Observation of Spatial Quantum Correlations Induced by Multiple Scattering of Nonclassical Light
Open accessAbstract
We present the experimental realization of spatial quantum correlations of photons that are induced by multiple scattering of squeezed light. The quantum correlation relates photons propagating along two different light paths through the random medium and is infinite in range. Both positive and negative spatial quantum correlations are observed when varying the quantum state incident to the multiple scattering medium, and the strength of the correlations is controlled by the number of photons. The experimental results are in excellent agreement with recent theoretical proposals by implementing the full quantum model of multiple scattering.

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.
