Decoherence-Free Quantum Memory Using Trapped Ions

January 1, 2001
Author(s)
D Kielpinski, V Meyer, M A. Rowe, C A. Sackett, Wayne M. Itano, C Monroe, David J. Wineland
We demonstrate a decoherence-free quantum memory of one qubit. By encoding the qubit into the decoherence-free subspace (DFS) of a pair of trapped 9Be+ ions, we protect the qubit from environment-induced dephasing that limits the storage time of a qubit

Definitions of Total Estimators of Common Time-Domain Variances

January 1, 2001
Author(s)
David A. Howe, Trudi K. Peppler
This paper summarizes the definitions and properties of frequency and time variance estimators based on the "total" approach. These definitions and properties are not available in one document, yet this statistical approach produces variance estimates with

Design and Evaluation of A Simple Ultralow Vibration Vacuum Environment

January 1, 2001
Author(s)
John R. Lawall, Ernest G. Kessler
A vibration-isolated platform in a high-vacuum environment designed for prototyping optical interferometers is described. The system provides isolation from both seismic and acoustic disturbances with a residual acceleration of 2.9 x 10 -6 m/s 2 rms (root

Design of a Nanoporous Ultra Low-Dielectric Constant Organosilicate

January 1, 2001
Author(s)
S Y. Yang, C S. Pai, O Nalamasu, E Reichmanis, P Mirau, Yaw S. Obeng, J Seputro, Eric K. Lin, V. J. Lee
A new class of organosilicate has been developed that can attain an ultra low-dielectric constant, k of less than 2.0, with high dielectric breakdown strength (> 2 MV/cm). In this approach, a series of triblock polymers, poly(ethylene oxide-b-propylene

Detection of Pinholes in Ultrathin Films by Magnetic Coupling

January 1, 2001
Author(s)
William F. Egelhoff Jr., L Gan, P J. Chen, Cedric J. Powell, Robert McMichael, R A. Fry
When two magnetic films are separated by a nonmagnetic film, pinholes in the nonmagnetic film can allow direct contact and, thereby, magnetic coupling between the two magnetic films. We have studied this coupling by having one of the magnetic films pinned

Determining Privileges of Mobile Agents

January 1, 2001
Author(s)
Wayne Jansen
This paper describes a method for controlling the behavior of mobile agent-system entities through the allocation of privileges. Privileges refer to policy rules that govern the access and use of computational resources and services by mobile agents. Our

Developmental validation of the VersaPlex(tm) 27PY system

January 1, 2001
Author(s)

Kristy Lenz, Dawn Rabbach, Chao Liu, Quyi Xu, Ying Zeng, Becky Steffen, Douglas Storts

The VersaPlex™ 27PY System is an STR multiplex from Promega offering co-amplification of 27 loci. This six-dye multiplex was designed for casework samples and includes loci that meet database requirements for the US (CODIS), Europe (ESS) and China (Chinese

Dielectric Properties and Microstructure of Ca 5 Nb 2 Ti0 12 and Ca 5 Ta 2 TiO 12

January 1, 2001
Author(s)
Leonid A. Bendersky, J J. Krajewski, R J. Cava
The 1 MHz dielectric properties of Ca 5Nb 2TiO 12 and Ca 5Ta 2TiO 12 compounds were reported recently. Both compounds have a common characteristic dependence of the temperature coefficient of dielectric constant (TCK) and dielectric constant Epilson (sub r
