The Design of Fault Tolerant Quantum Dot Cellular Automata Based Logic
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.

Quantum dots cellular automata: fault tolerant universal logic gates
The main promise of Quantum Dot Cellular Automata (QCA) as a new computing paradigm is the possbility of implementing a set of universal logic gates and thus feasibility of general-purpose computing.
