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.

The subject of quantum computing brings together ideas from classical information theory, computer science, and quantum physics. This document aims to summarize not just quantum computing, but the whole subject of quantum information theory. It turns out that information theory and quantum mechanics fit together very well. In order to explain their relationship, the paper begins with an introduction to classical information theory .The principles of quantum mechanics are then outlined.

The infrastructure of the Information Age has to date relied upon advances in microelectronics to produce integrated circuits that continually become smaller, better, and less expensive. The emergence of photonics, where light rather than electricity is manipulated, is posed to further advance the Information Age. Central to the photonic revolution is the development of miniature light sources such as the Quantum dots(QDs).

Today, Quantum Dots manufacturing has been established to serve new datacom and telecom markets. Recent progress in mic ....etc

Since it first appeared on the cover of Nature in February 2000, the quantum mirage? has featured on posters, calendars, websites and the covers of various books and magazines. The image ? which was obtained using a scanning tunnelling microscope ? shows the electronic wavefunctions inside an elliptical ?quantum corral? made of cobalt atoms on a copper surface. It was created by Hari Manoharan, Christopher Lutz and Don Eigler of the IBM Almaden Research Center in California. In 1990, working with Erhard Schweizer, Eiger spelt out the letters ?I ....etc

The history of computer technology has involved a sequence of changes from one type of physical realisation to another --- from gears to relays to valves to transistors to integrated circuits and so on. Today's advanced lithographic techniques can squeeze fraction of micron wide logic gates and wires onto the surface of silicon chips. Soon they will yield even smaller parts and inevitably reach a point where logic gates are so small that they are made out of only a handful of atoms; i.e. the size of the logic gates become comparable ....etc

Quantum Mirage

ABSTRACT
Since it first appeared on the cover of Nature in February 2000, the quantum mirage” has featured on posters, calendars, websites and the covers of various books and magazines. The image – which was obtained using a scanning tunnelling microscope – shows the electronic wavefunctions inside an elliptical “quantum corral” made of cobalt atoms on a copper surface. It was created by Hari Manoharan, Christopher Lutz and Don Eigler of the IBM Almaden Research Center in California. In 19 ....etc

Quantum Mirage


INTRODUCTION
1.1 OVERVIEW
Today, an MP3 player that is smaller than a book of matchbox can hold four gigabytes of information – enough space to store about 750 to 1000 songs. When it comes to the capabilities, power, speed and energy efficiency that are capable of being packed into a cell phone or a laptop, a phenomenon called quantum mirage portends that the surface may have only been scratched so far. Essentially ....etc

Quantum cryptography is an effort to allow two users of a common communication channel to create a body of shared and secret information. This information, which generally takes the form of a random string of bits, can then be used as a conventional secret key for secure communication. It is useful to assume that the communicating parties initially share a small amount of secret information, which is used up and then renewed in the exchange process, but even without this assumption exchanges are possible.
