标题：Quantification of optical nonclassicality: A phase-space method

作者：费少明 教授

简介：Nonclassical states, with features impossible to be described via classical theory, are important resources for many quantum technologies. For example, nonclassical optical states play a pivotal role in the development of quantum metrology both theoretically and experimentally. Thus certifying the boundary between the classical and nonclassical states has attracted a wide range of research interest.
