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 ...
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 ...
Quantum interferences in cooperative Dicke emission from spatial variation of the laser phase
(American Physical Society, 2008-10-06)
We report generation of a new quantum interference effect in spontaneous emission from a resonantly driven system of two identical two-level atoms due to the spatial variation of the laser phase at the positions of the ...
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 ...
