Prolonging qubit coherence: dynamic decoupling schemes studied in a Penning ion trap

February 2, 2009
Author(s)
Hermann Uys, Michael J. Biercuk, Aaron Vandevender, N. Shiga, Wayne M. Itano, John J. Bollinger
We present a study of dynamical decoupling schemes for the suppression of phase erros due to various noise environments using ions in a Penning ion trap as a model ensemble of qubits. By injecting frequency noise we demonstrate that in an Ohmic noise

Securing Radio Frequency Identification (RFID) Systems

May 17, 2007
Author(s)
Karen A. Scarfone
Radio frequency identification (RFID) is a form of automatic identification and data capture technology that uses electric or magnetic fields at radio frequencies to transmit information. An RFID system can be used to identify many types of objects, such

Field-Induced Formation of Linear, Mesoscopic Polymer Chains From Ferromagnetic Nanoparticles

February 2, 2007
Author(s)
Jason Benkoski, Steven Bowles, Bryan Korth, Ronald L. Jones, Jack F. Douglas, Alamgir Karim, Jeffrey Pyun
Polymer-coated ferromagnetic colloids are first assembled with an applied magnetic field and then permanently fixed into one-dimensional mesostructures using a novel liquid-liquid interfacial system known as Fossilized Liquid Assembly. Using polystyrene

Scalable Register Initialization for Quantum Computing in a Optical Lattice

June 1, 2005
Author(s)
G K. Brennen, G Pupillo, A M. Rey, Charles W. Clark, Carl J. Williams
The Mott insulator state created by loading an atomic Bose-Einstein condensate (BEC) into an optical lattice may be used as a means to prepare a register of atomic qubits in an quantum computer. Such architecture requires a lattice commensurately filled

Comparative Studies of MgB 2 /Mg Nano-Composites and Press-Sintered MgB 2 Pellets

June 1, 2003
Author(s)
Q Li, L Wu, Y Zhu, A R. Moodenbaugh, G Gu, M Suenaga, Z X. Ye, Daniel A. Fischer
We present our studies of superconducting and microstructural properties of bulk MgB 2/Mg nano-composites and press-sintered MgB 2. TEM investigation revealed that the composites are very dense, consisting of nano-sized MgB 2 grains connected by the well

Resonant satellites in photoemission and Auger spectra of d-band metals

March 1, 1981
Author(s)
S Girvin, David R. Penn
Photoemission and Auger electron spectroscopy are powerful tools in the study of the electronic and magnetic properties of d band metals. In certain instances experimental spectra can be directly interpreted as a measure of some one body density of states

Electromagnetics Division: Programs, Activities, and Accomplishments

December 31, 2006
Author(s)
Ronald B. Goldfarb
The Electromagnetics Division is a critical national resource for a wide range of customers. U.S. industry is the primary customer both for the division's measurement services and for technical support on the test and measurement methodology necessary for

Challenges to miniaturizing cold atom technology for deployable vacuum metrology

September 14, 2018
Author(s)
Stephen P. Eckel, Daniel S. Barker, James A. Fedchak, Nikolai N. Klimov, Eric B. Norrgard, Julia K. Scherschligt, Constantinos Makrides, Eite Tiesinga
Cold atoms are excellent metrological tools; they currently realize SI time and, soon, SI pressure in the ultra-high (UHV) and extreme high vacuum (XHV) regimes. The development of primary, vacuum metrology based on cold atoms currently falls under the

Neuromorphic Computing through Time-Multiplexing with a Spin-Torque Nano-Oscillator

December 31, 2017
Author(s)
Mathieu Riou, Flavio Abreu Araujo, Jacob Torrejon, Sumito Tsunegi, Guru Khalsa, Damien Querlioz, Paolo Bortolotti, Vincent Cros, K. Yakushiji, Akio Fukushima, Hitoshi Kubota, Shinji Yuasa, Mark D. Stiles, Julie Grollier
Fabricating powerful neuromorphic chips the size of a thumb requires miniaturizing both hardware synapses and neurons. The challenge for neurons is to scale them down to submicrometer diameters while maintaining the properties that allow for reliable

Structural Effects in the Growth of Giant Magneto Resistance (GMR) Spin Valves

August 1, 2001
Author(s)
M. Menyhard, G. Zsolt, P. J. Chen, Cedric J. Powell, Robert D. McMichael, William F. Egelhoff Jr.
An investigation has been made of the thin-film structure and interface morphology of giant magnetoresistance (GMR) spin valves of the cobalt/copper/cobalt (Co/Cu/Co) type that were grown on polycrystalline NiO substrates at three different temperatures
