Today, I looked on the arxiv and found arXiv:0804.0272:
arXiv:0804.0272and nearly fell out of my chair. What an awesome title. A least for me, when I first parsed the title of the paper, the first thing that popped into my head was using spatial dimensions to speed up quantum computation (as opposed to using higher dimensional quantum systems.) Gots to get me some string theories to build my quantum computer :) (Oh and the paper is pretty cool as well!)

Glad you like it! (The title *and* the paper, that is). Now if only you were one of our referees...

If I good understand, quantum gates C-NOT and Tofoli was doen, but to perform quantum algorithm need too much such gates and this couse inperfection at very high level?

Is that you "possible?"
