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 ...
Anomalous magnetoresistance oscillations and enhanced superconductivity in single-crystal Pb nanobelts
(AIP Publishing, 2008-06-13)
Using atomically flat single-crystal Pb ultrathin films grown on Si(111) substrate by molecular beam epitaxy, we fabricated Pb nanobelts of 28 atomic monolayers thick, 285nm wide, and 10 um long by focus ion beam technique. ...
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 ...
In vitro efficacy of new antifolates against trimethoprim-resistant Bacillus anthracis
(American Society for Microbiology, 2007-12)
Bacillus anthracis is innately resistant to trimethoprim (TMP), a synthetic antifolate that selectively inhibits several bacterial dihydrofolate reductases (DHFRs) but not human DHFR. Previously, we were able to confirm ...
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 ...
Portable near-infrared diffusive light imager for breast cancer detection
(SPIE, the international society for optics and photonics, 2004-02-03)
We present a frequency-domain near-infrared optical tomography system designed for breast cancer detection, in conjunction, with conventional ultrasound. It features fast optical switching, threewavelength excitations, and ...
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 ...
Environment for scholarship in agricultural economics extension
(Cambridge University Press, 2006-08)
Although opportunities and challenged for the Cooperative Extension Service have been addressed in the agricultural economics literature, little attention has been paid to the extension scholar. This atrticle relates Boyer's ...
Mysterious mycorrhizae? A field trip and classroom experiment to demystify the symbioses formed between plants and fungi
(University of California Press, 2009-09)
