In recent years Field-Coupled devices, like Quantum dot Cellular Automata, are gaining an ever increasing attention from the scientific community. The computational paradigm beyond this device topology is based on the interaction among neighbor cells to propagate information through circuits. Among the various implementations of this theoretical principle, NanoMagnet Logic (NML) is one the most...

Quantum dot cellular Automata technology is used in this paper which overcomes the design constraints of nanoscale CMOS circuits. This paper presents the analysis of 2:4 decoder circuit using four different methodologies. QCA based Decoder circuit is implemented using coupled majority voter minority gate, 45 0 rotated cells, multilayer wire crossings and five input Majority Voter gate. Comparat...

A simple model quantum dot cell containing two electrons is analyzed as a candidate for quantum cellular automata implementations. The cell has eigenstates whose charge density is strongly aligned along one of two directions. In the presence of the electrostatic perturbation due to a neighboring cell, the ground state is nearly completely aligned (polarized) in one direction only. The polarizat...

We discuss the fundamental limits of computing using a new paradigm for quantum computation, cellular automata composed of arrays of Coulombically coupled quantum dot molecules, which we term quantum cellular automata (QCA). Any logical or arithmetic operation can be performed in this scheme. QCA’s provide a valuable concrete example of quantum computation in which a number of fundamental issue...

We discuss a novel nano-electronic computing paradigm in which cells composed of interacting quantum dots are employed in a locally-interconnected architecture. We develop a network-theoretic description in terms of appropriate local state variables in each cell.
