Pritchard, J. D. and Adams, C. S. and Molmer, K. (2012) 'Correlated photon emission from multiatom Rydberg dark states.', Physical review letters., 108 (4). 043601.
We consider three-level atoms driven by two resonant light fields in a ladder scheme where the upper level is a highly excited Rydberg state. We show that the dipole-dipole interactions between Rydberg excited atoms prevents the formation of single particle dark states and leads to strongly correlated photon pairs from atoms separated by distances large compared to the emission wavelength. For a pair of atoms, this enables realization of an efficient photon-pair source with on average one pair every 30 μs.
