O brave new quantum world!
Okay, I think it is time I give in and create a category on the blog called “Bacon.” Two new entries for the category:
Self promotion for those around the University of Washington campus: I’m giving a talk in the physics department at UW. Mondays, October 20 at 4:00 P.M. Ronald Geballe Auditorium, Rm. A102 (cookies at 3:45):
Title: “Who Will Build a Quantum Computer: the Physicists or the Computer
Engineers?”
Abstract: Building a quantum computer large enough to perform a task beyond the capability of today’s classical computers (breaking a cryptographic code or simulating a complex quantum system) is a daunting task. On the fundamental side, this difficulty arises from the fact that quantum systems like to decohere, and that we cannot control a quantum system with perfect accuracy. On the technical side, the obstacles toward build a quantum computer arise from the severe engineering constraints imposed by manipulating individual quantum systems. The theoretical solution to the problems of decoherence and lack of control was worked out in the nineties and is known as the threshold theorem for fault-tolerant quantum computing. The great debate in quantum computing today is how the technical difficulties of building a quantum computer will be overcome. In this talk I will outline two very distinct camps on how this will be achieved: one centered very squarely on engineering and the other with roots in condensed matter physics. This is a battle for the soul of future quantum computers and will determine whether quantum computers are years, decades, or centuries away from being built.
Garrett Lisi, surfer and creator of possible theories of everything, has given a TED talk:
I had never thought to put Schrodinger into the box.
“I try to balance my life between physics, love, and surfing. That way even if the physics I work on comes to nothing, I’ve lived a good life.” Word.
I wonder how many people this week realized that “ten percent down” followed by “ten percent up” does not equal “no change.” Probably a few. And how many realized that “ten percent down” followed by “ten percent up” is the same as “ten percent up” followed by “ten percent down”? Or that up 5 percent, down 3 percent, up 2 percent, down 8 percent, and down 8 percent in that order is the same as down 8 percent, up 2 percent, down 3 percent, up 5 percent, down 8 percent in that order? Commutativity is cool. Yes, I am easily amused.
A new entry in the best title every competition:
arXiv:0810.0827: Sine function with a cosine attitude
Authors: A. D. Alhaidari
Someday I promise that I will use the phrase “an exponential function with a logarithmic attitude.”
From the annals of strangely mixed news stories. Canada: $25 billion government bailout and….$50 million for the University of Waterloo’s Institute for Quantum Computing:
BRANTFORD, Ont. — The $25-billion government deal to buy mortgages from Canada’s banks isn’t a lifeline for lenders stuck with bum loans, Prime Minister Stephen Harper said Friday…
He said the government will likely make money on the deal, because its borrowing costs are lower than those available to banks.
Harper also produced an election goodie, promising a $50-million grant to a high-tech research lab at the University of Waterloo.
The money goes to the university’s Institute of [sic] Quantum Computing.
The prime minister says it’s in line with the government’s efforts to spur research and development.
A new way to get out of the financial crisis: invest in the quantum computing! (joke about a superposition of rich and poor deleted for sanity’s sake.)
You know it’s a heavy volume day when even Google can’t handle it:
Your message could not be posted to the DOW JONES INDUSTRIAL AVERAGE INDEX group because there have been too many messages posted to the group recently.
Fear
Google’s view of capitulation
Irrationality?

Another hundred year reference: the Cub’s ticket market.
Let’s blame Van Buren:
Not just grades but:
Today, when information storage is cheap, why is it that we have a grading standard consisting of a few lousy letters (less for some schools..you know who I’m talking about!) Should we shoot for a standardized more information content grading standard? Or is the current system fine for the purpose it serves (which varies widely among the users of the grades)?
A priceless new email feature for gmail: Mail Goggles:
Sometimes I send messages I shouldn’t send. Like the time I told that girl I had a crush on her over text message. Or the time I sent that late night email to my ex-girlfriend that we should get back together. Gmail can’t always prevent you from sending messages you might later regret, but today we’re launching a new Labs feature I wrote called Mail Goggles which may help.
When you enable Mail Goggles, it will check that you’re really sure you want to send that late night Friday email. And what better way to check than by making you solve a few simple math problems after you click send to verify you’re in the right state of mind?
Now if only Google would add a similar feature for those hitting the reply to all button (instead they apparently have a function to make it the default reply option. Doh!)
