Quantum math: where 2 x 0 does not equal 0

Of course! But what is dependable in quantum anything? I guess only that it always has surprises.

I mean, who would have thought that an atom here and an atom on the far side of the universe had anything to do with each other? And by changing this atom you change things over there at the exact same instant? Meaning, of course, that there is something faster than the speed of light. Oh, and this whole “changing” thing has been proved.

But this is exactly what has given rise to the situation where 2 times zero does not equal zero. A flaw in basic mathematics, but not, seemingly, in quantum mathematics.

Confused? I know. Me too. So go to this article in IEEE Spectrum and get the whole story.
