Quantiki

IBM bets big on spintronics, new type of memory which it says will deliver terabyte MP3 players.

Researchers in the UK have taken a small but important step towards the creation of practical quantum computers by creating the first logic gates on a silicon chip that can process individual photons. The chip, which measures several millimetres across, reproduces an earlier version of the gate that occupied several square metres of space on an optical bench.

A new study hints that black holes might not be as good at keeping secrets as researchers have long thought. Recently [http://www.cs.mcgill.ca/~patrick/ Patrick Hayden] and [http://www.theory.caltech.edu/~preskill/ John Preskill] have reexamined the time it would take for information to potentially escape from inside a black hole.

Slashdot has an article about the withdrawal of an article by Jonathan Oppenheim and co-authors from Physical Review Letters because they had asked for a rights agreement compatible with GFDL which Quantiki uses for its content.

The Canadian Quantum Information Summer School has become an annual Canadian tradition and welcomes students from all over the world. The Eighth installment aims to introduce the participants to quantum algorithms, quantum error correction, quantum information theory and quantum cryptography. They will also receive lectures on implementations, quantum complexity theory, nonlocality and some more recent developments in quantum algorithms, namely quantum walks.

The Summer School is being held at the Université de Montréal in Montreal, Quebec, Canada from June 9 to 13, 2008.

One of the problems plaguing classical communication is associated with what is known as the Byzantine agreement. In this problem, messages between three different parties are subject to faulty information. Quantum communication, though, has held the promise of solving this dilemma. But until now, it has been difficult to do so, even using entangled states.
