Soon enough we’ll have bands playing on unplugged keyboards and sound will still come out of the sound system.. hmmm .wait .. doesn’t that already happen ?! DICE!

…and now I laugh at the jerk who told me my interest in quantum physics was “Silly because it (quantum physics) isn’t real, it’s just a bunch of made up stuff that no one can do anything with.”

I read the original article in Nature. The R(pi/2) function is applied before the Grover algorithm, which puzzles me, since you need an external computer to do that calculation.

Moreover, they use five detectors. For a given qubit, they should only need four if they didn’t use the goddamn R(pi/2) function before the Grover algorithm.

So while the whole “we can do counterfactual quantum calculations without turning on the computer” is nice, but still requires a computer to be on.

Shoot… I left the PDF at work. I think it was a sorting algo. They were using a qubit two bit system and Grover’s took out the “wrong” two, and then it got another R(pi/2) which would presumably eliminate one of the two of the remaining two.

I blame my headache on you!!!

Head hurts, trying to understand!!!

Heh….

That is so far beyond my meagre comprehension I won’t even feel the brain pain the idea incites for several thousand evolutionary steps.

acomputer to be on.What was Grover’s used for, though? Was it just for a single entity, or a hypothetical NP-complete solution, or…?
