Reversible computation with quantum-dot cellular automata (QCA)

Proceedings of the 2nd conference on Computing frontiers, 2005
Quantum-dot cellular automata (QCA) is a strategy in which binary data is represented by charge configuration within a multi-dot cell. Data is transmitted to nearest neighbors by the Coulombic interaction. An electric field acts as a clock and imposes directionality on circuits. We have explored the connection between logical reversibility and physical

An efficient Quantum-Dot Cellular Automata adder

2011 Design, Automation & Test in Europe, 2011
This 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), 2018
Quantum-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.

General floorplan for reversible quantum-dot cellular automata

Proceedings of the 4th international conference on Computing frontiers, 2007
This 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.

Towards Approximate Computing with Quantum-Dot Cellular Automata

Journal of Low Power Electronics, 2017
In this paper, we inspect the approximate computing concept in quantum-dot cellular automata (QCA) as one of the most promising emerging nanoelectronic paradigms for replacing CMOS technology. Many applications can tolerate errors and imprecision of digital systems, so approximate computing is widely used in such cases.

The Development of Quantum-Dot Cellular Automata

2014
Quantum-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.

Evaluating the Impact of Interconnections in Quantum-Dot Cellular Automata

2018 21st Euromicro Conference on Digital System Design (DSD), 2018
Quantum-Dot Cellular Automata (QCA) are an emerging nanotechnology with remarkable performance and energy efficiency. Computation and information transfer in QCA is based on field forces rather than electric currents. As a consequence, new strategies are required for design automation approaches in order to cope with the arising challenges.

Quantum-dot cellular automata serial decimal subtractors

Automatic Control and Computer Sciences, 2012
Two designs for quantum-dot cellular automata serial decimal subtractors are proposed for a nanocomputer. The 5-bit Johnson-Mobius code is used to encode decimal digits. The first design leverages the complement addition method, while the second design uses the direct subtraction method. The proposed subtractors are compared to the existing quantum-dot
