heh, yeah, that sounds a lot like back in grammar school. gotta love quantum physics!

*note to my teacher if you should ever read this: make sure you explain em-waves better next time! nobody in class got that, at all!*

From what I read of the abstract it seems like marketing speak because the inherent nature of the computer is the fundamanetal properties oif quantum mechanics which unlike a current cannot be turned off. The trick however is that extracting the information from the qubit does require work so while the computer might be doing the calculation while it is off, it always has to be on to get it to tell you.

While I have a great deal of respect for the Kwiat group (He and Bouwmeester are easily tops in this field) the whole field is so overhyped and overmarketed that every little things gets hyped. This seems like a good paper but not IMHO Nature worthy as we're not going to see muich come of this in the next five years.

Wait... you mean the article is serious?? I thought it was a joke all along o_O I even laughed when it suggested not running the computation at all to make everything less error-prone...

This means we can compile gentoo stuff in a "parallel universe" while we're doing other stuff in our own universe. (Read the article and you'll see that this is theoretically not impossible at some time in the future)

Actualy, the article is more or less correct. The interpretation is just off a bit.

Quantum computers, by nature, work by not working. That's why they are so fast. The idea is that all the possibilities are always present, it's the act of taking a mesurement that "fixes" the awnser in time. The basic principle is that the actual calculation gets done in a different dimension, making the work appear instantanious (spelling?). Note that we're talking dimension in quantum physics, not sci-fi movie phisic. Basicaly, it's a different axis on the graph. You normaly have xyz for length, width and dept. This one takes place in something that would come after Z. (at least, that's my understanding of it)
