Abstract

Joint atom-photon states can become nonseparably entangled by momentum conservation in scattering events. The consequences are open for observation in interference experiments in which one particle is used to monitor the evolution of the other. We have previously quantified the degree of available recoil entanglement in spontaneous emission, and present here the extensions to Rayleigh scattering and Raman scattering, with an emphasis on the similarity among the three cases. It is found that such scattering processes have the potential to create a higher degree of entanglement between the scattered photon and the recoiled atom than any reported to date.
