内容摘要Abstract:

A pivotal task in science and technology is to identify the highest achievable precision in measuring and estimating parameters of interest and design schemes to reach it. The ultimate limit is not only constrained by the resource but also by the fundamental law of nature, which, up to date, is most accurately captured by quantum mechanics. With many unintuitive non-classical features, quantum mechanics also offers many possibilities to go beyond the classical limit. With recent development of technology, it is now possible to design measurement protocols utilizing quantum mechanical effects, such as entanglement, to attain far better precision than the classical schemes. In this talk I will present a general framework for quantum metrology that can identify the ultimate precision limit. Optimally controlled schemes that can attain the ultimate limit will also be presented, which is shown to outperform the existing schemes.
