Quantum Physics Online  (version française)
est un ensemble d'applets Java interactives illustrant divers aspects de la physique quantique à l'aide de simulations et d'animations. C'est l'un des éléments d'un projet entrepris par Jean-Louis Basdevant, Jean Dalibard et Manuel Joffre en vue de développer un cours de physique quantique interactif, enseigné à l'Ecole Polytechnique.

The discovery that quantum physics allows fundamentally new modes of information processing has required the existing theories of computation (Turing), information (Shannon) and cryptography to be superseded by their quantum generalisations. The Centre for Quantum Computation, based at the University of Oxford, conducts theoretical and experimental research into all aspects of quantum information processing, and into the implications of the quantum theory of computation for physics itself.

QUIC is a collaboration of 5 groups at 3 universities, undertaking experimental, theoretical, and modelling investigations into quantum computing. The long range goal of this program of research is to realize a totally new class of computing engine --The Quantum Computer. It will directly employ the principles of quantum mathematics to perform, in a massively parallel fashion, calculations that are infeasible on today's computers.

JAVA

SGI Java Gallery  - Quantum Mechanical Scattering...
This JAVA applet integrates the Schrödinger wave equation. The wave funcition Psi(x,t) is initially a guassian wave packet moving to the right. The probability density p(x,t) = |Psi(x,t)|^2 is shown in black. The real and imaginary parts of Psi(x,t) are shown in blue and green. The potential energy function v(x) is shown in red.

A Procedural Formalism  for Quantum Computing
Bernhard Ömer - QCL is a hight level, architecture independent programming language for quantum computers, with a syntax derived from classical procedural languages like C or Pascal. This allows for the complete implementation and simulation of quantum algorithms (including classical components) in one consistent formalism.

Is there any hope for quantum computing to challenge the Turing barrier, i.e. to solve an undecidable problem, to compute an uncomputable function?

TUTORIELS - TUTORIALS - TUTORS

Samuel L. Braunstein. In this paper we give a tutorial on how quantum mechanics can be used to improve computation. Our challenge: solving an exponentially difficult problem for a conventional computer---that of factoring a large number.

QDD is a C++ library which provides a relatively intuitive set of quantum computing constructs within the context of the C++ programming environment. QDD is unique in that the its emulation of quantum computing is based upon a Binary Decision Diagram (BDD) representation of the quantum state.

HISTORIQUES - HISTORY

N 1999, legendary theoretical physicist Hans Bethe delivered three lectures on quantum theory to his neighbors at the Kendal of Ithaca retirement community (near Cornell University). Given by Professor Bethe at age 93, the lectures are presented here as QuickTime videos synchronized with slides of his talking points and archival material.
