Pixel Entanglement: Experimental Realization of Optically Entangledd=3andd=6Qudits
Abstract
We demonstrate a simple experimental method for creating entangled qudits. Using transverse-momentum and position entanglement of photons emitted in spontaneous parametric down-conversion, we show entanglement between discrete regions of space, i.e., pixels. We map each photon onto as many as six pixels, where each pixel represents one level of our qudit state. The method is easily generalizable to create even higher dimensional, entangled states. Thus, the realization of quantum information processing in arbitrarily high dimensions is possible, allowing for greatly increased information capacity.

High dimensional entangled qudits have been created by transverse spatial correlations of two SPDC photons, or using transverse momentum and position entanglement in pixel entanglement.
“High dimensional entangled qudits have also been created by transverse spatial correlations of two SPDC photons (Neves et al., 2005), or using transverse momentum and position entanglement of photons emitted in SPDC, in a form called pixel entanglement (O'Sullivan-Hale et al., 2005).”

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.
