Resonator-Assisted Quantum Bath Engineering of a Flux Qubit
Resonator-Assisted Quantum Bath Engineering Flux Qubit
2016/1/22
We demonstrate quantum bath engineering for preparation of any orbital state with the controllable phase factor of a superconducting flux qubit assisted by a microwave coplanar waveguide resonator. We...
Testing Nonclassicality and Non-Gaussianity in Phase Space
Nonclassicality Non-Gaussianity Phase Space
2016/1/22
We theoretically propose and experimentally demonstrate a nonclassicality test of a single-mode field in phase space, which has an analogy with the nonlocality test proposed by Banaszek and Wódkiewicz...
Quantized electromagnetic response of three-dimensional chiral topological insulators
Quantized electromagnetic response three-dimensional chiral topological insulators
2016/1/22
Protected by the chiral symmetry, three-dimensional chiral topological insulators are characterized by an integer-valued topological invariant. How this invariant could emerge in physical observables ...
The router is a key element for a network. We describe a scheme to realize genuine quantum routing of single-photon pulses based on cascading of conditional quantum gates in a Mach-Zehnder interferome...
Quantum Computation under Micromotion in a Planar Ion Crystal
Quantum Computation Micromotion Planar Ion Crystal
2016/1/22
We propose a scheme to realize scalable quantum computation in a planar ion crystal confined by a Paul trap. We show that the inevitable in-plane micromotion affects the gate design via three separate...

可变外场对低维纳米非线性体系热输运的调控研究有利于新型热控制器件的设计。本论文比较分析了用于热输运理论研究的玻尔兹曼方法、格林-库伯方法、非平衡格林函数法和量子主方程的优势和局限性，发现非平衡格林函数方法可处理弱耦合体系在可变外场作用下非线性体系的热输运，4阶量子主方程可处理耦合系数在045以内的中等程度耦合体系。
A general approach to electrical tomography is here described, based on the distribution of the experimental data to the set of voxels in which the subsoil has been divided. This approach utilizes the...
We study a particle moving at unit speed in a channel made by
connected self-similar billiard tables that grow in size by a factor r > 1
from left to right (this model was recently introduced in phy...

Fermi acceleration is a mechanism, first suggested by
Enrico Fermi in 1949, to explain heating of particles in cosmic
rays.
Comparisons of experimental topside electron concentration profiles with IRI and NeQuick models
ionospheric electron comparison profiles
2015/9/25
A critical part of the vertical ionospheric electron concentration profile is the region above its maximum (topside ionosphere) and many attempts have been made to model this region because of the lim...
Investigation of the relative bottomside/topside contribution to the total electron content estimates

2015/9/25
High-resolution vertical electron density true height profiles from Athens Digisonde are used to calculate the electron content up to the peak of the F 2 layer (bottomside electron content) and also t...
在计算流体动力学的实际应用中无反射边界条件是一个重要的研究课题. 文中应用时间插值的特征线方法构造了一种新式的拉氏边界条件,并应用在光滑粒子法中. 该方法与使用特征线方法的欧拉边界条件方法相比,不需要区分超声速和亚声速流的不同,并且在入流和出流中具有相同的形式,因而更加简便易行. 数值结果表明,采用时间插值特征线法的拉氏边界条件方法在稀疏波、激波以及爆轰波的模拟中都能够得到较好的无反射效果.
More Trusting, Less Trust? An Investigation of Early E-commerce in China
Trust, trusting trustworthiness e-commerce
2015/9/21
Trust is vital for market development, but how can trust be enhanced in an online marketplace? A common view is that more trusting of buyers may help to build seller trustworthiness.
Optimal Aggregation of Consumer Ratings: An Application to Yelp.com
crowdsourcing social network e-commerce
2015/9/21
Consumer review websites such as Yelp.com leverage the wisdom of the crowd, with
each product being reviewed many times (some with more than 1000 reviews). Because of
this, the way in which informat...
