A TDMA Hybrid SQUID Multiplexer

January 25, 2008
Author(s)
Carl D. Reintsema, James A. Beall, W.Bertrand (Randy) Doriese, William Duncan, S. L. Ferreira, Gene C. Hilton, Kent D. Irwin, Dan Schmidt, Joel Ullom, Leila R. Vale, Yizi Xu
We have developed a multiplexed read-out for transition edge sensors based on a hybrid time- and frequency-domain basis set, similar to that used in time-division multiple-access (TDMA) mobile phones. The hybrid basis set uses bandwidth more efficiently

Pulsed Laser Deposition and Characterization of Hf-based High-k Dielectric Thin Films

October 26, 2007
Author(s)
Joseph C. Woicik, M A. Sahiner, Timothy Kurp, Jeffrey Serfass, Marc Aranguren
The continuous downward scaling of the complementary metal oxide semiconductor (CMOS) devices has enabled the Si-based semiconductor industry to meet the technological requirements such as high performance and low power consumption. However, the ever

Advances in Chip-Scale Atomic Frequency References at NIST

September 12, 2007
Author(s)
Svenja A. Knappe, V Shah, Alan Brannon, Vladislav Gerginov, Hugh Robinson, Z Popovic, Leo W. Hollberg, John E. Kitching
We present new advances in the development of chip-scale atomic frequency references. Coherent population trapping (CPT) resonances usually exhibit contrasts below 10 %, when interrogated with frequency modulated lasers. A relatively simple way to increase

Randomized Benchmarking of Quantum Gates

January 1, 2007
Author(s)
Emanuel Knill, D. Leibfried, R. Reichle, J. Britton, R. B. Blakestad, J. D. Jost, C. Langer, R Ozeri, Signe Seidelin, David J. Wineland
A key requirement for scalable quantum computing is that elementary quantum gates can be implemented with sufficiently low error. One method for determining the error behavior of a gate implementation is to perform process tomography. However, standard

Using Laser-Cooled Atoms as a Focused Ion Beam Source

December 1, 2006
Author(s)
James L. Hanssen, E Dakin, Jabez McClelland, M Jacka
The authors describe a new method for creating a high quality focused ion beam using laser-cooled neutral atoms in a magneto-optical trap as an ion source. They show that this new technique can provide spot resolutions and brightness values that are better

SIM Time and Frequency Comparison Network in Near Real Time

October 25, 2006
Author(s)
Jose M. Lopez, Michael A. Lombardi, Andrew N. Novick, Jean-Simon Boulanger, Raymond Pelletier, Carlos Donado
… System (GPS) method to compare frequency and time standards maintained at SIM national metrology laboratories, …

Comparison of MPEG-2 and AVC Coding on Synthetic Test Materials

August 30, 2006
Author(s)
Charles D. Fenimore, John W. Roberts
The available resources for evaluation of moving imagery coding include a variety of subjective and objective methods for quality measurement. These are applied to a variety of imagery, ranging from synthetically-generated to live capture. NIST has created

Automating Thermo-Mechanical Warpage Estimation of PCBs/PCAs using a Design-Analysis Integration Framework

August 18, 2006
Author(s)
Manas Bajaj, Russell Peak, Dirk Zwemer, Thomas Thurman, Lothar Klein, Giedrius Liutkus, Kevin G. Brady, John V. Messina, Mike Dickerson
Accurate prediction, validation and reduction of thermally-induced PCB warpage are critical for enhancing manufacturing yield and reliability in time-to-market driven electronics product realization. In this paper, we describe a methodology to simulate

Quantum Key Distribution System Operating at Sifted-Key Rate over 4 Mbit/s

June 19, 2006
Author(s)
Xiao Tang, Lijun Ma, Alan Mink, Anastase Nakassis, Hai Xu, Barry J. Hershman, Joshua Bienfang, David H. Su, Ronald Boisvert, Charles W. Clark, Carl J. Williams
A complete fiber-based polarization encoding quantum key distribution (QKD) system based on the BB84 protocol has been developed at National Institute of Standard and Technology (NIST). The system can be operated at a sifted key rate of more than 4 Mbit/s

CCQM-K13.1 Subsequent Key Comparison: Cadmium and Lead in Sediment

February 1, 2006
Author(s)
Robert R. Greenberg
CCQM-K13.1 is a Subsequent Key Comparison for Cadmium and Lead in Sediment conducted to provide the opportunity for two NMIs to demonstrate and document improvements in measurement capability achieved since the conduct of CCQM-K13, Amount content of

Face Recognition Based on Frontal Views Generated from Non-Frontal Images

October 1, 2005
Author(s)
V Blanz, Patrick Grother, P. Jonathon Phillips, T Vetter
This paper presents a method for face recognition across large changes in viewpoint. Our method is based on a Morphable Model of 3D faces that represents face-specific information extracted from a dataset of 3D scans. For non-frontal face recognition in 2D
