摘　　要：Nonclassical states, with features impossible to be described via the 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 classical and nonclassical states has attracted a wide range of interest.
