Quantum multiple realities

Reading this article on a more advanced quantum computer I was reminded that I learned of a serious flaw in the “multiple worlds” interpretation of quantum mechanics.

I was attending a local physics lecture about basic quantum mechanics with Boy Two and the lecturer mentioned the multi-worlds interpretation. I asked whether he considered quantum computation a manifestation of this effect. He pointed out that wave equations are continuous but multiple worlds are discrete. Therefore you can’t ever get the exact right number of multiple worlds to make the probabilities work out. I found that quite a devastating point. Even if you just back up and say reality splits for every possible outcome it still doesn’t work. Perhaps it is possible to use the break down of distance at Planck length scales but that seems even more hand waving. I have basically given up on that interpretation now.

Show off.

Heh. It’s rare for me these days to actually find out something that changes my view, so I thought I would share a recent moment of that.
