    • 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, ...
