    • Atom localization via phase and amplitude control of the driving field 
      Ghafoor, F.; Qamar, S.; Zubairy, M. Suhail (American Physical Society, 2002)
      Control of amplitude and phase of the driving field in an atom-field interaction leads towards the strong line narrowing and quenching in the spontaneous emission spectrum. We exploit this fact for the atom localization ...
    • Quantum state measurement using phase-sensitive amplification in a driven three-level atomic system 
      Ahmad, M.; Qamar, S.; Zubairy, M. Suhail (American Physical Society, 2001)
      Phase-sensitive amplification in a three-level atomic system exhibits interesting features. For example, in the zero-detuning limit and for sufficiently strong driving field, this system becomes an ideal parametric amplifier, ...
    • Reconstruction of a multimode entangled state using a two-photon phase-sensitive linear amplifier 
      Ahmad, M.; Qamar, S.; Zubairy, M. Suhail (American Physical Society, 2003)
      We propose a model for the measurement of an arbitrary multimode entangled state of the cavity field using two-photon correlated emission laser. We consider two cases: (a) The modes have different frequencies and are ...
    • Spectroscopic measurement of an atomic wave function 
      Kapale, KT; Qamar, S.; Zubairy, M. Suhail. (American Physical Society, 2003)
      We present a simple spectroscopic method based on Autler-Townes spectroscopy to determine the center-of-mass atomic wave function. The detection of spontaneously emitted photons from a three-level atom, in which two upper ...
    • Teleportation of an atomic momentum state 
      Qamar, S.; Zhu, S. Y.; Zubairy, M. Suhail. (American Physical Society, 2003)
      In this paper, we propose a scheme for teleportating a superposition of atomic center-of-mass momentum states to a superposition of the cavity field using quantum controlled-NOT gate via atomic scattering in the Bragg ...
