O brave new quantum world!
You know you’re on a list of physicists when you start getting emails like
from: he he
subject: why you are you? Physics doesn’t determine everythings.
Reminds me of my good old graduate student days (oh, and by the way: “Go Bears!”) when the “uncertainty principle was untenable.”
Yesterday I went to the Friends of the Seattle Public Library’s book sale. It’s always fun to see a line stretching out into the distance for people waiting to get a chance to buy used books at less than one dollar a book. Here was my take this year, where I happily picked up a copy of Messiah and Griffiths, both of which I sadly never had in my library:

Via Science after Sunclipse, I find a comment by Greg Egan on The n-category Cafe where I was led to this letter to New Scientist:
Superluminal siblings
22 September 2007
From New Scientist Print Edition.
Nick Webb, London, UK
Robbie and Fred are twins who live together. Wearing identical suits, they leave their house at the same time heading in opposite directions. One twin carries a hidden green wallet; the other has a red one. The wallets are not visible.
Unfortunately, Robbie is mugged and the redness of his wallet is revealed. In quantum terms he is measured and forced to take a value.
An observer can now deduce that Fred’s wallet is green, and if put to the test this will prove to be the case no matter where or when Fred is interrogated.
There is no need for faster-than-light communication or spooky interaction at distance – just knowledge of the initial conditions. I can’t see anything wrong with this analogy. Am I missing something?
The editor writes:
No, it’s exactly right.
At which point my brain just exploded.
Don’t ask Microsoft Excel 2007 that question!
Michael Nielsen’s switchin’ fields. I’m envious but also sad. Envious that he gets to do something totally cool and new, but sad that I won’t be randomly bumping into him at conferences where I try to explain to him some crazy idea I’m working on and then get to hear his wonderful laugh at my silly ideas. Oh yeah, and when am I ever going to get to use this joke again, huh?
On the more serious side of things, I myself often think about what I would do if I wasn’t working in quantum computing. Which always leads me to think about why I’m still in the field in the first place (history ain’t a good reason, in fact I’d say it is the worst reason of all.) There are mostly two or three things that really keep me in the field these days. One is that I really really really want to see a quantum computer built. And I think the current roadmap ain’t got nothing to do with how a large scale quantum computer will be built. I’ve always said that if I could see how some scheme for quantum computing would really work to build a large quantum computer I’d drop my theorists clothes and work towards building the damn thing. And I work today in the field because I’m naive enough to think that I might be able to contribute to the more radical ideas I think are needed for building a quantum computer.
The second thing which keeps me going these days is a personal quirk. When I first started working in quantum computing I was trying to solve NP-complete problems efficiently on a quantum computer. I was young and I was naive, yes. But I was also drawn to the promise of the power of quantum algorithms. And damnit I still want to come up with an algorithm for a quantum computer which is of some importance. Yep, I really really really want to at least break a public key cryptosystem!
Finally I would say that the other thing which keeps me in quantum computing these days is just to see what Scott Aaronson will do next. Actually what I really mean by this is I do think that quantum information science provides an interesting insight into computation and into physics. Quantum computing beyond the hype of a quantum computer. Quantum computing for its own intellectual sake of revealing more about our physical and computational universe. Quantum computing because (to channell Feynman’s ghost) our world is quantum damnit, and all these views of the interaction betwen physics and computer science which just go with classical computing are interesting but fundamentally lacking.
Of course all this thinking about what keeps me in the field of quantum computing or even in academia also is just my way of avoiding answering the question of what I would do if I wasn’t in the field. But that’s easy for me to answer I guess. I’d be at a computer startup (my original goal in life was to work at Apple, you know) or trying to get a job at someplace like D.E. Shaw where my friends who work there tell me exciting stories of interesting problems and silly sums of money which will let them do what they want in a few short years. Or maybe I’d be a lift operator at a ski resort 🙂
Here is an awesome position for one of you bigwigs out there:
The Board of Electors to the Professorship of Quantum Physics, to be held in the Department of Applied Mathematics and Theoretical Physics (DAMTP), invite applications for this Professorship, to take up appointment on 1 January 2008 or as soon as possible thereafter. Applications are welcome from persons working in the broad areas of quantum computation and quantum information theory (with these taken to include quantum cryptography and quantum communication theory). The Professor will have an outstanding international reputation in their field of research and will be expected to provide strong academic leadership in research, teaching and other activities of DAMTP.
The Chair has become vacant on the departure of the post holder, Professor Artur

Oh, and to translate this post across the pond, “centre”=”center” and “1 January 2008” is “January 1, 2008.”
MacArthur awards for 2007 have been announced. Seattle scores two, Yoky Matsuoka (right here in my own department!) and Mark Roth at the Fred Hutchinson Cancer Research Center. My old alma mater (“nourishing mother?”) Caltech received two awards, and my grad school alma mater Berkeley received one.
I think I am begining to understand why I have an inferiority complex.
I know they exist because slashdot and The New Scientist and some other Site tell me they exist. I keep wondering how I can find my way to a parallel universe where I don’t spend my time reading those articles, but can’t quite get the Hadamard matrix to enact the proper interference pattern.
The deadline for QEC07 contributed talks and posters is only a week away, September 30. Contribute, peoples! (The deadline for registration is Halloween October 31.)
The deadline for TQC 08 is also September 30th.
So who wants to try for the difecta and spend all night on the 29th preparing to submit?!
Sports Illustrated says that Caltech is number one! Err, had the number one college sports prank:
1. The Great Rose Bowl Hoax
School: Rose Bowl
Year: 1961
Today, Caltech has no official mascot, much less a football team. But until 1993, the Rose Bowl was home to the mere technical school’s football squad — as well as the culminating event of college football. In 1961, a team of 14 students decided to capitalize on the event’s irony by changing the University of Washington’s flip-card stunt at half time.
A student disguised himself as an eager reporter from a high school newspaper and interviewed a cheerleader to get the details. They found that by surreptitiously altering 2,232 instruction sheets, the entire Husky fan section could be duped into displaying any pattern the “Fiendish Fourteen” desired — without the crowd realizing it. They stole the instructions, printed modified copies, and replaced them.
On game day, the college card collage played out as expected for the first 11 patterns, lulling the crowd into a sense of security and drawing the lenses of (color) national television. Subtle alterations to the 12th pattern resulted in a Husky that looked an awful lot like a beaver — the dam-building totem of many technical schools. The 13th stunt came off as a mistake: “HUSKIES” spelled backwards. And finally, the 14th stunt spelled “CALTECH,” and it all made sense, casting silence upon the stadium for a few moments. Soon, laughter set in among the crowd and panic among the Washington cheerleaders, who cancelled the final stunt, which was wisely left unadjusted by the pranksters.
But, ahem “Mere technical school?” Note that MIT didn’t even make the list. 😉
