Measurement crosstalk between two phase qubits coupled by a coplanar waveguide

September 14, 2010
Author(s)
Fabio Altomare, Katarina Cicak, Mika A. Sillanpaa, Michael S. Allman, Dale Li, Adam J. Sirois, Joshua Strong, Jae Park, Jed D. Whittaker, Raymond W. Simmonds
We investigate measurement crosstalk in a system with two flux-biased phase qubits coupled by a resonant coplanar waveguide cavity. After qubit measurement, the superconducting phase undergoes damped oscillations in a deep anharmonic potential producing a

The Thermodynamic Properties of Propane: From p-r-T to the Equation of State

September 14, 2010

Mark O. McLinden, Eric W. Lemmon
The p-ρ-T behavior of high-purity (99.999%) propane was measured from 265 K to 500 K with pressures to 36 Mpa using a two-sinker densimeter. The measurements extend from low-density vapor to compressed liquid states, and the near-critical region was

Energy Absorption Measurements to Standardize Foam in Stab Testing

September 13, 2010
Author(s)
Aaron M. Forster, Diane Mauchant, Elizabeth Wailes, Amanda L. Forster, Michael A. Riley, Kirk D. Rice
Polymer foams serve an important role in the assessment and certification of stab resistant body armor for both US and UK standards. A composite of neoprene and polyethylene foam is used behind the armor during testing. The foam mimics stab dynamics by

Recognizing people from dynamic and static faces and bodies: Dissecting identity with a fusion approach

September 13, 2010
Author(s)
Alice J. O'Toole, P. Jonathon Phillips, Samuel Weimer, Dana A. Roark, Julianne Ayadd, Robert Barwick, Joseph Dunlop
The goal of this study was to evaluate human accuracy at identifying people from static and dynamic presentations of faces and bodies. Participants matched identity in pairs of videos depicting people in motion (walking or conversing) and in \best" static

Some four years ago, we took the responsibility for editing this TRANSACTIONS. Our editorial duties have now ended. It has been a privilege and honor to serve our readers and our authors.

In-situ Stress Measurements During Electrodeposition of Au-Ni Alloys

September 10, 2010
Author(s)
Eric Rouya, Gery R. Stafford, Carlos R. Beauchamp, J. A. Floro, R. G. Kelly, Reed L. M., Zangari G.
We investigate the stress evolution in-situ during the potentiostatic electrodeposition of metastable, nanostructured Au-Ni alloy films, and develop a correlation between the alloy nucleation and growth mode, the growth rate, alloy composition and the

Remote sensing and control of phase qubits

September 10, 2010
Author(s)
Dale Li, Fabio C. Da Silva, Danielle Braje, Raymond W. Simmonds, David P. Pappas
We demonstrate a remote sensing design of phase qubits by separating the control and readout circuits from the qubit loop. This design improves measurement reliability because the control readout chip can be fabricated using more robust materials and can

A More General Type A Evaluation

September 9, 2010
Author(s)
Ruediger Kessel, Raghu N. Kacker, Klaus-Dieter Sommer
The evaluation of uncertainty according to the Guide to the Expression of Uncertainty in measurement is the internationally agreed procedure to evaluate the complete result statement in measurement including measurement uncertainty. It distinguishes two

An Analytical Model for Pulse Shape and Electrothermal Stability in Two-Body Microcalorimeters

September 9, 2010
Author(s)
Douglas A. Bennett, Robert D. Horansky, Daniel R. Schmidt, Daniel S. Swetz, Leila R. Vale, Joel N. Ullom, Andrew Hoover, Michael W. Rabin, Nathan J. Hoteling
High resolution superconducting gamma-ray sensors show potential for the more accurate analysis of nuclear material. These devices are part of a larger class of microcalorimeters and bolometers based on transition edge sensors (TESs) that have two distinct

BioPAX A Community Standard for Pathway Data Sharing

September 9, 2010
Author(s)
Robert N. Goldberg, Michael Cary, Erek Demir
BioPAX (Biological Pathway Exchange) is a standard language to represent biological pathways and processes at the molecular and cellular level. Its major use is to facilitate the exchange of pathway data (http://www.biopax.org). Pathway data captures our

Generation of optical coherent-state superpositions by number-resolved photon subtraction from the squeezed vacuum

September 9, 2010
Author(s)
Thomas Gerrits, Scott C. Glancy, Tracy S. Clement, Brice R. Calkins, Adriana E. Lita, Aaron Miller, Aaron J. Miller, Alan L. Migdall, Sae Woo Nam, Richard P. Mirin, Emanuel H. Knill
We have created heralded coherent-state superpositions (CSSs) by subtracting up to three photons from a pulse of squeezed vacuum light. To produce such CSSs at a sufficient rate, we used our high-efficiency photon-number-resolving transition edge sensor to

High Resolution Tunnelling Spectroscopy of a Graphene Quartet

September 9, 2010
Author(s)
Alexander F. Otte, Young Kuk, Yike Hu, David Torrance, Phillip First, Walt A. de Heer, Hongki Min, Shaffique Adam, Mark D. Stiles, Allan H. MacDonald, Joseph A. Stroscio
Electrons in a single sheet of graphene behave quite differently from those in traditional two-dimensional electron systems. Like massless relativistic particles, they have linear dispersion and chiral eigenstates. Furthermore, two sets of electrons
