Realization of Greenberg-Horne-Zeilinger （GHZ） and W Entangled States with Multiple Superconducting Quantum-Interference Device Qubits in Cavity QED

An alternative scheme is proposed for generating the Greenberg-Horne-Zeilinger （GHZ） and W types of the entangled states with multiple superconducting quantum-interference device （SQUID） qubits in a single-mode microwave cavity field. In this scheme, there is no transfer of quantum information between the SQUIDs and the cavity, the cavity is always in the vacuum and thus the requirement on the quality of cavity is greatly loosened. In addition, during the process of the generation of the W entangled state, the present method does not involve a real excitation of intermediate levels. Thus, decoherence due to energy relaxation of intermediate levels is minimized.

原子核的单粒子共振态

采用基于相对论平均场的耦合常数解析延拓方法研究球形核的单粒子共振态.具体计算了Zr同位素链中巨晕核的核芯核122Zr阈值附近的中子共振态的能量、宽度和波函数,其结果同相应的散射相移法的结果一致. Using analytic continuation in the coupling constant (ACCC) method within the framework of the self-consistent relativistic mean field (RMF) theory, the energies, widths and wave functions for single-particle resonant states close to the continuum threshold are evaluated. Predictions are also compared with corresponding results obtained by the scattering phase shift method.     

C60量子点与磁性电极的耦合

在磁电子学领域，自旋极化输运与分子器件的结合是一个热门研究方向．最近，来自美国康奈尔大学的Pasupathy等，采用纳米加工技术，将单个C60分子吸附在一对Ni电极之间，构成了“铁磁电极-C60量子点”器件．量子点的Kondo效应和铁磁性交换耦合，原本是相互排斥的，在Pasupathy的实验中，两者被首次结合在一个器件中并加以观察．研究结果表明，如果器件的质量能够保证两种效应之间的竞争得到有效控制，
