Abstract:
Quantum-dot cellular automata (QCA) is a low-power, non-von-Neumann, general-purpose paradigm for classical computing using transistor-free logic. Here, classical bits are encoded on the charge configuration of individual computing primitives known as “cells.” A cell is a system of quantum dots with a few mobile charges. Device switching occurs through quantum mechanical inter-dot charge tunneling, and devices are interconnected via the electrostatic field. QCA devices are implemented using arrays of QCA cells. A molecular implementation of QCA may support THz-scale clocking or better at room

This article describes the design of ultra-low-power multipliers on quantum dot cellular automata (QCA) nanotechnology, promising very dense circuits and high operating frequencies, using a single homogeneous layer of the basic cells. We construct structures without the earlier noise problems, verified by the QCA Designer coherence vector simulation. Our results show that the wiring overhead of the arithmetic circuits grows quadratically with the operand word length, and our pipelined array multiplier has linearly better performance-area efficiency than the previously proposed serial-parallel

Further downscaling of CMOS technology becomes challenging as it faces limitation of feature size reduction. Quantum-dot cellular automata (QCA), a potential alternative to CMOS, promises efficient digital design at nanoscale. Investigations on the reduction of QCA primitives (majority gates and inverters) for various adders are limited, and very few designs exist for reference. As a result, design of adders under QCA framework is gaining its importance in recent research.

The molecular Field-Coupled Nanocomputing (FCN) is a promising implementation of the Quantum-dot Cellular Automata (QCA) paradigm for future low-power digital electronics. However, most of the literature assumes all the QCA devices as possible molecular FCN devices, ignoring the molecular physics. Indeed, the electrostatic molecular characteristics play a relevant role in the interaction and consequently influence the functioning of the circuits.

Depending on which dots the free charges occupy inside the cell (called also charge localization inside the cell) the binary information could be encoded and the interaction between nearby cells is performed by the electrostatic interaction.
