D-Wave Chip Passes Rigorous Tests
2014/3/20
With cutting-edge technology, sometimes the first step scientists face is just making sure it actually works as intended.
The USC Viterbi School of Engineering is home to the USC-Lockheed Martin...
世界上第一家商业化的量子计算公司——加拿大D-Wave系统公司近日宣布，其最新开发的512-qubit“D-Wave Two”量子计算机将安装在美国国家航空航天局新建的量子人工智能实验室。该实验室是美国国家航空航天局、谷歌公司及大学太空研究协会（Universities Space Research Association，USRA）共同建立的，隶属于美国国家航空航天局艾姆斯研究中心（Ames R...
Surfatron acceleration of a relativistic particle by electromagnetic plane wave
Surfatron acceleration relativistic particle electromagnetic plane wave
2010/11/16
We study motion of a relativistic charged particle in a plane slow electromagnetic wave and background uniform magnetic field. The wave propagates normally to the background field. Under certain condi...
An alternative approach to exact wave functions for time-dependent coupled oscillator model of charged particle in variable magnetic field
time-dependent coupled oscillator model charged particle variable magnetic field
2010/11/4
A general treatment of the quantal time-dependent coupled oscillators in presence of the variable magnetic field is presented. The treatment is based on the use of an alternative canonical transforma...

Nonlinear Quantum Wave Equation Radiation Electron
2010/3/10
As well known, an electron will produce radiative reaction force when the electron emits electromagnetism radiation. The electron radiative effect had not been considered in Schr\"{o}dinger wave equat...
Role of t-channel meson exchanges in S-wave πN and KN scatterings
meson exchange K-matrix πK KN
2009/8/14
The low-energy S-wave πN and KN scatterings are studied by using the K-matrix approach within the meson exchange framework. The t-channel meson exchanges, especially ρ and σ exchanges, are found to pl...
Simulation of Millimeter-Wave Gunn Oscillations in Gallium Nitride
High field transport Millimeter-Wave Gunn Oscillations
2010/4/12
High field transport in wide bandgap semiconductors like GaN is of great technological importance. The negative differential mobility regime at high fields, under suitable conditions, can lead to mill...
Mesoscopic d-Wave Qubits: Can High-Tc Cuprates Play a Role in Quantum Computing?
high-Tc Josephson T-breaking d-wave qubit decoherence design scalability
2010/4/12
Due to nontrivial orbital pairing symmetry, surfaces and interfaces of high-Tc superconductors support states which violate time-reversal (T-) symmetry. Such naturally degenerate states, useful as wor...
