报告内容简介：

Quantum physics has changed the way we understand nature, and also the way we process information. Starting from the fundamental questions raised a century ago, we have now entered an era of quantum engineering. In this talk, I will introduce our recent results on quantum sensing and communication. Quantum sensing utilizes quantum effects such as coherence, squeezing and entanglement to boost measurement sensitivity. I will summarize the paradigm of distributed quantum sensing, which utilizes multi-partite entanglement to boost the measurement of an arbitrary function of local network parameters, generalizing the famous Heisenberg limit of quantum sensing; distributed quantum sensing has a wide range of applications, including dark matter search in different platforms and quantum machine learning. Then, I will briefly present our recent results on quantum radar and quantum spectroscopy.  Finally, I will introduce our works on quantum communication. Claude Shannon established the famous classical capacity of communication channels---the ultimate rate at which classical physics allows us to communicate. Quantum physics has made things more interesting. To begin with, I will introduce our recent works in breaking the Shannon capacity for the first time, by utilizing quantum entanglement; Next, I will briefly summarize works on quantum information transmission, including quantum transduction and quantum repeaters.
