Electron Probe Microanalysis

January 1, 2005
Author(s)
Dale Newbury, Kent D. Irwin, Gene C. Hilton, David A. Wollman, John A. Small, John M. Martinis

Enhanced Quantum State Detection Efficiency Through Quantum Information Processing

January 1, 2005
Author(s)
T Schaetz, Murray D. Barrett, Dietrich G. Leibfried, Joseph W. Britton, J Chiaverini, Wayne M. Itano, John D. Jost, E Knill, Christopher Langer, David J. Wineland
We investigate theoretically and experimentally how quantum state-detection efficiency is improved by the use of quantum information processing (QIP). Experimentally, we encode the state of one 9Be ion qubit with one additional ancilla qubit. By measuring

Errors Resulting From the Reflectivity of Calibration Targets

January 1, 2005
Author(s)
James P. Randa, Dave K. Walker, Robert L. Billinger, Amanda E. Cox
For a microwave total power radiometer, we consider the error introduced by neglecting the difference int he antenna reflection coefficient between when it views a distant scene and a nearby calibration target. An approximate expression is presented for

Evaluation and Selection Ad Hoc Group Update, IEEE 802.21-05-214-01

January 1, 2005
Author(s)
Nada T. Golmie
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Extinguishment of Cup-Burner Flames in Low Gravity

January 1, 2005
Author(s)
F Takahashi, Gregory T. Linteris, V Katta
The effects of oxidizer stream velocity and oxygen concentration, as well as gravity and pressure, on the extinguishment limits of laminar co-flow diffusion flames of methane, formed in a cup-burner apparatus, have been studied experimentally and
