报告内容简介：
Measurement and estimation of parameters are essential for science and engineering, where the main quest is to and out the highest achievable precision with given resources and design schemes to attain it. With recent development of technology, it is now possible to design protocols utilizing quantum mechanical effects, such as superposition and entanglement, to attain far better precision than classical schemes. In this talk I will present a systematic way to identify the precision limit in quantum metrology. I will also talk about how to further improve the precision with optimal quantum controls.
