、理论模型和计算方法；在实验上用超短激光脉冲(包括整形脉冲)技术研究体系的超快动力学过程、通过调控激光参量(如相位、振幅、形状、偏振等)进行量子态的调控。通过理论和实验的研究，期望一方面可以深入理解光与量子相关体系相互作用的物理机制和特性，另一方面寻求用超短激光脉冲手段操控量子态，并通过记录和分析量子态的非经典量子相关特性以寻求实现量子信息处理的新原理与新方案。

英文摘要： We study on the interaction of quantum correlation system with ultra-short laser pulses and manipulation of quantum states, especially the two-body two-level system, two-body three-level system, many-body many-level system with quantum correlation, such as quantum entanglement, both theoretically and experimentally. We study on the dynamics process of quantum coherent characteristics and non-classical quantum correlation properties, such as quantum entanglement and quantum disorder. On this basis we research on how to realize the manipulation of quantum states and then the processing of quantum information, for example, transfer, storage, retrieval, reproduction and so on. On the one hand, based on the semi-classical theory of the interaction between light and matter as well as full quantum theory, we establish and develop related physical mechanisms, theoretical model and computing method. On the other hand, we study the ultra-fast dynamics process of the system by the use of ultra-fast laser pulses, including the shaped pulse in practical way. By means of regulating properly the parameters of laser pulses, such as phase, amplitude, shape, polarization, we can manipulate the quantum states. According to these methods and techniques above, we expect to understand the physical mechanisms and characteristics of in
