Synchronized Independent Narrow-Band Single Photons and Efficient Generation of Photonic Entanglement
Open accessAbstract
We create independent, synchronized single-photon sources with built-in quantum memory based on two remote cold atomic ensembles. The synchronized single photons are used to demonstrate efficient generation of entanglement. The resulting entangled photon pairs violate a Bell's inequality by 5 standard deviations. Our synchronized single photons with their long coherence time of 25 ns and the efficient creation of entanglement serve as an ideal building block for scalable linear optical quantum information processing.

Examples of Hong-Ou-Mandel interference include single photons from independent trapped atoms, remote cold atomic ensembles, and independent tunable quantum dots.
“Other examples include single photons from independent trapped atoms (Beugnon et al. 2006;Maunz et al. 2007), and from remote cold atomic ensembles (Yuan et al. 2007) or independent, tunable quantum dots (Patel et al. 2010).”

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.
