I’m at SQuint 2007 which is being held on the campus of Caltech this year. Quite a turnout this year: something like 150 people attending! In fine Caltech tradition the night of my arrival I got pretty much no sleep. And I keep getting the feeling that I have a homework due somewhere on campus.
\nCool work by Patricia Lee at NIST:<\/p>\n
\nAbstract. We report on the experimental demonstration of radio frequency addressing of atoms in every other site of a double-well optical lattice, independent of their nearest neighbors at a distance of less than an optical wavelength. By dynamically controlling the lattice and the vector light shifts, the atoms’s spatial and spin degrees of freedom are entangled in each double well. We have also observed a coherent spin-exchange interaction between pairs of atoms in the double-well lattice, which can be used as a mechanism for a square-root-of-swap gate.\n<\/p><\/blockquote>\n
During the talks on quantum error correction, it was mentioned that in the very cool threshold paper of Aliferis, Gottesman, and Preskill (quant-ph\/0504218<\/a>), they call the inductive proof of the threshold theorem for fault-tolerance the “threshold dance.” This, of course, brings up the interesting question of what the dance moves are in this dance and the even more important question which is should this dance be part of my upcoming wedding? <\/p>\n","protected":false},"excerpt":{"rendered":"
