The Decoherence-Free in Multi-Coupled Quantum Computing System

wuhan university Journal of Natural Sciences 1999年第4期4卷 428-434页

作者： liu gui ping, bi qiao,{2. qing jie state key Laboratory of advanced technology for materials synthesis and processing,{12., wuhan 43.070, china wuhan university of {2. State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan China (GRID:grid.162110.5) (ISNI:***)

A subdynamics theory framework for describing multi coupled quantum computing systems is presented first. A general kinetic equation for the reduced system is given then, enabling a sufficient condition to be formulated for constructing a pure coherent quantum computing system. This reveals that using multi coupled systems to perform quantum computing in Rigged Liouville Space opens the door to controlling or eliminating the intrinsic de coherence of quantum computing systems.

晶粒细化是提高bi_(2.Te_(3)基热电材料力学性能的重要方法,但晶粒细化过程中伴随的类施主效应严重劣化了材料的热电性能,并且一旦产生类施主效应,就很难通过简单的热处理等工艺消除.本文系统研究n型bi_(2.Te_(3)基化合物烧结前粉体颗粒尺寸对材料类施主效应和热电性能的影响规律.随着颗粒尺寸减小,氧诱导的类施主效应明显增强,载流子浓度从10 M烧结样品的3.36×10^(19)cm^(-3)急剧增加到12. M烧结样品的7.33×10^(19)cm^(-3),严重偏离最佳载流子浓度2.51×10^(19)cm^(-3),热电性能严重劣化.当粉体颗粒尺寸为1—2.mm时,烧结样品的Seebeck系数为–195 μV/K,载流子浓度为3.36×10^(19)cm^(-3),与区熔样品沿着ab面方向的Seebeck系数为–2.3 μV/K和载流子浓度为2.51×10^(19)cm^(-3)相近,未表现出明显的类施主效应,可作为粉末冶金工艺的优质原料. 18 M烧结样品获得最大ZT值为0.75,进一步增强织构有望获得优异的热电性能.本研究为调控和有效抑制类施主效应的产生提供了新方法和途径,为采用粉末冶金工艺制备具有优异热电性能和力学性能材料提供了重要指导.

采用一种简单的无模板水热合成法制备了具有分级结构的钨酸铋纳米花,并将钨酸铋纳米花材料应用于可见光催化去除水中的四环素类抗生素。通过X射线粉末衍射、扫描电镜、透射电镜、紫外固体漫反射、比表面分析等一系列物理表征对光催化剂和催化反应体系进行了表征。研究结果表明钨酸铋纳米光催化剂对四环素类抗生素(四环素和土霉素)均具有良好的降解能力。此外,催化剂对碱性溶液中四环素的降解效率普遍较高,且该催化剂表现出良好的循环稳定性。
