Multiverse Explanations

Note: This article assumes the existence of the multiverse - the many-worlds interpretation (MWI) of quantum mechanics. Nothing beats MWI for its sheer ability to explain quantum phenomenon. If you believe that science is primarily about explaining things and not just predicting them, then MWI is for you. Quantum computers will be in the spotlight soon with the upcoming announcement of their supremacy . It’s common knowledge that a quantum computer is implemented with qubits, and qubits take on multiple values at the same time. But how exactly do they do that? And how exactly does the computation take place? Enter the multiverse. First some background: modeling quantum phenomenon is a computational task that rapidly becomes intractable using normal, classical computers. In the early 80s, Richard Feynman realized that quantum behavior *itself* was a form of computation. For example, the pattern made by interfering photons on the wall of the double-slit experiment is a form of comp
