    • Entanglement conditions for two-mode states: Applications 
      Hillery, Mark; Zubairy, M. Suhail (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 ...
    • Entanglement criteria and nonlocality for multimode continuous-variable systems RID B-8901-2008 
      Sun, Qingqing; Nha, Hyunchul; Zubairy, M. Suhail (American Physical Society, 2009)
      We demonstrate how to efficiently derive a broad class of inequalities for entanglement detection in multimode continuous variable systems. The separability conditions are established from partial transposition (PT) in ...
    • Entanglement of Gaussian states using a beam splitter RID A-4660-2010 RID B-8901-2008 
      Tahira, Rabia; Ikram, Manzoor; Nha, Hyunchul; Zubairy, M. Suhail (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 ...
    • Quantum beat laser as a source of entangled radiation 
      Qamar, Shahid; Ghafoor, Fazal; Hillery, Mark; Zubairy, M. Suhail (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 ...
