Quantum noise in the parametric oscillator: From squeezed states to coherent-state superpositions
Abstract
We compare the nonclassical states of light produced by a parametric oscillator for quantum noise of different strengths. Increasing noise strength brings a transition from a slightly perturbed classical state showing squeezing to a superposition of coherent states. We use the positive-P representation to illustrate the roles of quantum noise, quantum coherence, nonlinearity, and dissipation in this simple quantum dynamical system.

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.
