Electromagnetically induced magnetochiral anisotropy in a resonant medium
(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 ...
Cavity-mediated long-range interaction for fast multiqubit quantum logic operations
(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 ...
Measurement-induced spatial modulation of spontaneous decay and photon arrival times
(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 ...
Inducing disallowed two-atom transitions with temporally entangled photons
(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 ...
Generation of Werner states via collective decay of coherently driven atoms
(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 ...
Quantum correlations between a pair of Raman photons from a single atom under arbitrary excitation condition
(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
(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 ...
