Gaussian-state entanglement in a quantum beat laser Academic Article uri icon


  • Recently quantum beat lasers have been considered as a source of entangled radiation. 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. © 2011 American Physical Society.
