The Design of Fault Tolerant Quantum Dot Cellular Automata Based Logic
Curtis D. Armstrong, William M. Humphreys, Amir Fijany · NASA Technical Reports Server (NASA) · 2002
As transistor geometries are reduced, quantum effects begin to dominate device performance. At some point, transistors cease to have the properties that make them useful computational components. New computing elements must be developed in order to keep pace with Moore s Law. Quantum dot cellular automata (QCA) represent an alternative paradigm to transistor-based logic. QCA architectures that are robust to manufacturing tolerances and defects must be developed. We are developing software that allows the exploration of fault tolerant QCA gate architectures by automating the specification, simulation, analysis and documentation processes.
