    • Cavity-mediated long-range interaction for fast multiqubit quantum logic operations 

      Kapale, Kishore T.; Agarwal, Girish S.; Scully, Marlan O. (American Physical Society, 2005-11-04)
      Interactions among qubits are essential for performing two-qubit quantum logic operations. However, nature gives us only nearest neighbor interactions in simple and controllable settings. Here we propose a strategy to ...

    • Electromagnetically induced magnetochiral anisotropy in a resonant medium 

      Sautenkov, V. A.; Rostovtsev, Y. V.; Chen, H.; Hsu, P.; Agarwal, Girish S.; Scully, M. O. (American Physical Society, 2005-06-14)
      Chirality has been extensively studied for well over a century, and its potential applications range from optics to chemistry, medicine, and biology. Ingenious experiments have been designed to measure this naturally small ...

    • Generation of Werner states via collective decay of coherently driven atoms 

      Agarwal, Girish S.; Kapale, Kishore T. (American Physical Society, 2006-02-08)
      We show deterministic generation of Werner states as a steady state of the collective decay dynamics of a pair of neutral atom coupled to a leaky cavity and strong coherent drive. We also show how the scheme can be extended ...

    • Inducing disallowed two-atom transitions with temporally entangled photons 

      Muthukrishnan, Ashok; Agarwal, Girish S.; Scully, Marlan O. (American Physical Society, 2004-08-25)
      Two uncoupled two-level atoms cannot be jointly excited by classical light under general circumstances, due to destructive interference of excitation pathways in two-photon absorption. However, with temporally entangled ...

    • Measurement-induced spatial modulation of spontaneous decay and photon arrival times 

      von Zanthier, Joachim; Bastin, Thierry; Agarwal, Girish S. (American Physical Society, 2006-12-20)
      We report a way of manipulating the spontaneous emission process leading to a spatial modulation of spontaneous decay. The effect is observed in the case of coherently driven atoms separated by less than a transition ...

    • Quantum correlations between a pair of Raman photons from a single atom under arbitrary excitation condition 

      Patnaik, Anil K.; Agarwal, Girish S.; Ooi, C. H. Raymond; Scully, Marlan O. (American Physical Society, 2005-10-19)
      The quantum correlation between a pair of Stokes and anti-Stokes photons, involving a Raman emission process is calculated. All realistic radiative and nonradiative decays are included in the calculation and the photon ...

    • Quantum disentanglement eraser: A cavity QED implementation 

      Zubairy, M. Suhail; Agarwal, Girish S.; Scully, Marlan O. (American Physical Society, 2004-07-29)
      A possible experimental scheme of the Garisto-Hardy disentanglement eraser based on a cavity QED system is presented. This scheme can be used for a delayed choice quantum eraser. It also allows us to acquire single-qubit ...
