March Meeting Madness

The 2011 APS March meeting deadline for submission of abstracts is today.  Chris Fuchs writes with some stats about current submissions from the topical group on quantum information and in particular the number of quantum foundations talks (a list of foundation-ish talks is listed in the email):

As I write to you, 3200 abstracts have already been submitted for the APS March Meeting, with 140 of those earmarked for the Topical Group on Quantum Information.  Very importantly for quantum foundations, however, 34 of those abstracts (culled from all sessions) can be considered with good justification quantum foundations submissions!!  In other words, at the moment, we’ve got 1% of the whole meeting thinking about the foundations of physics!-

Have a look at some of the titles and speakers below; there are going to be some very good talks at this meeting.  It will be a grand opportunity for everyone in our community to mix and mingle and learn from each other.

Please don’t forget that the abstract submission deadline is tomorrow, November 19, at 5:00 PM EST.

I really encourage everyone who wants to see quantum foundations thrive and be memorable to please submit a talk to this meeting.  Encourage your colleagues and students too.  Let’s build a critical mass.  Your voice will count.

The place to go is:

http://www.aps.org/meetings/abstract/instructions.cfm

You must have an APS membership before submitting ($128 regular, $64 for recently completed PhDs, and $0 for students first joining), but you can still submit an abstract even if you don’t have your membership number yet–the instructions at the link explain how to do it.  (It is not necessary, but please do spend the extra $8 to join the Topical Group on Quantum Information, the official home within the APS for quantum foundations research.)

Sincerely,

Chris Fuchs

Rush Science

It looks like QIP talk accepts and rejects are out.  Sadly a piece of work I’ve been hacking on for a while didn’t make the cut (eventually it will make it’s way to the arXiv.)  But I did get one of the more amusing reviews sentences I’ve seen:

However, working this idea out seems to a require a protocol which is rather involved and, in some places, subtle.  Consequently, I was not able to work through and understand the construction in the time available.

Which is, perhaps, one of the best condemnations of the computer science conference system I’ve ever seen!

All rush and no play makes science something something.

Announcing the Quantum Information Science Announcement List

Back in the early days of quantum computing, one could almost keep up with the entire field by attending a few select conferences, reading the arXiv, and keeping in contact with a few colleagues.  Quantum information science (quantum computing, quantum information, and all its related brethren) is now a diverse and large field and keeping on top of everything is very difficult.  At the suggestion of Dmitry Maslov (who is currently a NSF Program Director) it seems that it would be very nice to have a general clearing house for announcements to send out to the community.  Thus this new blog.

So how will this work?  Well basically it will work just like any other moderated mailing lists.  You send in your announcement to .  It gets forward to moderator (currently only me, Dave Bacon, but am considering adding more once I get the tools to allow multiple moderators in place).  Then the moderators approve or reject your announcement.  It then gets posted to this blog, and put in the queue for an announcement via email to the mailing list.  This email announcement list will go out once a week, assuming there are announcements to be sent out.  You can subscribe and unsubscribe to the email list via this webpage.

In addition to subscribing via email, you can also follow the postings via rss (here is the feed) and on twitter (@qisannounce).  If anyone would like to include the RSS feed on their own blog they should feel free to do so.

Comments and feedback are, of course, greatly appreciated.

Doing My Part

Ryan Williams ACC. Which reminds me the other day a student of mine accidentally called coNP, coCP. Yep, turns out CP is a class. So the question is: will P versus NP be resolved before or after all two alphabetic symbol complexity labels are used up?

More APS March Meeting GQI Goodness

As a follow up to my last post, I’d also note that Chris Fuchs has set up what looks likes a great lineup for the March meeting.  Because not all of you are GQI members (join!) here is the email Chris sent out that describes the lineup:

Dear GQI Membership,

I write to you as the chair-elect of the GQI executive committee and the program chair of our portion of the 2011 APS March Meeting.  This coming year the meeting will be in Dallas, Texas, 21-25 March 2011.

We believe we have put together an exciting venue of invited talks and focus sessions.  Please have a look at the attachment (see below) and you will see.  There will be some astounding experiments reported, and you will also have a chance to meet several of the founders of our field.  2011 is a hallmark year for quantum information as a field within physics  Also we are pleased to announce that one of our talks will be given by one of the two LeRoy Apker Award winners for “outstanding achievements in physics by undergraduate students.”

I should further mention that the meeting will host a talk from one of this year’s Nobel-Prize winners for the discovery of graphene, Konstantin Novoselov.  (Andre Geim may also speak, but has not yet confirmed.)  Moreover, there will be a recognition of the 100th anniversary of the discovery of superconductivity with a session of historical talks devoted to the subject, as well as a  Nobel-laureate session on it.  Speakers will include Ivar Giaever, Wolfgang Ketterle, Sir Anthony Leggett, K. Alexander Mueller, and Frank Wilczek, and there is word that there may be more.

In all, it should be a more-than-usual memorable meeting, with some quite wonderful GQI invited and focus sessions.  The executive committee and I hope the venue will be exciting enough to tip the scales for you if you have been indecisive about attending.

