Photon Pair Generation by Four Wave Mixing in an Atomic Ensemble

Abstract

Pump laser beam configurations for the generation of nonclassically correlated photon pairs in laser-cooled rubidium ensembles were investigated experimentally. Departing from past near-resonance single-pump configurations, we investigated both off-resonance and multifrequency pump configurations that may be capable of generating hyperentangled photon pairs that are relevant for quantum communication applications. We characterized the falloff in violation of the Cauchy-Schwartz inequality that takes place as the pump is detuned from resonance and as additional frequencies are added.
