This weekend the grapes for my second “real” batch of wine were delivered to Mountain Homebrew and Wine Supply. Last years vintage, Villa Sophia “La Gruccia” was a success in that it didn’t turn to vinegar and that over time it is definitely mellowing out, but I wouldn’t say it was a fantastic wine. This year I’m a bit more hopeful and have some ideas for how to modify my process to produce a better wine.

Visiting Stanford and Cal
I’ve spent the last two days in the San Francisco bay area visiting first Stanford and then Berkeley.

Hippy Pontiff
Turn your face into a name (via torque). The “quantum pontiff” apparently has long hair:
Shorter Bruce Schneier: "Trust My Blind Faith in Cryptography"
Bruce Schneier has a commentary up at Wired about quantum cryptography. There are a lot of good points about the article, but it left me kind of scratching my head. As far as I can tell Bruce Schneier believes that you should not worry about any cryptographic system currently in use ever being broken. I didn’t think cryptographers were allowed to have so little paranoia.

Quantum Algorithms Zoo
Stephen Jordan, now a postdoc at Caltech, has produced a useful little guide to quantum algorithms: a zoo of quantum algorithms. Help squash the myth that all there is to quantum algorithms are the algorithms of Shor and Grover!
Majority Gate Reality
The universe doesn’t always operate the way we want it to. No, I’m not talking about the stock market (unless you’ve been short lately), I’m talking about the role of error in logical deterministic systems! When you zoom down far enough into any computing device you’ll see that its constituent components don’t behave in a completely digital manner and all sorts of crazy random crap (technical term) is going on. Yet, on a larger scale, digital logical can and does emerge.
Today heading to work in the early dawn I was pondering what all of this meant for our notion of reality.

Krugman on Krugman
A very good essay Paul Krugman wrote on his method of doing research. Some good gems in there for researchers of all fields.
The injunction to dare to be silly is not a license to be undisciplined. In fact, doing really innovative theory requires much more intellectual discipline than working in a well-established literature. What is really hard is to stay on course: since the terrain is unfamilar, it is all too easy to find yourself going around in circles.
Ski Season Begins
It’s official: Loveland and Arapahoe Basin are open for the 2008-2009 ski season. Eighteen inches of man made snow may or may not, however, be considered good news.
Bacon Robots
Okay, I think it is time I give in and create a category on the blog called “Bacon.” Two new entries for the category:
- Bacon Robots. Think, people, before you start sizzling up the Bacon that falls from the sky.
- Bacon and Donuts: Taste We Can Believe In.
War I Tell You
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.
