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 ...
Terbinafine resistance mediated by salicylate 1-monooxygenase in Aspergillus nidulans
(American Society for Microbiology, 2004-09)
Resistance to antifungal agents is a recurring and growing problem among patients with systemic fungal infections. UV-induced Aspergillus nidulans mutants resistant to terbinafine have been identified, and we report here ...
Registration of 'Ok102' wheat

Model selection for discrete dependent variables: Better statistics for better steaks
(Western Agricultural Economics Association, 2004-12)
Little research has been conducted on evaluating out-of-sample forecasts of discrete dependent variables. This study describes the large and small sample properties of two forecast evaluation techniques for discrete dependent ...
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 ...
Donor-acceptor nanoensembles of soluble carbon nanotubes
(Royal Society of Chemistry, 2004-08-10)
Donor-acceptor nanoensembles, prepared via electrostatic interactions of single wall carbon nanotubes and porphyrin salts, give rise to photoinduced intra-complex charge separation that lasts tens of microseconds.
Excess foundry sand characterization and experimental investigation in controlled low-strength material and hot-mixing asphalt
(Office of Scientific and Technical Information (OSTI), 2004-10)
This report provides technical data regarding the reuse of excess foundry sand. The report addresses three topics: a statistically sound evaluation of the characterization of foundry sand, a laboratory investigation to ...
Large two-atom two-photon vacuum Rabi oscillations in a high-quality cavity
(American Physical Society, 2004-10-11)
We predict a large cooperative effect involving two-atom two-photon vacuum Rabi oscillations in a high-quality cavity. The two-photon emission occurs as a result of simultaneous deexcitation of both atoms with two-photon ...
dc-field-induced enhancement and inhibition of spontaneous emission in a cavity
(American Physical Society, 2004-08-20)
We demonstrate how spontaneous emission in a cavity can be controlled by the application of a dc field. The method is specially suitable for Rydberg atoms. We present a simple argument based on Stark shifts for the control ...
Transfer of an unknown quantum state, quantum networks, and memory
(American Physical Society, 2004-08-27)
We present a protocol for transfer of an unknown quantum state. The protocol is based on a two-mode cavity interacting dispersively in a sequential manner with three-level atoms in the Lambda configuration. We propose a ...
