CCR-0210421Wolfgang Porod and Gary H. Bernstein"NER: Computing Architectures for Coupled Nanomagnets"We explore the feasibility of developing computing architecturesimplemented in magnetically-coupled arrays of nanometer-sized dots andpillars. Similar to the electronic Quantum-Dot Cellular Automata (QCA)scheme, which was previously developed by the Notre Dame group,information is encoded in the magnetization of single-domainpermanent-magnet structures, and the physical interaction betweenneighboring magnets provides the local connectivity. The main goal ofthis project is to investigate how logic functions can be realized instructured arrays of coupled nanomagnets. We propose a joint theoreticaland experimental approach to explore the feasibility of such magneticQCA-like architectures for computing and signal processing. Oncefeasibility of elementary logic functions is established, one mayenvision special-purpose cellular processor cells composed of couplednanoscale magnetic sensors and memories. The robustness of such magneticsystems opens the potential for applications where nanometer-sized, yetrugged, systems are required with a wide range of operatingtemperatures.

CCR-0210421沃尔夫冈·波洛德和加里·H·伯恩斯坦：《NER：耦合纳米磁铁的计算体系结构》，我们探讨了开发由纳米尺寸的点和柱组成的磁耦合阵列简化的计算体系结构的可行性。与Notre Dame小组先前提出的电子量子点元胞自动机(QCA)方案类似，信息编码在单畴永磁体结构的磁化强度中，相邻磁体之间的物理相互作用提供局部连接。这个项目的主要目标是研究如何在耦合纳米磁体阵列的指导下实现逻辑功能。我们提出了一种理论和实验相结合的方法来探索这种磁性类QCA结构用于计算和信号处理的可行性。一旦确定了基本逻辑函数的可行性，就可以设想由纳米级磁性传感器和存储器组成的专用细胞处理器单元。这种磁性系统的坚固性为纳米尺寸、但坚固耐用的系统在广泛的工作温度范围内提供了潜在的应用。
