Abstract

An arrangement for producing correlated and entangled photons and atoms is proposed. A geometry known as a two-beam-excited conical emission for degenerate four-wave mixing in alkali vapours is used to create correlated photons near the resonance frequencies of Bose-condensable alkali atoms. These photons can then be allowed to interact with an atomic Bose-Einstein condensate and eject correlated and entangled atom beams. A description of the proposed source and some of the possible applications are given.
