Concentration of Higher Dimensional Entanglement: Qutrits of Photon Orbital Angular Momentum
Abstract
Enhancement of entanglement is necessary for most quantum communication protocols many of which are defined in Hilbert spaces larger than 2. In this work we present the experimental realization of entanglement concentration of orbital angular momentum entangled photons. We investigate the specific case of three dimensions and the possibility of generating different entangled states out of an initial state. The results presented here are of importance for pure states as well as for mixed states.

Orbital angular momentum eigenstates of photons are states of the electromagnetic field with phase singularities and can be utilized for observation of higher dimensional entanglement.
“Orbital angular momentum eigenstates of photons are states of the electromagnetic field with phase singularities.They can be utilized for observation of higher dimensional entanglement (Mair et al., 2001;Vaziri et al., 2002Vaziri et al., , 2003)).”

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.
