Strong quantum correlations in four wave mixing in ${}^{85}$Rb vapor

Abstract

We study quantum intensity correlations produced using four-wave mixing in a room-temperature rubidium vapor cell. An extensive study of the effect of the various parameters allows us to observe very large amounts of non classical correlations.
