Quantum computers

A community portal about Quantum computers with blogs, videos, and photos. According to Wikipedia.org: A quantum computer is any device for computation that makes direct use of distinctively quantum mechanical phenomena, such as superposition and entanglement, to perform operations on data. In a classical computer, the amount of data is measured by bits; in a quantum computer, the data is measured by qubits. The basic principle of quantum computation is that the quantum properties of particles can be used to represent and structure data, and that quantum mechanisms can be devised and built to perform operations with these data.

Future directions in computing

Written by

From: special-sarfunshafi.blogspot.com

Future directions in computing Silicon electronics are a staple of the computing industry, but researchers are now exploring other techniques to deliver powerful computers. A quantum computer is a theoretical device that would make use of the properties of quantum mechanics, the realm of physics that deals with energy and matter at atomic scales. In a quantum computer data is not processed by electrons passing through transistors, as is the case in today's computers, but by caged atoms known as quantum bits or Qubits. "It is a new paradigm for computation," said Professor Artur Ekert of the University of Oxford. "It's doing computation differently." ... Read Full Story

Promise of a Quantum Internet

Entangled Web: The optical components on this lab bench, such as mirrors and filters, allow researchers in Prem Kumar’s lab at Northwestern University to direct and manipulate light. In Kumar’s most recent work, he has created a quantum logic gate within an optical fiber; such gates could eventually enable networks of quantum computers. Credit: Prem Kumar The promise of quantum computers is tantalizingly great: near-instantaneous problem solving, and perfectly secure data transmission. For the most part, however, small-scale demonstrations of quantum computation remain isolated in labs throughout the world. Now, Prem Kumar , a professor of electrical engineering and computer science at Northwestern University, ... Read Full Story

This thing will change the way you check your email....basically youll be able to access the intermatrix about 10 minutes into the future - then return your email that has yet to be sent yet....and then something about a cat in a box being alive at the same time. http://www.engadget.com/2007/02/08/quantum-computer-to-debut-next-tuesday/ Read Full Story

Ebook Quantum Computation and Quantum Information

From: www.acrobatplanet.com

Science offers the boldest metaphysics of the age. It is a thoroughly human construct, driven by the faith that if we dream, press to discover, explain, and dream again, thereby plunging repeatedly into new terrain, the world will somehow come clearer and we will grasp the true strangeness of the universe. And the strangeness will all prove to be connected, and make sense. - Edward O. Wilson Information is physical. - Rolf Landauer What are the fundamental concepts of quantum computation and quantum information? How did these concepts develop? To what uses may they be put? How will they be presented in this book? ... Read Full Story

Breakthrough: Computer Memory Stored in the Nucleus of an Atom

Written by

jdrucker on

From: techsciencereview.com

An international team of scientists recently performed the ultimate miniaturization of computer memory: storing information at the nucleus of an atom. The breakthrough is a key step in bringing to life quantum computers, devices based on the theory of quantum mechanics. In the quantum world, objects such as atoms can exist simultaneously in multiple states–that is, they could literally be in two places at once, or possess a number of other seemingly mutually exclusive properties. Quantum computing is seen as a holy grail of computing because each individual piece of information, or ‘bit’, can have more than one value at once. A bit is ... Read Full Story
