Streaming universal distortion-free entanglement concentration
Robin Blume-Kohout, Sarah Croke, Daniel Gottesman
This paper presents a streaming (sequential) protocol for universal entanglement concentration at the Shannon bound. Alice and Bob begin with N identical (but unknown) two-qubit pu…
Calculation of chemical reaction energies using the AM05 density functional
Richard P. Muller, Ann E. Mattsson, Curtis L. Janssen
We present results that compare the accuracy of the AM05 density functional to a set of chemical reaction energies. The reactions were generated from the singlet species in the wel…
Diameter-Dependent Electronic Transport Properties of Au-Catalyst/Ge-Nanowire Schottky Diodes
François Léonard, A. Alec Talin, B. S. Swartzentruber +1
We present electronic transport measurements in individual Au-catalyst/Ge-nanowire interfaces demonstrating the presence of a Schottky barrier. Surprisingly, the small-bias conduct…
Pure quantum dephasing of a solid state electron spin qubit in a large nuclear spin bath coupled by long-range hyperfine-mediated interactions
L. Cywinski, W. M. Witzel, S. Das Sarma
We investigate decoherence due to pure dephasing of a localized spin qubit interacting with a nuclear spin bath. Although in the limit of a very large magnetic field the only decoh…
Temperature-dependent transport in a sixfold degenerate two-dimensional electron system on a H-Si(111) surface
Robert N. McFarland, Tomasz M. Kott, Luyan Sun +2
Low-field magnetotransport measurements on a high mobility (mu=110,000 cm^2/Vs) two-dimensional (2D) electron system on a H-terminated Si(111) surface reveal a sixfold valley degen…
