INTRODUCTION
The history of computer technology has involved a sequence of changes ZT\ one type of physical realization to another from gears to relays to valves to 3nsistors to integrated circuits and so on. Today's advanced lithographic *r-:hniques can squeeze fraction of micron wide logic gates and wires onto the s^face of silicon chips. Soon they will yield even smaller parts and inevitably each a point where logic gates are so small that they are made out of only a -^ndful of atoms; i.e. the size of the logic gates ....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

Abstract
In their article, Is the Brain a Quantum Computer,? Litt, Eliasmith, Kroon, Weinstein, and Thagard (2006) criticize the Penrose Hameroff Orch OR quantum computational model of consciousness, arguing instead for neurocomputation as an explanation for mental phenomena. Here I clarify and defend Orch OR, show how Orch OR and neurocomputation are compatible, and question whether neurocomputation alone can physiologically account for coherent gamma synchrony EEG, a candidate for the neural correlate of consciousness. Orch OR is based on ....etc

A THEORETICAL APPROACH TO MOLECULAR LEVEL QUANTUM COMPUTING
ABSTRACT:
In this paper we are extending the boundaries of quantum registers which forms the basis for future quantum computing. The atomic excitation and relaxation paves the way for replacing the old conventional bits by qubits. Our paper elaborates the idea of implementing the molecular transistors without affecting molecular coherent property, which will be a pathway to the quantum computer castle, using nitrogen induced diamond as a temporary RAM. The experi ....etc

net security with quantum cryptology

Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. The best known example of quantum cryptography is quantum key distribution which offers an information-theoretically secure solution to the key exchange problem. Currently used popular public-key encryption and signature schemes (e.g., RSA and ElGamal) can be broken by quantum adversaries. The advantage of quantum cryptography lies in the fact that it allows the completion of various cryptographic ....etc

Introduction
In recent past reversible computing has emerged as a promising technology having applica tions in low power CMOS , nanotechnology , optical computing , DNA computing , quantum computing etc. To establish the relevance of reversible and quantum computing it seems appropriate to note that the VLSI industry is moving at high speed towards minia turization. With miniaturization it faces two issues: i) A considerable amount of energy gets dissipated in VLSI circuits and ii) the size of t ....etc

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.

INTRODUCTION
Indium antimonide (InSb) shows great promise as an ultra-fast, very low power digital logic technology as it has t he highest electron mobility and saturation velocity of any known semiconductor .This performance can be accessed at room temperature using Extractive (minority carrier exclusion and extraction) technology, which mitigates the effect of the narrow band-gap on device leakage and breakdown. This was earlier
demonstrated in a MISFET device, using an InSb device layer on an ....etc
