    • Advantages of nonclassical pointer states in postselected weak measurements 
      Turek, Yusuf; Maimaiti, W.; Shikano, Yutaka; Sun, Chang-Pu; Al-Amri, M. (Physical Review A - Atomic, Molecular, and Optical Physics, 2015)
    • Controllable optical switch using a Bose-Einstein condensate in an optical cavity 
      Yang, Shuai; Al-Amri, M.; Evers, Joerg; Zubairy, M. Suhail (American Physical Society, 2011)
      The optical bistability of an ultracold atomic ensemble located in a small-volume ultrahigh-finesse optical cavity is investigated. We find that a transverse pumping field can be used to control the bistable behavior of ...
    • Entangled radiation via a Raman-driven quantum-beat laser 
      Qamar, Sajid; Al-Amri, M.; Qamar, Shahid; Zubairy, M. Suhail (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 ...
    • Lamb shift due to surface plasmon polariton modes 
      Sun, Qingqing; Al-Amri, M.; Kamli, Ali; Zubairy, M. Suhail (American Physical Society, 2008)
      The Lamb shift of a hydrogen atom due to the surface plasmon polariton (SPP) modes is calculated and we observe both band edge and surface enhancement. The atom sits inside a thin metal slab which is sandwiched by two ...
    • Probing the quantum commutation rules through cavity QED 
      Sun, Qingqing; Al-Amri, M.; Zubairy, M. Suhail (American Physical Society, 2008)
      We propose a cavity QED-based scheme to observe the noncommutativity between the creation and annihilation operators. By conditional measurement after the atom-field interaction in a cavity, it is possible to achieve a ...
    • Quantum teleportation of four-dimensional qudits 
      Al-Amri, M.; Evers, Joerg; Zubairy, M. Suhail (American Physical Society, 2010)
      A protocol for the teleportation of arbitrary quantum states of four-dimensional qudits is presented. The qudit to be teleported is encoded in the combined state of two ensembles of atoms placed in a cavity at the sender's ...
    • Reversing entanglement change by a weak measurement 
      Sun, Qingqing; Al-Amri, M.; Davidovich, Luiz; Zubairy, M. Suhail. (American Physical Society, 2010)
      Entanglement of a system changes due to interactions with the environment. A typical type of interaction is amplitude damping. If we add a detector to monitor the environment and only select the no-damping outcome, this ...
    • Reversing the weak measurement of an arbitrary field with finite photon number 
      Sun, Qingqing; Al-Amri, M.; Zubairy, M. Suhail. (American Physical Society, 2009)
      For an arbitrary field with finite photon number inside a leaky cavity, we show that the null-result measurement can be conditionally reversed, using either multiple atoms or a multilevel atom. Even with photons detected, ...
    • Subwavelength optical microscopy in the far field 
      Sun, Qingqing; Al-Amri, M.; Scully, Marlan O.; Zubairy, M. Suhail. (American Physical Society, 2011)
      We present a procedure for subwavelength optical microscopy. The identical atoms are distributed on a plane and shined with a standing wave. We rotate the plane to different angles and record the resonant fluorescence ...
    • Sudden death and birth of entanglement in photonic crystals 
      Al-Amri, M.; Li, Gao-xiang; Tan, Rong; Zubairy, M. Suhail (Physical Review A - Atomic, Molecular, and Optical Physics, 2009)
