Entangled radiation via a Raman-driven quantum-beat laser
(American Physical Society, 2009)
We propose a scheme for the entanglement generation of two cavity modes using a four-level Raman-driven quantum-beat laser (QBL). The atomic coherence is generated by a Raman-type two-photon process. Two different sufficient ...
Two-mode single-atom laser as a source of entangled light RID A-5077-2009
(American Physical Society, 2007)
A two-mode single-atom laser is considered, with the aim of generating entanglement in macroscopic light. Two transitions in the four-level gain medium atom independently interact with the two cavity modes, while two other ...
Entanglement generation in a two-mode quantum beat laser RID A-4660-2010
(American Physical Society, 2007)
We analyze the quantum correlations between side modes of a quantum beat laser when a two-level atomic medium is driven strongly by a classical field. The squeezing and the entanglement generation of the cavity radiation ...
Entanglement conditions for two-mode states: Applications
(American Physical Society, 2006)
We examine the implications of several recently derived conditions [Hillery and Zubairy, Phys. Rev. Lett. 96, 050503 (2006)] for determining when a two-mode state is entangled. We first find examples of non-Gaussian states ...
Quantum beat laser as a source of entangled radiation
(American Physical Society, 2008)
We consider a quantum beat laser [Scully and Zubairy, Phys. Rev. A 35 752 (1987)] as a source of entangled radiation. The system essentially consists of three-level atoms inside a doubly resonant cavity such that coherence ...
Entanglement of Gaussian states using a beam splitter RID A-4660-2010 RID B-8901-2008
(American Physical Society, 2009)
We study an experimental scheme to generate Gaussian two-mode entangled states via beam splitter. Specifically, we consider a nonclassical Gaussian state (squeezed state) and a thermal state as two input modes, and evaluate ...
