Since when is quantum computing based on a multiverse?
https://en.wikipedia.org/wiki/Quantum_computing
…a quantum computation could transform the memory into a quantum superposition of possible classical states…
Quantum superposition is the key word. https://en.wikipedia.org/wiki/Quantum_superposition
Quantum superposition doesn’t imply multiverse. The so called Many-worlds interpretation is science fiction: https://en.wikipedia.org/wiki/Many-worlds_interpretation
Besides, multiverse word is used in more than one context. One scientific interesting context that is: https://medium.com/starts-with-a-bang/the-multiverse-is-inevitable-and-were-living-in-it-311fd1825c6
I advice against using common logic on complex contexts such as Relativity, cosmological or quantum theories. Some implications of these theories are counter intuitive, still they are better explanations than the intuitive ones…
Example? There are 2 observers A and B, B moving quite fast from A. If A observer sees a clock of B ticking slower, does it mean that the other observer B will see a clock of A ticking faster? No, it doesn’t.
