Project ID: 0702705Title: Recon_guration and Defect Tolerance in Quantum-dot Cellular Automata Based Nano-DevicesPI: Xiaobo Sharon HuCo-PIs: Marya Lieberman, Wolfgang PorodInst: University of Notre DameABSTRACTNSF Unit Consideration: CPA - Foundations of Computing Processes and ArtifactsThe proposed work is on constructing reconfigurable logic and devising defect detection, diagnosis and tolerance techniques for Quantum-dot Cellular Automata (QCA) based nano-scale devices. QCA- based devices differ fundamentally from traditional CMOS ones. They have the potential to alleviate challenges from interconnects and power consumption as CMOS device sizes continue to shrink. Basic QCA constructs have been experimentally demonstrated with both semiconductor quantum dots and nano-magnets. Implementing QCA devices with molecular charge containers has also shown greatpromise. Though being a promising computing paradigm, QCA faces a same challenge as all other nano-scale devices. That is, defect rates are expected to be high. Reconfigurable logic and defect tolerance design are considered to be two powerful means to circumvent the effects of high defect rates. This project will significantly extend the state-of-the-art in constructing reconfigurable logic under the QCA model.Successful completion of the project will lead to both novel reconfigurable logic constructs and new defect detection and diagnosis schemes. The proposed work will help predict whether it is practical to fabricate large scale QCA-based reconfigurable circuits, and whether such circuits can become a strong contender as a post-CMOS computing alternative. The proposed work will have a significant impact not only within the design community but also in the physical science community. It will contribute new knowledge in designing reconfigurable logic and circuits in the context of charge-coupled computing models. It will also play an important role in providing valuable feedback to physical scientists working on exploring various technologies for implementing QCA devices. As an integral part of the proposed work, a new course module on QCA- based computing will be developed, which emphasizes the interdisciplinary nature in this excitingresearch area. A systematic endeavor will be made in recruiting undergraduate students, especially from the under-represented groups, to participate in the project.

项目编号：0702705标题：基于量子点元胞自动机的纳米器件的重构和缺陷容限PI：Xiaobo Sharon HuCo-PI：Marya Lieberman，Wolfgang Porod Inst：University of Notre Dame摘要NSF Unit Consideration：CPA - Foundations of Computing Processes and ArtifactsThe proposed work is on constructing reconfigurable logic and develop defect detection，diagnosis and tolerance techniques for Quantum-dot Cellular Automata（QCA）based nano-scale devices.基于QCA的器件与传统的CMOS器件有着根本的不同.随着CMOS器件尺寸的不断缩小，它们有可能缓解互连和功耗带来的挑战。基本的QCA结构已经用半导体量子点和纳米磁体进行了实验证明。用分子电荷容器实现QCA器件也显示出很大的希望。虽然QCA是一种很有前途的计算范例，但它面临着与所有其他纳米级器件相同的挑战。也就是说，预计缺陷率会很高。可重构逻辑和缺陷容限设计被认为是规避高缺陷率影响的两种有力手段。该项目的成功完成将极大地扩展QCA模型下可重构逻辑的构建技术，并将产生新的可重构逻辑结构和新的缺陷检测与诊断方案。所提出的工作将有助于预测它是否是实际的，以制造大规模的QCA为基础的可重构电路，以及这种电路是否可以成为一个强有力的竞争者作为后CMOS计算的替代品。拟议的工作将产生重大影响，不仅在设计界，而且在物理科学界。它将有助于在电荷耦合计算模型的背景下设计可重构逻辑和电路的新知识。它还将在为物理科学家提供有价值的反馈方面发挥重要作用，这些科学家正在探索实施QCA设备的各种技术。作为拟议工作的一个组成部分，将开发一个新的基于QCA的计算课程模块，强调这一令人兴奋的研究领域的跨学科性质。将作出系统的奋进，招募本科生，特别是来自代表性不足的群体，参加该项目。
