基于数据仓库的EIS在CIMS中的研究与实现

随着信息系统在企业应用的不断发展，越来越多的企业高层领导已不满足从ＭＩＳ、ＭＲＰＩＩ中获取的信息．本文结合在企业实际中应用的ＪＳＣＩＭＳ领导信息系统，首先介绍了ＣＩＭＳ环境下企业领导对信息系统的需求，然后给出了ＥＩＳ的概念和ＥＩＳ的ＣＳＦｓ，并在通用数据仓库模型基础上，提出了ＪＳＣＩＭＳ中ＥＩＳ数据仓库的模型及建立过程．

Repeat-until-success distributed quantum computation by using single-photon interference at a beam splitter

A repeat-until-success (RUS) measurement-based scheme for the implementation of the distributed quantum computation by using single-photon interference at a 50:50 beam splitter is proposed. It is shown that the 50:50 beam splitter can naturally project a suitably encoded matter-photon state to either a desired entangling gate-operated state of the matter qubits or to their initial state when the photon is detected. The recurrence of the initial state permits us to implement the desired entangling gate in a RUS way. To implement a distributed quantum computation we suggest an encoding method by means of the effect of dipole-induced transparency proposed recently [E. Waks and J. Vuckovic, Phys. Rev. Lett. 96, 153601 (2006)]. The effects of the unfavorable factors on our scheme are also discussed.
