Highly excited (high principle quantum number) Rydberg atoms and molecules, which are considered as a bridge between classical and quantum world due to their mesoscopic dimensions, can play a key role in quantum information processing. Although the properties of Rydberg atoms and molecules have been extensively investigated, the dynamics of Rydberg wave packets, e.g., the population and decay of autoionizing states, have not been fully understood. In the proposed work entitled "Probe and control of Rydberg wave packets in atoms and molecules", I will develop a novel pump-probe experiment by combining ultrashort laser pulses with a reaction microscope to resolve the dynamics of electronic wave packets emitted from the Rydberg atoms and molecules. In the last part of the proposed work, a new Terahertz (THz) pulse generation setup will be built, and will be used for significantly improving the pump-probe experiment as the THz pulses act on the same time scale as the Rydberg wave packet dynamics. My work will contribute to the understanding of the highly excited states of atoms and molecules, which are always produced in intense laser pulses, and have been largely ignored until recently. These insights pave the way towards new remote sensing techniques and contribute to the development of quantum control of chemical reactions. The proposed work will also have positive impact on my scientific skills in my research field and serve the goal of transferring advanced techniques to Germany. Last but not least, the new scientific achievements will contribute to the prosperous development of European Leadership in the field of strong-field laser physics.

高度激发的（高量子数）Rydberg原子和分子，由于其介观尺寸，它们被认为是经典世界和量子世界之间的桥梁，可以在量子信息处理中起关键作用。尽管已经对Rydberg原子和分子的性质进行了广泛的研究，但尚未完全了解Rydberg波数据包的动力学，例如自动取代状态的种群和衰减。在拟议的作品中，标题为“原子和分子中Rydberg波数据包的探测和控制”，我将通过将超短量激光脉冲与反应显微镜相结合，以解决从Rydberg Atoms和Molecules中产生的电子波数据包的动力学，从而开发一种新型的泵种实验。在拟议的工作的最后一部分中，将建立一个新的Terahertz（THZ）脉冲生成设置，并将用于显着改善泵浦探针实验，因为THZ脉冲与Rydberg Wave Packet Packet Dynamics相同的时间尺度起作用。我的工作将有助于理解原子和分子的高度激发态，这些态总是以强烈的激光脉冲产生，并且直到最近才被忽略。这些见解铺平了通往新的遥感技术的道路，并有助于化学反应的量子控制。拟议的工作还将对我的研究领域的科学技能产生积极影响，并为将先进技术转移到德国的目标。最后但并非最不重要的一点是，新的科学成就将有助于欧洲在强场激光物理学领域的繁荣发展。
