51. Energy Decay in Josephson Qubits from Non-equilibrium Quasiparticles
Topic: Physics
Published: 8/26/2009
Authors: Jose Alberto Aumentado, John M Martinis, M Ansmann
Abstract: We calculate the energy decay rate of Josephson qubits and superconducting resonators from non-equilibrium quasiparticles. The decay rates from experiments are shown to be consistent with our predictions based on a prior measurement of the quasipar ...

52. Energy Levels and Observed Spectral Lines of Neutral and Singly Ionized Titanium, Ti I and Ti II
Series: J. Phys. & Chem. Ref. Data (JPCRD)
Topic: Physics
Published: 1/12/2012
Author: Edward Barry Saloman
Abstract: The energy levels and observed spectral lines of neutral and singly ionized titanium atoms have been compiled. Tables of energy levels and spectral lines are generated for each stage. Experimental g-factors and leading percentages are included when ...

53. Enhancing Image Contrast Using Coherent States and Photon Number Resolving Detectors
Topic: Physics
Published: 3/15/2010
Authors: Aaron Pearlman, Alexander E. Ling, Elizabeth A Goldschmidt, Jingyun Fan, Christoph Wildfeuer, Alan L Migdall
Abstract: We experimentally map the transverse profile of diffraction-limited beams using photon number resolving detectors. We observe strong compression of diffracted beam profiles for high detected photon number. This effect leads to higher contrast than ...

54. Enriching 28Si beyond 99.9998 % for semiconductor quantum computing
Topic: Physics
Published: 8/5/2014
Authors: Kevin Joseph Dwyer, Joshua M Pomeroy, David S Simons, June Waiyin Lau, Kristen L. Steffens
Abstract: Using a laboratory-scale apparatus, we enrich 28Si to 40 times better than previously reported starting from natural abundance silane gas and offer another source for providing these critical materials from the industrial gas centrifuge methods. ...

55. Entangling Light in its Spatial Degrees of Freedom with 4-Wave Mixing in an Atomic Vapor
Topic: Physics
Published: 2/18/2009
Authors: Vincent Boyer, Alberto Manuel Marino, Raphael C. Pooser, Paul D Lett
Abstract: The entanglement properties of two beams of light can reside in subtle correlations that exist in the unavoidable quantum fluctuations of the amplitudes and the phases of the electric fields. Recent advances in the generation of nonclassical light w ...

56. Evaluation of a GPS Receiver for Code and Carrier-Phase Time and frequency Transfer
Topic: Physics
Published: 11/15/2010
Authors: Victor Shufang Zhang, Michael A Lombardi
Abstract: We evaluate a dual-frequency, multi-channel GPS receiver for time and frequency transfer applications. The receiver is able to lock its internal clock to an external reference frequency and synchronize the receiver clock to an external timing signal. ...

57. Experimental Parameters for a Reactor Antineutrino Experiment at Very Short Baselines
Topic: Physics
Published: 4/23/2013
Author: Hans P Mumm
Abstract: Reactor antineutrinos are used to study neutrino oscillation, search for signatures of non-standard neutrino interactions, and to monitor reactor operation for safeguard applications. The flux and energy spectrum of reactor antineutrinos can be predi ...

58. Experimental Uhrig Dynamical Decoupling Using Trapped Ions
Topic: Physics
Published: 6/25/2009
Authors: Michael J. Biercuk, Hermann Uys, Aaron Vandevender, Nobuyasu Shiga, Wayne M Itano, John J Bollinger
Abstract: We present a detailed experimental study of the Uhrig Dynamical Decoupling (UDD) sequence in a variety of noise environments. Our qubit system consists of a crystalline array of ^u9^Be^u+^ ions confined in a Penning trap. We use an electron-spin-fli ...

59. Extension of the NIST spectral power-responsivity calibration service to 2500 nm
Topic: Physics
Published: 3/2/2012
Authors: George P Eppeldauer, Howard W Yoon, Jinan Zeng, Thomas C Larason, Jeanne M Houston, Vladimir Khromchenko
Abstract: The National Institute of Standards and Technology (NIST) is working to extend the upper wavelength limit of the spectral power-responsivity calibration service from 1800 nm to 2500 nm. This extension is based on extended-InGaAs (EIGA) transfer- and ...

60. Extension of the NIST tristimulus colorimeter for solid-state light source measurements
Topic: Physics
Published: 5/29/2009
Authors: George P Eppeldauer, Carl C Miller, Thomas C Larason, Yoshihiro Ohno
Abstract: In order to obtain improved color measurement uncertainties for solid state light (SSL) sources, the second generation tristimulus colorimeter of NIST has been extended with a fifth channel to perform efficient matrix corrections for the spectral mis ...
