Simplified Quantum Logic with Trapped Ions

January 1, 1997
Author(s)
C Monroe, Dietrich Leibfried, B E. King, D M. Meekhof, Wayne M. Itano, David J. Wineland
We describe a simplified scheme for quantum logic with a collection of laser-cooled trapped atomic ions. Building on the scheme of Cirac and Zoller, we show how the fundamental controlled- NOT gate between a collective mode of ion motion and the internal

Dimensional Inspection Planning Based on STEP and DMIS

Detectability of Slow Crack Growth in Bridge Seels by Acoustic Emission

December 1, 1998
Author(s)
Marvin A. Hamstad, Joseph D. McColskey
The detectabillity of slow crack growth of cracks in bridge steels has been studied by use of acoustic emission testing technology. Fatigue crack-growth rates of nominally 1x10 -4 mm/cycle (4x10 -6 in./cycle) and 1x10 -3 mm/cycle (4x10-5 in/cycle) were

On the Importance of Firebrand Processes in Large Outdoor Fires

May 15, 2019
Author(s)
Samuel L. Manzello
Firebrands are produced from combustion of both vegetative and structural fuels in large outdoor fires. It is well known that firebrand generation, transport, and ignition mechanisms result in rapid and potentially devastating fire spread processes in

NIST Cloud Computing Reference Architecture

September 8, 2011
Author(s)
Fang Liu, Jin Tong, Jian Mao, Robert B. Bohn, John V. Messina, Mark L. Badger, Dawn M. Leaf
The adoption of cloud computing into the Federal Government and its implementation depend upon a variety of technical and non-technical factors. A fundamental reference point, based on the NIST definition of Cloud Computing, is needed to describe an

The Cooper Pair Transistor

September 17, 2010
Author(s)
Jose A. Aumentado
The Cooper pair transistor (CPT) is a superconducting electrometer that has applications in quantum information as well as fundamental superconductivity studies. Since it operates in a near-dissipationless mode, it has potential as a minimally invasive
