QIP 2012 videos!

The long awaited videos from QIP 2012 are now online.
Somewhat. If you see a video that you want that isn’t online, then tell the speaker to sign the release form! I’m looking at you Bravyi, Greiner, Landahl and Popescu! (And others.)
If you haven’t seen them before, then you should check out the talks by Haah (on 3-d local stabilizer codes) and Arad (on an improved 1-d area law).

Scott Aaronson wins Alan T. Waterman Award

The NSF just announced that our own Scott Aaronson has been named a co-recipient of this year’s prestigious Alan T. Waterman award! The award is granted to outstanding researchers under the age of 35 across any field of science or engineering which is supported by the NSF.
Not only is this great news for Scott, but a rising tide lifts all boats: the entire field of quantum computing benefits when our talented researchers get recognition for their achievements.
Congratulations to The Optimizer on this richly deserved award.

Quantum Information and Foundations at the APS March Meeting 2012

After John Preskill’s call for more quantum participation at the APS March Meeting, I couldn’t say no to a request for a blurb about quantum info and foundations! The following is a guest post by Giulio Chiribella.
Following up the previous post by John Preskill, I’d like draw your attention to the focus session “Quantum Information for Quantum Foundations” which will take place at the APS March Meeting 2012.
If you are interested in the conceptual and fundamental aspects of Quantum Information, this is the right session for you to come and present your work! The event promises to be lively and stimulating, and will be a great occasion to advertise your recent results.
On top of that, your participation will give an important support to foundational research.The foundational space at the March meeting is a great opportunity for our community.  But it is vital to keep this space alive, responding with a visible participation and presenting talks on the best of the foundational research in Quantum Information. This is not hard to do: Over the past few years there has been an enormous amount of progresses and a burst of new exciting results at the interface between Quantum Information and Foundations.  Also, we should not forget of the numerous results in Quantum Information that, even without being explicitly foundational, continue to shed a bright light on the operational features of Quantum Theory.   It is enough to have such a vibrant scientific landscape represented next March in Boston to make the foundational session memorable!
This year’s session will start with an invited talk by Valerio Scarani, who will summarize the main ideas and the latest developments on Information Causality. Valerio’s talk will be followed by a lineup of contributed talks, which hopefully would be as many and as lively as the talks of last year’s edition, organized by Chris Fuchs, which has been a very successful event.
To participate to the session, you can submit your abstract at the webpage http://www.aps.org/meetings/abstract/index.cfm. (don’t forget that the deadline for submissions is this Friday November 11th 2011!)
A last remark before concluding:  Chatting with colleagues sometimes I noticed that potential speakers are discouraged by the 12 minutes format, which seems too short to present all the relevant details. We should remind, however, that presenting details is not really the point here: The APS Meetings are huge events where the whole physics community meets to highlight advancements and to advertise new ideas across fields, not to address the specialists of one particular field.  The format of the March Meeting talks is designed to rapidly advertise new results, and if you discover that you would like to know more about one particular result…  well, during the meeting there is a lot of free time where you can interact directly (and more efficiently)  with the speaker about the details of her/his work.
So, let us take the event in the right spirit and make the foundational space at the March Meeting a real exciting forum for the exchange of new ideas!
Hope to see many of you in Boston!

QEC '11 Registration Deadline Extension

The registration and submission deadline for QEC ’11 has been extended by a week and is now open until November 7th.
You can register here: http://qserver.usc.edu/qec11/reg.html
It looks like a great conference… I wonder if the Ghost Pontiff will show up to give his invited talk?

