Analysis of photon-atom entanglement generated by Faraday rotation in a cavity

arXiv:quant-ph/0601180 · doi:10.1103/PhysRevA.73.053808

Abstract

Faraday rotation based on AC Stark shifts is a mechanism that can entangle the polarization variables of photons and atoms. We analyze the structure of such entanglement by using the Schmidt decomposition method. The time-dependence of entanglement entropy and the effective Schmidt number are derived for Gaussian amplitudes. In particular we show how the entanglement is controlled by the initial fluctuations of atoms and photons.
