    "abstract": "Practically applicable criteria for the nonclassicality of quantum states are\nformulated in terms of different types of moments. For this purpose the moments\nof the creation and annihilation operators, of two quadratures, and of a\nquadrature and the photon number operator turn out to be useful. It is shown\nthat all the required moments can be determined by homodyne correlation\nmeasurements. An example of a nonclassical effect that is easily characterized\nby our methods is amplitude-squared squeezing.",
