On what plane of existence do quantum computations occur?

[TunnelingthuWorlds]

TL;DR

Dimentionality, Many-World-Hypothesis

I was recommended by another mentor to purchase a good book on MWI, which I think should be a thread or poll of its own.

Anyway, I might have debased myself too much in that other topic, as I understand on an abstract level how QM works.

In my own words, I feel as though possible worlds are separated in some sense, otherwise, counterfactual definitiveness would never occur, and statistics would blow up.

Yet, much how we build tunnels through mountains instead of traversing over them, I believe that something similar in principle (and if not in principle, then why not) could happen between possible worlds.

To stop the meandering, I will simply ask, on what plane of existence do quantum computations occur?

The term "plane of existence" is meaningless. So this question is not answerable.

This is personal speculation and is off limits here at PF.

Your questions do not support this claim. Please take the time to work through a textbook on QM and learn how it actually works.

This thread is closed. Please do not post another question along these lines; you have already posted several threads that, as you appear to recognize, have not gone well. The way to change that is not to keep posting questions as they occur to you. It is for you to take the time to learn QM.
