The Computational Abilities of Random Magnetic Structures

摘要

Quantum-dot cellular automata (QCA) are proposed to replace conventional CMOS techniques for the construction of logic gates. Previous research has shown that QCA are likely to be sensitive to errors in placement of the individual dots within a QCA cell. An approach using random quantum-dot structures claims to partially alleviate the problem of dot placement in a QCA cell. Magnetic versions of QCA are promising candidates for realizing low-power computing devices. In this paper, we investigated the computational abilities of random magnetic structures and compared their behavior with random electronic quantum-dot structures.
