Abstract:
We discuss novel nanoelectronic architecture paradigms based on cells composed of coupled quantum-dots. Boolean logic functions may be implemented in specific arrays of cells representing binary information, the so-called Quantum-Dot Cellular Automata (QCA). Cells may also be viewed as carrying analog information and we outline a network-theoretic description of such Quantum-Dot Nonlinear Networks (Q-CNN). In addition, we discuss possible realizations of these structures in a variety of semiconductor systems (including GaAs/AlGaAs, Si/SiGe, and Si/SiO 2), rings of metallic tunnel junctions, an

We discuss novel nanoelectronic architecture paradigms based on cells composed of coupled quantum-dots. These ideas of a transistor-less approach represent a radical departure from conventional technology. We utilize a strategy which exploits the physical interactions between quantum-dots arranged in suitably designed cellular arrays.

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

Field-Coupled nanocomputing (FCN) paradigms offer fundamentally new approaches for digital computing without involving current transistors. Such paradigms perform computations using local field interactions between nanoscale building blocks which are organized with purposes. Among several FCN paradigms currently under active investigation, the Molecular Quantum-dot Cellular Automata (MQCA) is found to be the most promising and its unique features make it attractive as a candidate for post-CMOS nanocomputing.

Quantum-dot cellular automata is an emerging technology for digital computation that follows the More than Moore trends and aims to the simultaneous reduction of both device size and power consumption. In particular, the basic QCA device is a cell made of dots and in which a bunch of free charges are allowed to move without leaving the cell itself. 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.

Molecular quantum-dot cellular automaton (QCA) offers an alternative paradigm for computing at the nano-scale. Such Q C A circuits require an external clock, which can be generated using a network of submerged electrodes, to synchronize information flow, and provide the required power to drive the computation. In this thesis, the effect of electrode separation and applied potential on the likelihood of different Q C A cell states of molecular cells located above and in between two adjacent electrodes is analysed.

Abstract:
Quantum-Dot Cellular Automata (QCA) is being investigated as a possible alternative for encoding and processing binary information in an attempt to realize dramatic improvements in device density and processing speed over conventional CMOS design. The binary information is encoded in the locations of two excess electrons in a system of four quantum dots. The dots are arranged with each on a corner of a square, and electrons are able to quantum-mechanically tunnel between dots. Each set of four dots and two excess electrons constitutes a QCA cell.

Abstract:
To have a useful QCA device it is first necessary to study how to control data flow in a device, then study how temperature and manufacturing defects will affect the proper output of the device. Theoretically a "quantum wire" of perfectly aligned QCA cells at zero Kelvin temperature has been examined. However, QCA processors will not be operating at a temperature of zero Kelvin and inherently the manufacturing process will introduce defects into the system. Many different types of defects could occur at the device level and the individual cell level, both kinds of defects should be examined. D
