Definition

Quantum Dot Lasers can be considered as a quantum leap in the development of lasers. Quantum Dots improve basically the laser emissions. This property of Quantum Dots is well utilized for fiber optic communication, which is now the leading subject under research and development. Quantum Dots are thus very well used in applications fiber optic communication. The remaining major division of the field of quantum electronics deals with the interactions of coherent light with matter and again leads to a wide range of all-optical and op ....etc

ABSTRACT
Quantum Dots(QDs) are small conductive regions in a semiconductor, containing a number of charge carriers(from one to thousand) that occupy well defined discrete quantum states. They have typical dimensions between nanometers to a few microns .When the space at any side, around a material shrinks to 100 , quantisation of the energy levels at the reduced side will occur. In quantum dots electrons are confined in all directions to a volume in space with dimensions on the order of their de Broglie wave length, ie, the ....etc

Applications of Majority Gates with Quantum-Dot Cellular Automata(QCA)

ABSTRACT
Majority gate-based logic is not normally explored with standard CMOS technologies,primarily because of the hardware inefficiencies in creating majority gates.As a result,not much effort has been made towards the optimization of circuits based on majority gates.We are exploring one particular emerging technology,quantum-dot cellular automata(QCA),in which the majority gate is the fundamental logic primitive.One of its main application is a simple and in ....etc

theory of automata by puntambekar pdf free download

Automata Theory is a branch of computer science that deals with designing abstract self-propelled computing devices that follow a predetermined sequence of operations automatically. An automaton with a finite number of states is called a Finite Automaton. This is a brief and concise tutorial that introduces the fundamental concepts of Finite Automata, Regular Languages, and Pushdown Automata before moving onto Turing machines and Decidability.

Deterministic Finite State Automata

One-way, infinite tape, broken into cells
One-way, read-only tape head.
Finite control, I.e., a program, containing the position of the read head, current symbol being scanned, and the current state.
A string is placed on the tape, read head is positioned at the left end, and the DFA will read the string one symbol at a time until all symbols have been read. The DFA will then either accept or reject.

Quantum Wells, Quantum Wire, and Quantum Dots

I'd like to explore the material known as Wellstone. There are some interesting aspects to this material, and it is written about in Hacking Matter by Will McCarthy. It is not necessarily nanotechnology, so much as it is quantum level materials and bio-molecular control over nano sized or meso-sized particles.
We will return to the world of Nanotechnology and DNA computing shortly, for now - let's talk about Wellstone.
