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 h ighestachievable precision with given resources and design schemes a tttoain it. With recent development of technology, it is now possible to design protocols utilizing quantum mechanical effe ctot attain far better precision than classical schemes. In this t aIl kwill present a systematic way to identi fythe ultimate precision limit in quantum metrolog yand design optimal protocols to achieve .i t I wil lalso talk about the tradeoff relation among the precision limit for the estimation of multiple paramet ers.
