### General

A Bluesci article by Peter Mattsson about Quantum Mechanics, Einstein and the EPR paradox

An introduction to the exploitation of quantum mechanics for perfectly secure communication. By Artur Ekert.

Cryptography can help with problems of trust. Instead of trusting other people involved, you need only check that the code does what it's supposed to do, and this can (sometimes) be proved.

An introduction to the phenomenon of quantum entanglement, which quantum computers would exploit to achieve their superiority over ordinary 'classical' computers. By Leah Henderson and Vlatko Vedral

A brief overview of the evolution of computing toward the "nanometre" scale where quantum mechanics may be exploited. By Simon Benjamin and Artur Ekert.

A short introduction to quantum information, including "teleportation". By David Deutsch and Artur Ekert.

### Basic Science

A short introduction to quantum computation by A. Barenco, A.Ekert, A. Sanpera and C.Machiavello from La Recherche, November 1996.

### Undergraduate Level

Lectures on Quantum Computation, Les Houches summer school 1999, by Artur Ekert, Patrick Hayden and Hitoshi Inamori (lecture notes, Postscript file)

A popular article about the reduction of communication complexity with the nonlocal correlations of quantum mechanics. By Andrew Steane and Wim van Dam.

An introduction to the principle of correcting quantum information without direct measurement (and consequent wavefunction collapse). By Andrew Steane

An introduction to why quantum computers would 'crack' some traditional cryptographic protocols. By Artur Ekert.

### Research Articles

Quantum cryptography could well be the first application of quantum mechanics at the individual quanta level. The very fast progress in both theory and experiments over the recent years are reviewed, with emphasis on open questions and technological issues.
