Time and Frequency Bulletin

January 1, 2004
Author(s)
Eyvon Petty
The Time and Frequency Bulletin provides information on performance of time scales and a variety of broadcasts (and related information) to users of the NIST services.

TIN Techniques for Data Analysis and Surface Construction

January 1, 2004
Author(s)
Christoph J. Witzgall, Javier Bernal, Geraldine Cheok
This report addresses the task of meshing point clouds by triangulated elevated surfaces referred to as TIN surfaces. It describes the general features of this approach, and refers to prototype TIN software employed at NIST for research into the analysis

Tip Characterization for Dimensional Nanometrology

January 1, 2004
Author(s)
John S. Villarrubia
Abstract: Technological trends are increasingly requiring dimensional metrology at size scales below a micrometer. Scanning probe microscopy has unique advantages in this size regime, but width and roughness measurements must be corrected for imaging

Toward Heisenberg-Limited Spectroscopy with Multiparticle Entangled States

January 1, 2004
Author(s)
Dietrich G. Leibfried, Murray D. Barrett, T Schaetz, Joseph W. Britton, J Chiaverini, Wayne M. Itano, John D. Jost, Christopher Langer, David J. Wineland
The precision in spectroscopy of any quantum system is fundamentally limited by the Heisenberg uncertainty relation for energy and time. For N systems, this limit requires that they be in a quantum-mechanically entangled state. We describe a scalable
