Gaussian-state entanglement in a quantum beat laser

Author(s): Tahira, R (Tahira, Rabia); Ikram, M (Ikram, Manzoor); Nha, H (Nha, Hyunchul); Zubairy, MS (Zubairy, M. Suhail)

Recently quantum beat lasers have been considered as a source of entangled radiation [ S. Qamar, F. Ghafoor, M. Hillery and M. S. Zubairy Phys. Rev. A 77062308 (2008)]. We investigate and quantify the entanglement of this system when the initial cavity modes are prepared in a Gaussian two-mode state, one being a nonclassical state and the other a thermal state. It is investigated how the output entanglement varies with the nonclassicality of the input Gaussian state, thermal noise, and the strength of the driving field.
