Photon-Photon Interactions via Rydberg Blockade
Open accessAbstract
We develop the theory of light propagation under the conditions of electromagnetically induced transparency in systems involving strongly interacting Rydberg states. Taking into account the quantum nature and the spatial propagation of light, we analyze interactions involving few-photon pulses. We show that this system can be used for the generation of nonclassical states of light including trains of single photons with an avoided volume between them, for implementing photon-photon gates, as well as for studying many-body phenomena with strongly correlated photons.

A closely related experiment has been explored: strong interactions between photons are obtained by coupling light to optically dressed atoms in a Rydberg-EIT configuration, and a synthetic magnetic field in a cylindrically symmetric geometry is obtained by using a twisted optical ring-cavity.
“A closely related idea has been experimentally explored in a recent experiment [152]: strong interactions between photons are obtained by coupling light to optically dressed atoms in a Rydberg-EIT configuration [31,153]; a synthetic magnetic field in a cylindrically symmetric geometry is obtained by using a twisted optical ring-cavity [154].”

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.
