Abstract
In this project, we present a novel approach to calculate and engineer the photon correlations emerging from the interference between an input field and the field scattered by an atom in free space. Historically, it has been difficult to observe robust quantum correlations in the total field, as the inefficient atom-light coupling in free space usually causes the scattered field to be small in comparison to the input. To overcome this issue, we propose the use of separate pump and probe beams, where the former effectively enhances the atomic emission to be comparable to the probe. Additionally, we elucidate the physical origin of the non-classical correlations predicted, by studying the transient atomic state after the measurement of a photon.
