报告摘要/Abstract：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 effect to attain far better precision than classical schemes. In this talk I will present a systematic way to identify the ultimate precision limit in quantum metrology and design optimal protocols to achieve it. I will also talk about the tradeoff relation among the precision limit for the estimation of multiple parameters. At the end of the talk, I will briefly mention our summer workshop for PhD applicants of 2024 (see http://hkpfs.erg.cuhk.edu.hk/for the application of the summer workshop)
