The Development of Quantum-Dot Cellular Automata
2014Quantum-dot cellular automata (QCA) is a paradigm for connecting nanoscale bistable devices to accomplish general-purpose computation. The idea has its origins in the technology of quantum dots, Coulomb blockade, and Landauer’s observations on digital devices and energy dissipation.

An efficient Quantum-Dot Cellular Automata adder
2011 Design, Automation & Test in Europe, 2011This paper presents a ripple-carry adder module that can serve as a basic component for Quantum Dot Automata arithmetic circuits. The main methodological design innovation over existing state of the art solutions was the adoption of so called minority gates in addition to the more traditional majority voters. Exploiting this widened basic block set, we

Exploration of the Synchronization Constraint in Quantum-dot Cellular Automata
2018 21st Euromicro Conference on Digital System Design (DSD), 2018Quantum-dot Cellular Automata (QCA) is a field-coupled nanotechnology which might enable design with high performance and extraordinary low energy dissipation. Infor-mation processing and flow in QCA is controlled by external clocks, which requires a proper synchronization already during circuit design phase.

An efficient FPGA implementation in quantum-dot cellular automata
2013 26th Symposium on Integrated Circuits and Systems Design (SBCCI), 2013This paper describes the complete implementation of an efficient FPGA in quantum-dot cellular automata (QCA). FPGAs are reconfigurable digital devices which are extensively used in a wide range of industry applications. QCA is a promising nanotechnology able to overcome the limits of current CMOS technology.

General floorplan for reversible quantum-dot cellular automata
Proceedings of the 4th international conference on Computing frontiers, 2007This paper presents the Collapsed Bennett Layout, a general purpose floorplan for reversible quantum-dot cellular automata (QCA) circuits. In order to exploit the full density and speed potential of emerging nanodevices, the principles of reversible computing need to be incorporated into the design of nanoscale circuits and systems.

Characterizing Quantum-Dot Cellular Automata
2014We undertake an in-depth numerical study of quantum-dot cellular automata (QCA), a beyond-CMOS computing paradigm which represents bits as bistable charge distributions in cells consisting of quantum dots. Using semi-realistic but material-independent mod- elling, we characterize the building blocks of QCA circuits in as detailed and unbiased a manner ...
