Nonclassical effects in phase space
Abstract
We introduce a quantitative measure of nonclassical behavior based on negative regions of quasiprobability distributions. Zeros of the antinormal ordered phase-space representation characterize a state to be maximally nonclassical with respect to this measure. All pure states of a particle or of a single field mode, except those with Gaussian quasiprobability distributions, have one or more zeros in this representation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
