Cavity QED implementation of the discrete quantum Fourier transform
(American Physical Society, 2002)
We present a scheme for the implementation of the discrete quantum Fourier transform using cavity quantum electrodynamics. In the proposed scheme a series of atoms whose atomic coherence carries the input state passes ...
Resonant enhancement of high-order optical nonlinearities based on atomic coherence RID A-1272-2007
(American Physical Society, 2002)
We show that the effect of coherent population trapping may result in resonant enhancement of chi((5)) or higher-order nonlinearities. The enhancement is accompanied by suppression of the other linear and nonlinear ...
Two-time intensity correlation in a driven three-level system
(American Physical Society, 1996)
We examine the various two-time fluorescence intensity correlations emitted by a driven three-level atom in a cascade configuration. For a strongly driven atom, the two intensity autocorrelation functions, one from the ...
Condensation of N bosons. II. Nonequilibrium analysis of an ideal Bose gas and the laser phase-transition analogy
(American Physical Society, 2000)
A nonequilibrium approach to the dynamics and statistics of the condensate of an ideal N-atom Bose gas cooling via interaction with a thermal reservoir using the canonical ensemble is developed. We derive simple analytical ...
Compensation of ac Stark shifts in optical magnetometry RID B-9041-2008 RID A-1272-2007
(American Physical Society, 2001)
The ac Stark shift of the resonance frequency of the nonlinear magneto-optic effect (NMOE) results in a fundamental broadening of this resonance which limits the precision of optical magnetometry based on NMOE. We have ...
Theory of femtosecond coherent anti-Stokes Raman backscattering enhanced by quantum coherence for standoff detection of bacterial spores
(American Physical Society, 2005)
Backscattered signal of coherent anti-Stokes Raman spectroscopy can be an extremely useful tool for remote identification of airborne particles, provided the signal is sufficiently large. We formulate a semiclassical theory ...
Quantum search protocol for an atomic array
(American Physical Society, 2001)
Quantum computers can, in principle, exceed the speed of ordinary computers by taking advantage of quantum coherence and entanglement. It is possible to find a "needle in a haystack" of N-1 straws in only rootN searches ...