Dial M for Matter

It was just recently announced that Institute for Quantum Information at Caltech will be adding an extra letter to its name. The former IQI will now be the Institute for Quantum Information and Matter, or IQIM. But it isn’t the name change that is of real significance, but rather the $12.6 million of funding over the next five years that comes with it!
In fact, the IQIM is an NSF funded Physics Frontier Center, which means the competition was stiff, to say the least. New PFCs are only funded by the NSF every three years, and are chosen based on “their potential for transformational advances in the most promising research areas at the intellectual frontiers of physics.”
In practice, the new center means that the Caltech quantum info effort will continue to grow and, importantly, it will better integrate and expand on experimental efforts there. It looks like an exciting new chapter for quantum information science at Caltech, even if the new name is harder to pronounce. Anyone who wants to become a part of it should check out the open postdoc positions that are now available at the IQIM.

Ig Nobels 2011

Yes, it’s that time of year again. The Ig Nobel Prize ceremony was held this evening at Harvard. My favorite is the winner of the Ig Nobel Peace Prize, which went to

Arturas Zuokas, the mayor of Vilnius, Lithuania, for demonstrating that the problem of illegally parked luxury cars can be solved by running them over with an armoured tank.

This could have plausibly gotten him an Ig Nobel in economics instead, since it’s all about incentives. The video is priceless:

As of right now, the list of winners is still not up at the home page for the Annals of Improbable Research. That link should start working shortly, but until then I found this article from the BBC which gives complete coverage of the event. Enjoy!
Of course, this means that we will know the winners of the “real” Nobels soon enough. Put your best guess for the Physics prize in the comments.

Theoretical Physics StackExchange

Correction added 4 Oct: The site is in public beta now.
Correction added 27 Sep: At least for now, the site is in a closed beta, restricted to the people who initially committed to using it. Once that changes, we’ll let you know here.
There is a new Q&A website for theoretical physics started by our own Joe Fitzsimons. Go check it out!
http://theoreticalphysics.stackexchange.com/
The site will remain in beta for 60 to 90 days, at which time it will become a permanent StackExchange website…if there is enough activity during the 60-90 days! So go check out the website, ask and answer vexing quantum questions, and witness the power of crowdsourcing.

Two kilopontiffs, and Pontiff++

This post is the 2000th post here at the Quantum Pontiff!
And it seems that the former proprietor of this blog just couldn’t stop blogging… so go check out his new blog, Pontiff++.

Q-circuit v2.0

Many readers are familiar with the LaTeX package called Q-circuit that I coauthored with Bryan Eastin. If you aren’t familiar with it, it is a set of macros that helps make typesetting quantum circuits easy, efficient and (reasonably) intuitive.  The results are quite beautiful, if I do say so myself, as can be seen in the picture to the left.
In the past year Bryan and I began getting emails from Q-circuit users who were experiencing some bugs. It turns out that the issue was usually an incompatibility between Q-circuit v1.2 and Xy-pic v3.8, an update to a package that Q-circuit relies on heavily.
Thanks to the user feedback and some support from the authors of Xy-pic, we were able to stamp out the bugs. (Probably… no guarantees!) Thus I present to you the latest version of Q-circuit!
Download Q-circuit v2.0
There is more info on the Q-circuit website, where you will find the tutorial, some examples, and you can also enjoy the painfully retro green-on-black motif. (Let the haters hate… I like it.) A few additional technical details:

  1. Nothing has been added to the new version.  It is as near as possible to the old version while still functioning with Xy-pic version 3.8.x.
  2. The old version of Q-circuit works better with Xy-pic version 3.7. (When using Xy-pic 3.7, Q-circuit 2.0 makes PDFs with slightly pixelated curves.)
  3. The arXiv is still using Xy-pic 3.7 and they don’t know when they’ll update to 3.8.

Finally, a big thank you to my coauthor Bryan for putting in so much hard work to make Q-circuit a success!

Habemus Papam(s)!

fumata bianca
The conclave has reached an agreement. The new quantum papal dynasty will be a triumvirate consisting of:

  • Charlie Bennett
  • Aram Harrow
  • Steve Flammia

For those of you concerned about having three pontiffs at the same time, fear not: there is historical precedence. Urbi et Orbi.
