Recently, Zou et al. [Phys. Rev. A 82, 042325 (2010)] pointed out that two arbitrated quantum signature (AQS) schemes are not secure, because an arbitrator cannot arbitrate the dispute between two users when a receiver repudiates the integrity of a s...
We predict by first-principles calculations that Au have strong affinity to He in bcc Fe. The Au-Au bonding in the segregated Au layer at the He bubble surface is stronger than Fe-Fe and Au-Fe interactions; therefore this layer becomes an effective b...
The results of studies of 2006 VV2 and 13170 (1999 HF1) binary asteroids of NEA group, (45) Eugenia and (87) Sylvia triple asteroids, (762) Pulcova and (90) Antiope binary asteroids of the Main Belt are presented. For the asteroid 2006 VV2, color ind...
The presence of amorphous oxide layers can significantly affect the coherent time of superconducting qubits due to their high dielectric loss. Typically, the surface oxides of superconductor films exhibit lossy and unstable behavior when exposed to a...
Realization of practical superconducting quantum computing requires many qubits of long coherence time. Compared to the commonly used Ta deposited on c-plane sapphire, which occasionally form α-Ta (111) grains and \b{eta}-tantalum grains, high quali...
The Religious Landscape Study is a comprehensive survey of more than 35,000 Americans' religious identities, beliefs and practices that's been conducted in 2007, 2014 and 2023-24. Pew Research …
Dec 27, 2022 · Research has to have an element of discovering something new, of creating knowledge. While a literature search is one important part of a research pro ject, it isn’t research in and of itself.
