Realization of a programmable two-qubit quantum processor

November 15, 2009
Author(s)
David Hanneke, Jonathan Home, John D. Jost, Jason Amini, Dietrich G. Leibfried, David J. Wineland
The universal quantum computer is a device that could simulate any physical system and represents a major goal for the field of quantum information science. Algorithms performed on such a device are predicted to offer significant gains for some important

Is There a High Energy Particle Population in the Quiet Solar Corona?

December 6, 2006
Author(s)
Yuri Ralchenko, Uri Feldman, G. A. Doschek
A study of spectra emitted by the quiet solar corona indicates that the majority of line intensities originating in low-lying levels are consistent with isothermal plasma of ~1.3 106 K. Nevertheless, a number of line intensities and in particular those

From Stable Lasers to Optical-Frequency Clocks

Analysis of Uncertainties in Stray-Light Correction

December 1, 2010
Author(s)
Yuqin Zong
Measurement errors arising from stray light within a spectroradiometer are often the dominant source of uncertainty and are difficult to reduce. However, the stray-light errors can be corrected by using a stray-light correction matrix that is derived from

Laser Focusing of Atoms: A Particle Optics Approach

September 1, 1991
Author(s)
Jabez J. McClelland, M Scheinfein
The use of a TEM 01 *-mode laser beam has been proposed as a means of focusing an atomic beam to nanometer-scale spot diameters. We have analyzed the classibal trajectories of atoms through a TEM 01 *-mode laser beam using methods developed for particle

Laser Focusing of Atoms: A Particle Optics Approach

January 1, 1990
Author(s)
Jabez J. McClelland, M Scheinfein
The use of TEM* 01 ("donut") mode laser beam has been proposed as a means of focusing an atomic beam to nanometer scale spot diameters. We have analyzed the classical trajectories of atoms through a donut mode laser beam using methods developed for
