Totally amazed at the level of this quantamagazine article. Superb stuff. They even manage to explain string-nets. I keep thinking that you could make an interesting iPhone game out of this.
Actually it's nice to read a bit of a summary of the field, including the history.
Here is another good article discussing the open problem of the existence of a quantum memory [1]. The story goes like this: your hard-drive stores bits of information in little magnets. That is magnetic order, which falls into the symmetry-breaking paradigm discussed in the article. When you turn the computer off, it remembers what's on your harddrive. Those magnets keep the bits protected, by virtue of the "magnetic order". Now here's the question: can we do the same thing with quantum bits? Even theoretically, is it possible? Is there some kind of "quantum ordered system" that will protect a qubit?
