Measurement-Based Conference

The fact that you can perform unitary quantum evolutions using simple (adaptive) measurements is, to a physicist, an unexpected result. Indeed, it could be that there is no unitary evolution in the universe, only measurements! If you’re interested in measurement based quantum computing, you might be interested in conference advertised below:

International Workshop on Measurement-based Quantum Computation (MBQC07)
St. John’s College, Oxford
18 – 21 March 2007
http://www.qunat.org/workshop/
Measurement-based quantum computing (MBQC) is an active and rapidly growing area of research. The formalism of graph states (or cluster states) has proven to be a powerful way of describing the essential entanglement resources needed to perform quantum information processing tasks. Initially conceived for systems such as optical lattices and linear optical computing, this theory is now shaping the latest experimental proposals across the full spectrum of QIP technologies. A key theme of this workshop will be to foster dialog between theoreticians involved in MBQC and the experimentalists who are positioned to embrace and implement the new ideas.
Registration is open until November 30th and the number of participants will be limited to 50.

SFI Postdocs

This is a bit late being posted, but the Santa Fe Institute is running their postdoc search this year. SFI has always had a running interesting the border between physics and computer science and was even crazy enough to hire a crazy theorist like me as a postdoc. Oh, how I miss those green chiles. Here is the information for the positions, which I highly recommend quantum computing people to consider as an option. Plus you’ll get to live in New Mexico and eat lots of awesome New Mexican food and go skiing at the ever awesome Taos ski area (not to mention that the UNM and Los Alamos quantum computing groups are but a short drive away):

POSTDOCTORAL FELLOWSHIP OPPORTUNITIES
The Santa Fe Institute (SFI) anticipates offering several Postdoctoral Fellowships to begin in September 2007.
The Postdoctoral Fellowship program provides up to three years of support for independent research at SFI. Postdoctoral Fellows are encouraged to engage research questions of their own design, and to form collaborations with members of the faculty, other SFI postdocs, and researchers from around the world. Fellows pursue research that lies at the boundaries of the traditional academic disciplines, and that creates new fields of inquiry.
In addition to salary, health benefits, and retirement contributions, Fellows have access to funds to support travel to meetings, to visit collaborators at other institutions, and to bring collaborators to visit SFI. Fellows are encouraged to participate in all SFI activities, to invite speakers for the colloquium series, and to organize workshops and working groups.
Research at SFI is integrative, and there are no formal programs or departments. Individual research projects draw input from a variety of fields, including biology, chemistry, computer science, physics, mathematics, economics, sociology, anthropology, and political science. We welcome applications from any of these fields, as well as others not listed here. Descriptions of the research interests of the faculty and current Postdoctoral Fellows can be found at http://www.santafe.edu/research/researchers.php. Most research at SFI focuses on theoretical and computational approaches, although applicants whose research includes an experimental or data-collection component in collaboration with off-site colleagues are also encouraged to apply.
Candidates should have a Ph.D. (or expect to receive one by September 2007), a strong academic record, and a proven ability to work independently. We are particularly favorable toward applicants with an interest in trans-disciplinary interactions and collaboration, and who have demonstrated the potential to think outside traditional paradigms.
Applications are welcome from candidates in any country. Women and minorities are especially encouraged to apply. Successful foreign applicants must acquire an acceptable visa (usually a J-1) as a condition of employment
TO APPLY: Please view the full position announcement and application instructions at http://www.santafe.edu/education/postdocinst07.php. For full consideration, please submit all application materials, including three letters of recommendation, by November 15, 2006. For further information, please e-mail postdocinfo[at]santafe.edu.

Where In the World Is David San Diego?

Visiting the Rambling Wreck from Georgia Tech! Just in time because it was freeeezing in Seattle (ice on the windshield…which means snow in the hills soon!)

When Physics and Computer Science Collide!
Our world, at its very base, appears to be a cauldron of indeterminism. Not only does quantum theory tell us that we can at best predict the probabilities of different events, but every system in nature is an open system which interacts with its surroundings to produce uncertainties in the state of the system. How, then, in such an uncertain world, is it possible to produce machines which operate with virtual certainty? This question is at the heart of defining what is and what is not a computer. In this talk I will discuss how we approach this problem in the field of quantum computing through what is known as the theory of fault-tolerant quantum computing. This will take us on a broad tour of some of the most exciting ideas occuring where physics and computer science collide.

Zotero Zero Until Arxivero

No arXiv support yet, but a cool firefox reference organizer tool to keep an eye on Zotero. Without arxiv support its pretty much useless to me right now, but playing around with it for other sites makes me think it would be extremely valuable.

Quantum Percent Sign?

Okay, so when we talk about classical systems, our description of the configuration of the different states is given by a probability. So I might say my bit is a mixture of 50% 0 and 50% 1. Now when we move to quantum theory we no longer have probabilities but instead have complex numbers. But what symbol am I supposed to use for this? My state is a mixture of 1/sqrt(2) q% 0 and 1/sqrt{2} q% 1? Mabye we should invent a new symbol which is the % sign but with the slash the other direction? Or turn those 0s in the % sign into “q”s?

QIP 2007 Deadlines Approaching

Michel Nielsen passes along and email detailing the fact that the deadlines for QIP 2007, to be held in Brisbane, Australia, are fast approaching:

QIP 2007
The tenth QIP (Quantum Information Processing) Workshop is to be held in
Brisbane, Australia, from January 30 through February 3, 2007. QIP covers
theoretical aspects of quantum information science, including quantum
computing, quantum cryptography, and quantum information theory.
The deadline for abstract submission for contributed talks (long and
short) and for posters is 4 November, 2006.
The deadline for early bird registration is 24 November, 2006.
Some partial support available for students and postdocs will be available
(see the website).
Full details are available at the workshop website:
http://qipworkshop.org/
Links to past QIP workshops (including programs) are available at the
website. Note that this year’s program will follow a similar format to
QIP 2006, with approximately 10 invited talks, and 30 contributed talks.
Hope to see you in Brisbane in 2007!

I have to decide whether I’m going to be able to make it this year as I’m teaching Data Structures next term. Two years in a row missing QIP sounds really bad to me.

Siskiyou Daily News Police Reports

I grew up in a small town. Whenever I go home, one of the first things I do is turn to the Police Department report in the local newspaper. Why? To see if my friends have ended up in jail? Nope. For gems like this

Possible dead male in wheelchair. Emergency personnel were dispatched. Officier advised, subject was fine, wheelchair was dead. Wheelchair and subject was transported to his residence.

or, how about this,

Report of a dog causing a traffic problem in the area. Officer arrived and located the dog. After a game of fetch the dog was loaded into the car taken to the kennels.

or, maybe this

Report of a man carrying dead turkey down Main Street. Turkey determined to be recent kill and hunting season open.

Green Eggs and Green Bacon

Apparently I’m running for the public regulation commission in Albuquerque, NM (spotted by UNM quantum scientists eating at the delicious El Patio, those lucky bastards.)
