Sub- and superluminal propagation of intense pulses in media with saturated and reverse absorption
(American Physical Society, 2004-05-19)
We develop models for the propagation of intense pulses in solid state media which can have either saturated absorption or reverse absorption. We model subluminal propagation in ruby and superluminal propagation in alexandrite ...
Langevin analysis of fundamental noise limits in coherent anti-Stokes Raman spectroscopy
(American Physical Society, 2005-01-04)
We use a Langevin approach to analyze the quantum noise in coherent anti-Stokes Raman spectroscopy in several experimental scenarios: with continuous-wave input fields acting simultaneously and with fast sequential pulsed ...
Photon-photon correlations as a probe of vacuum-induced coherence effects
(American Physical Society, 2008-03-27)
We show how the effects of vacuum-induced coherence can be realized by studying photon-photon correlation in the pi-polarized fluorescence in the j=1/2 to j=1/2 transition. These effects should thus be observable in ...
Laser-induced resonance shifts of single molecules self-coupled by a metallic surface
(American Physical Society, 2007-04-05)
The spectral properties of single molecules placed near a metallic surface are investigated at low temperatures. Because of the high quality factor of the optical resonance, a laser-induced shift of the molecular lines is ...
Nonclassical imaging for a quantum search of trapped ions
(American Physical Society, 2004-12-27)
We discuss a simple search problem which can be pursued with different methods, either on a classical or on a quantum basis. The system is represented by a chain of trapped ions. The ion to be searched is a member of that ...
Transport and quantum walk of nonclassical light in coupled waveguides
(American Physical Society, 2008-10-08)
We study the transport and quantum walk of nonclassical light in an array of coupled waveguides which have properties like very low decoherence and thus making them ideal for storage of quantum information. We show how ...
Entanglement of two distant Bose-Einstein condensates by detection of Bragg-scattered photons
(American Physical Society, 2008-07-31)
We show that it is possible to generate entanglement between two distant Bose-Einstein condensates by detection of Hanbury-Brown-Twiss-type correlations in photons Bragg scattered by the condensates. Upon coincident detection ...
Ultraslow light in inhomogeneously broadened media
(American Physical Society, 2006-04-19)
We calculate the characteristics of ultraslow light in an inhomogeneously broadened medium. We present analytical and numerical results for the group delay as a function of power of the propagating pulse. We apply these ...
Quantum logic gates using Stark-shifted Raman transitions in a cavity
(American Physical Society, 2004-06-04)
We present a scheme to realize the basic two-qubit logic gates such as quantum phase gate and controlled-NOT gate using a detuned optical cavity interacting with a three-level Raman system. We discuss the role of Stark ...
Subwavelength atom localization via coherent population trapping
(IOP Publishing, 2006-08-14)
We present an atom localization scheme based on coherent population trapping. We consider atomic transitions in a Lambda configuration where the control field is a standing-wave field. The probe field and the control field ...
