Observation of Two-Photon Speckle Patterns
Open accessAbstract
We report the observation of speckle patterns in quantum correlations within light that is scattered by a disordered medium. The random medium is illuminated with spatially entangled photon pairs, and fourth-order speckle patterns are spatially resolved by two independently scanning detectors. Spatial entanglement gives two-photon speckle a much richer structure than ordinary one-photon speckle. Our experiments demonstrate that two-photon speckle from a surface scatterer and a volume scatterer look entirely different.

Investigations of nonclassical states of light through complex media have yet to realize the full potential of quantum walks, which require the ability to prepare arbitrary input states of the walkers.
“Whereas the propagation of nonclassical states of light through such media has been explored theoretically and experimentally (23–27), these investigations have yet to realize the full potential of quantum walks, which require the ability to prepare arbitrary input states of the walkers.”

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.
