Design of an Efficient Multilayer Arithmetic Logic Unit in Quantum-Dot Cellular Automata (QCA)

IEEE Transactions on Circuits and Systems II: Express Briefs, 2019
Quantum-dot cellular automata (QCA) is a new nano-scale technology that due to making significant improvements in the design of electronic circuits can be considered as an appropriate alternative to CMOS technology. The arithmetic logic unit (ALU) is a fundamental component of the central processing unit to carry out the arithmetic and logical ...

Efficient Simulation of Correlated Dynamics in Quantum-Dot Cellular Automata (QCA)

IEEE Nanotechnology Magazine, 2014
Many simulations of quantum-dot cellular automata (QCA) rely upon the so-called intercellular Hartree approximation (ICHA), which neglects the possibility of entanglement between cells. While the ICHA is useful for solving many QCA circuits due to its relative simplicity and computational efficiency, its many shortcomings make it prohibitive in ...

Quantum-Dot Cellular Automata (QCA) circuit partitioning

Proceedings of the 41st annual Design Automation Conference, 2004
This paper presents the Quantum-Dot Cellular Automata (QCA) physical design problem, in the context of the VLSI physical design problem. The problem is divided into three subproblems: partitioning, placement, and routing of QCA circuits. This paper presents an ILP formulation and heuristic solution to the partitioning problem, and compares the two sets

Sequential circuit design using Quantum-dot Cellular Automata (QCA)

2012 IEEE International Conference on Circuits and Systems (ICCAS), 2012
As the size of CMOS transistors keep shrinking, it will eventually hit its limitation. Hence, an alternative device has to be discovered to continually improve the development of electronics devices. Quantum-dot cellular automata (QCA), is a potential device that can be used to implement digital circuits.

Simple 4-Bit Processor Based On Quantum-Dot Cellular Automata (QCA)

2005 IEEE International Conference on Application-Specific Systems, Architecture Processors (ASAP'05), 2006
We describe the design and layout of a simple 4-bit processor based on quantum dot cellular automata (QCA) using the QCADesigner design tool. The processor design is based on an accumulator architecture which reduces the required hardware complexity and allows for reasonable simulation times.
