To be held in Waterloo, Canada; hosted by the Perimeter Institute for Theoretical Physics and the Institute for Quantum Computing.
January 15 - 19, 2004
Quantum information processing is the recasting of computer science in a quantum mechanical framework. It tries to improve on classical computers and classical complexity bounds by making use of quantum mechanical phenomena. After Peter Shor's 1994 discovery of efficient quantum algorithms for factoring and the discrete log (threatening current "classical" cryptography), the field has grown explosively and is now one of the most active subfields of both computer science and physics. QIP 2004 is the seventh workshop on quantum computing, quantum cryptography, and quantum information theory in the tradition of AQIP 98 in Aarhus, AQIP 99 in Chicago, QIP 2000 in Montreal, QIP 2001 at the CWI in Amsterdam, QIP 2002 at IBM in Yorktown Heights, and QIP 2003 at MSRI, Berkeley. The conference will run from Thursday 15 January until Monday 19 January. It will consist of various invited talks, a display of posters, and an open session.
Co-chairs: Michele Mosca (IQC & PI), Daniel Gottesman (PI) and Ashwin Nayak (IQC & PI).
Steering Committee: Dorit Aharonov, Charles Bennett, Harry Buhrman, Isaac Chuang, David DiVincenzo, Miklos Santha, Umesh Vazirani, John Watrous.

Here's a well-informed, accessible article on recent developments in quantum computing (namely, the Innsbruck experiment implementing the Deutsch-Josza algorithm). The author, Chris Wenham, wasn't able to sell it to a commercial publication, perhaps because it was too informative?
Tuesday, January 07, 2003
This one from the Edge 2003 World Question Center:
"By their potential power, quantum computers pose a significant threat to the security not only of classified encoded material, but to the security of most commercial transactions, in particular those that take place electronically. Despite the clear application of quantum computation to problems of national security, your security agencies have elected to pursue the majority of their research on quantum computers by open competition for public funds, under the stipulation that the results of the research be published and made available to all.
This is a wise course."
Science is public knowledge. But science is not the only field where openness is important. The security failures of 9/11 were caused not by too little, but by too much secrecy. And the discussions that form public policy should be public.
I know that other advisors are offering you conflicting advice: keep your cards close to your chest—don't let our enemies (or our allies) benefit from our hard-earned knowledge. Don't listen to them. Science isn't poker: it only works when the cards are dealt face up. Don't go down in history as the Texan who closed the scientific frontier.
Artur Ekert and Ignacio Cirac:
Following the editions of Benasque 1998 and 2000 we are organizing a workshop on quantum information in the summer of 2003. This is to invite you to apply using the electronic form that you can find at the website specified below. We would very much appreciate it if you could apply as soon as possible and not later than March 2003. The number of participants at the Benasque Centre at a given time is limited to about 50 and although we will do our best to accommodate most of the applicants, in some cases we may be unable to find suitable time slots for all of them, i.e. we cannot guarantee acceptance. On the other hand, participants staying for the full period will be offered an allowance of about 400 Euro. We do hope to see you in Benasque next year!
Title: Quantum Information.
Venue: Benasque in the Spanish Pyrenees.
Date: The 3 week period 22 June -- 11 July 2003.