Particularly, we encourage you to submit a talk or poster on your latest  research.  The better showing GQI makes at this meeting, the greater the chance we have of increasing general APS awareness of our field, the better the chance the topical group may recruit enough members to attain APS Division status, and, MOST IMPORTANTLY, the better the chance we have of convincing American physics departments that it is worthwhile to create faculty and research positions for all of us.  Your participation is really, truly vital.  Quantum information needs you!

This story shall the good man teach his son;
And Crispin Crispian shall ne’er go by,
From this day to the ending of the world,
But we in it shall be remembered—
We few, we happy few, we band of brothers;
For he to-day that sheds his blood with me
Shall be my brother; be he ne’er so vile,
This day shall gentle his condition;
And gentlemen in England now-a-bed
Shall think themselves accurs’d they were not here,
And hold their manhoods cheap whiles any speaks
That fought with us upon Saint Crispin’s day.

Please note that the deadline for abstract submission is NOVEMBER 19 (less than 11 days away!).  Please submit an abstract yourself; please get your students to submit an abstract too!  Please get your associates to submit an abstract as well!! The place to go to submit and register for the meeting is here:

Quantum Foundations at the APS March Meeting

If you’re a member of the APS topical group on Quantum Information (GQI) you recently received an email from Chris Fuchs about the upcoming APS March meeting (to be held in Dallas, Texas this year.)  If you’re not a member, shame on you, you should become a member!  But more importantly Chris has made a very good effort this year to have a good showing of talks from the quantum foundations community.  There is a focus session this year, “Quantum Information for Quantum Foundations” with Giulio Chiribella (Perimeter Institute for Theoretical Physics) as the invited speaker.  Giulio will give a talk titled “Toward a Conceptual Foundation of Quantum Information Processing.”  Further Anton Zeilinger (University of Vienna) will be giving a symposium talk, “Quantum Information and the Foundations of Quantum Mechanics: A Story of Mutual Benefit.”

One of the explicit reasons for forming GQI, in addition to the explosive growth of quantum information science, was a place for all who are tightly tied to quantum theory and in particular for quantum foundations folks.  The mission statement of GQI makes this explicit:

The Group is committed to serving as the home within the American Physical Society for researchers in the foundations of quantum mechanics. The Topical Group will promote a continuation of the active and beneficial exchange of ideas between quantum foundations and quantum information science.

Over the years this has resulted in varying degrees of success.  I can remember a few foundations sessions at the March meeting that were top notch and very interesting, but increasingly there has not been a strong foundations showing.

I would, of course, encourage all quantum information related people to attend (submit a talk or a poster) to the March meeting (at worst you’re going to learn about the very exciting superconducting qubit experiments occurring at places like UCSB, Yale, and IBM) but I would particularly encourage you to submit a talk or a post if you are from the quantum foundations community.

My personal view is that foundations work lies very deep in the heart of quantum information science.  Not necessarily for the grand old debate about the interpretation of quantum theory, but because foundations seeks to bring conceptual clarity to a subject whose mystery is what we are trying to exploit.  So foundations people come out of yer closet and help shed some crazy light on quantum information science!

 

Quantum Article Parse Failure of the Pontiffical Kind

Two observations from yesterdays New York Times article about quantum computing (Moving Toward Quantum Computers.)
First, the drawing accompanying the article (here) is interesting to me.  I wonder where they got the idea for it and whether this idea involved Q*bert, color codes, or topological codes?  Or was it just the same old: we have no idea how to draw a quantum computer, so lets just make a cool looking graphic?
Second, I find this sentence fascinating: “D-Wave has built a system with more than 50 quantum bits, but it has been greeted skeptically by many researchers who believe that it has not proved true entanglement.”  Emphasis mine.  Okay I find it fascinating not because of the debate about the quantum nature of D-wave’s machine, but for its language.  If there is “true” entanglement, what is “false” entanglement?    Further for some reason I can’t quite pen down the sentence strikes me as awkward.  In particular it feels like it needs to be something more like “that is has not proved that its system possess real entanglement.” (Yes I understand the sentence, yes I’m not good at reading comprehension, and yes I’m beyond pedantic.)  Am I the only one having a hard time parsing this sentence

Shor on Shore

The important thing is to never, ever, ever pass up an opportunity for a bad pun. Especially a bad pun that might by some strange coincidence be stumbled upon by Wim van Dam or Michael Freedman while out taking a walk pondering the secrets to the quantum computing universe 🙂 Though I will say that this circuit is not resistant to the correlated errors that are waves that will soon wash it away.

Optimizer PECASEd, NyTimes Quantum Computing

Congrats to Scott Aaronson, aka the Optimizer for winning a Presidential Early Career Award for Scientist and Engineers. Scott, please remember to ask Obama for more dollars to build a big old quantum computer 🙂 Cheaper than a spy satellite, we promise.
In other news, an article in the New York Times about quantum computing is here. Mentions IBM, Yale, UCSB, ion traps, photon sources, and S-wave P-wave D-wave.
