Definition
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.

Grover's Algorithm A Fast Search Method Using Quantum Parallelism

Genetic Algorithms provide an effective way of searching complex fitness landscapes. Grover’s Algorithm is a quantum algorithm used to search through a database of values and determine where a particular target value is stored. It does so by using quantum parallelism so that it is more efficient than its classical counter- parts. The way the algorithm was originally designed allows for findi ....etc

Abstract
As technology trends push future microprocessors to- ward chip multiprocessor designs, operating system net- work stacks must be parallelized in order to keep pace with improvements in network bandwidth. There are two competing strategies for stack parallelization. Message- parallel network stacks use concurrent threads to carry out network operations on independent messages (usu- ally packets), whereas connection-parallel stacks map operations to gro ....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.

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.

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

[:=Read Full Message Here=:]

Answer:.Inter-query parallelism results from the ability to execute multiple queries at the same time while intra-query parallelism is achieved by breaking up a single query into a number of subqueries each of which is executed at a different site, accessing a different part of the distributed database.
If the user access to the distributed database consisted only of querying (i.e.,
read-only access), then provision of inter-query and intra-query parallelism would
imply that as much of the database as possible should be replicated. Howeve ....etc
