A New QCA Architecture for the Future of Nano-Scale Computing

Hook IV L.R., Lee S-C, University of Oklahoma, US

By the time CMOS reaches its physical scaling limits in the next several years, computing will have very likely evolved to meet the demands imposed with increases in application complexity and the processing of enormous [...]

Implementation of Comparison Function Using Quantum-Dot Cellular Automata

Wagh M.D., Sun Y., Annampedu V., Lehigh University, US

Quantum-Dot cellular automata (QCA) architectures represent the future of computing. But it can only implement an inverter and a three input majority gate directly. Consequently very few QCA architectures are available in literature. By fixing [...]

Bayesian Modeling of Quantum-Dot Cellular Automata Circuits

Bhanja S., Srivastava S.N., University of South Florida, US

The goal of this work is to develop a fast, Bayesian Probabilistic Computing model [1], [2] that exploits the induced causality of clocking to arrive at a model with the minimum possible complexity. The probabilities [...]

RAM Design Using Quantum-Dot Cellular Automata

Walus K., Vetteth A., Jullien G.A., Dimitrov V.S., ATIPS Laboratory, CA

One of the most novel and powerful emerging nanotechnologies is quantum computing. This paper proposes a design for a parallel random-access memory (RAM) using Quantum-Dot Cellular Automata (QCA). QCA has the potential of becoming the [...]
