Driving non-Gaussian to Gaussian states with linear optics
Open accessAbstract
We introduce a protocol that maps finite-dimensional pure input states onto approximately Gaussian states in an iterative procedure. This protocol can be used to distill highly entangled bipartite Gaussian states from a supply of weakly entangled pure Gaussian states. The entire procedure requires only the use of passive optical elements and photon detectors, which solely distinguish between the presence and absence of photons.

The main theorem cannot be applied, in a straightforward manner, to the resource theory of asymmetry because in that theory the regularized relative entropy of asymmetry is zero [28].
“Finally, our main theorem also cannot be applied, in a straightforward manner, to the resource theory of asymmetry since in that theory the regularized relative entropy of asymmetry is zero [28].”

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.
