One proposal for a solid-state-based quantum bit (qubit) is to control coupled electron spins on adjacent semiconductor quantum dots. Most experiments have focused on quantum dots made from III-V semiconductors; however, the coherence of electron spins in these materials is limited by hyperfine interactions with nuclear spins. Ge/Si core/shell nanowires seem ideally suited to overcome this limi...

Energy and water availability were identified as the first order controls of evapotranspiration(ET) in ecohyrodrology. With a ~1,000 km precipitation gradient and distinct wet-dry climate,the North Australian Tropical Transect (NATT) was well suited for evaluating how energy andwater availabilities constrain water use by vegetation, but has not been done yet. In this study,we addressed this que...

Adiabatic quantum algorithms represent a promising approach to universal quantum computation. In isolated systems, a key limitation to such algorithms is the presence of avoided level crossings, where gaps become extremely small. In open quantum systems, the fundamental robustness of adiabatic algorithms remains unresolved. Here, we study the dynamics near an avoided level crossing associated w...

Homomorphic encryption is an encryption scheme that allows computations to be evaluated on encrypted inputs without knowledge of their raw messages. Recently Ouyang et al. constructed a quantum homomorphic encryption (QHE) scheme for Clifford circuits with statistical security (or information-theoretic security (IT-security)). It is desired to see whether an informationtheoretically-secure (ITS...

To explore the limitation of a class of quantum algorithms originally proposed for the Hilbert’s tenth problem, we consider two further classes of mathematically nondecidable problems, those of a modified version of the Hilbert’s tenth problem and of the computation of the Chaitin’s Ω number, which is a representation of the Gödel’s Incompletness theorem. Some interesting connection to Quantum ...

UNLABELLED The list of individualized needs of the wheelchair user as developed by the medical and personal profile assessment can be categorized under the general goals to be accomplished through the process of the wheelchair recommendation: MEDICAL PROFILE: MEDICAL HISTORY (1) Compensate for loss or absence of function.

BACKGROUND This study examines the relationship between race and mobility over 5 years in initially well-functioning older adults and evaluates how a broad set of socioeconomic status indicators affect this relationship. METHODS Data were from 2,969 black and white participants aged 70-79 from the Health, Aging, and Body Composition study. Mobility parameters included self-reported capacity t...

OBJECTIVE Compare the quality of life (QOL) of youth living with visible facial differences (FDs) with youth living with a visible nonfacial difference (i.e., mobility limitations), an invisible difference (i.e., attention deficit/hyperactivity disorder), or no known difference. DESIGN An observational study of perceived QOL among adolescents with FDs (n = 56), adolescents with no diagnosed c...

We present improvements to fluorescence sensing in soft-glass microstructured optical fibers that result in significantly improved sensitivity relative to previously published results. Concentrations of CdSe quantum dots down to 10 pM levels have been demonstrated. We show that the primary limitation to the sensitivity of these systems is the intrinsic fluorescence of the glass itself.
