We discuss the application of dipole blockade techniques for the preparation of single-atom and singlephoton sources. A deterministic protocol is given for loading a single atom in an optical trap, as well as ejecting a controlled number of atoms in a desired direction. A single-photon source with an optically controlled beamlike emission pattern is described.

Colloquium: Trapping and manipulating photon states in atomic ensembles (2003, background): “Ideas for using blockade mechanisms for spin squeezing (Bouchoule and Molmer, 2002), robust generation of nontrivial atomic states (Unanyan and Fleischhauer, 2002), and single atom/photon sources (Saffman and Walker, 2002) have also been discussed recently.”
Analysis of a quantum logic device based on dipole-dipole interactions of optically trapped Rydberg atoms (2005, background): “A number of possible solutions to these questions have been discussed in the literature[23, 24, 25, 26, 27, 28, 29, 30].”
