Last week I was in Boulder for a workshop on ion trap quantum computing. Basically nearly everyone who is working on ion trap architectures for quantum computing was there, which was pretty incredible. A highlight of the workshop, besides the excellent experimental results, was that I got to see one of the participants describe how [...]
This last weekend I attended two out of three days of the SQuInT conference in Albuquerque, NM. The conference, as usual, was stellar, and was rather large this year, with nearly 150 people! The only real draw back this year was that the hotel the conference was in had variously scheduled (1) a band, and [...]
After class today (literally) I head off on quite a journey. Albuquerque to Boulder to Seattle to Santa Barbara to Seattle to Santa Barabara to Seattle. Those Seattle waypoints? Laundry and getting my wisdom teeth pulled. Unfortunately I’ll be missing the first day of the SQuInT conference, but maybe I will be able to blog [...]
A good way to get your blood pressure elevated is to read Richard Cohen’s opinion article in the Washington Post where he slams requirements for learning algebra in high school. What I love about the article, though, is that he admits, right of the top, the following I confess to be one of those people [...]
(Note: the above title must, I repeat, must, be said in the voice of the comic book guy from the Simpsons.) Over at Uncertain Principles there is a vote going on about the greatest physics experiment ever. You can vote for the eleven choosen here. Among the eleven are Alain Aspects Bell inequality test! You [...]
Today’s talk, powerpoint posted once I touch up the presentation: 04:00 PM Condensed Matter & Atomic (CMA) Physics Seminar Dave Bacon, University of Washington, Computer Science & Engineering Building Robust Qubits Using Many-Body Strongly Interacting Quantum Systems C-421, PAT (Physics) The late Rolf Landauer liked to say that “information is physical.” By this he meant [...]
Alicki, Lidar, and Zanardi have put out version two of their paper critiqueing the assumptions of the threshold theorem for fault tolerant quantum computation. The new title of their paper is “Internal Consistency of Fault-Tolerant Quantum Error Correction in Light of Rigorous Derivations of the Quantum Markovian Limit” and is found at quant-ph/0506201. Discussions about [...]
The latest additions will probably have lots of errors (well even more than my normal notes!) as I haven’t taught from these notes yet and I always find errors when I teach. (Plus they are on error correction!) But this completes this set of notes for this quarter. I’ll probably give these notes a good [...]
Most people in quantum information science try to be sensitive to not overhyping the field. (Okay, so I get a little breathless sometimes!) This, however, is pretty amusing. I especially like But could you imagine not using a Quantum Computer to come up with the most efficient sequence of nanobots to administer the cure to [...]
Hindsight I taught things a bit out of order. What I should have done was do entanglement after Grover’s algorithm. Then it would have been nice to have a lecture on quantum communication complexity, but seeing as how things are rapidly heading towards the end (four more lectures to go) and I want to get [...]
