\_ Fixed the link.
\_ So it can solve a particular problem in one step instead of four.
Isn't that the result of a change in algorithm instead of a change
in the underlying electronics? How does switching to using atoms to
implement the logic make it possible?
\_ No, it is a change in the underlying electronics. Quantum
algorithms can't be done on non-quantum computers. - mikeym
\_ The fact that they successfully demoed this essentially confirms
that it is indeed physically plausible to implement the Quantum
Fourier Transform, which is at the heart of, among other things,
Shor's poly-time quantum integer factoring algorithm. Presumably
what poly-time factoring will do to computing needn't be
explained. Here's some reading for details:

\_ dude, I work in the industry, I don't understand this
crap. Should I go back to school?
\_ if you wanna work for peanuts as an academia phreak, YES
\_ if you want to understand it and/or contribute to it,
YES. if you don't, don't bother. it's rather unlikely
that there'll be practical industry demand for quantum
coders before you retire (or at least are too old to
pick up an entirely new paradigm).
\_ just wait for phillip's QC API --oj
\_ Too old? Like, his brain would seize up and he'd be
incapable of learning something new? All his bits
are in use? Unlikely.
\_ When you're 60, you will, in all likelihood, not be
to willing to learn a whole new world from scratch

This is a Sci Am article on the topic. For people who
haven't had Quantum Electro Dynamics in college (which is
like 99.999% of the world. :-)
\_ See second link above (LANL); it's perfectly accessible
for anyone smart enough to log in to soda and read the motd
(ie not that smart).
