Data analysis is minimum and definite conclusions are obtained without evaluation of moments, or any other more sophisticated procedures. These nonclassical tests are very general and independent of other typical quantum signatures of nonclassical behavior such as sub-Poissonian statistics, squeezing, or oscillatory statistics, being insensitive to the nonclassical behavior displayed by other variables.engjournal articlehttp://dx.doi.org/10.1103/PhysRevA.84.042111http://journals.aps.org/open access535Quantum opticsStatesEntanglementLightTomographyCriterionAtomsNoiseLimitÓptica (Física)2209.19 Óptica Física
