Interesting. Sounds like you’re saying that the entire process of quantum computation aims to keep the system coherent, and so avoid splitting the universe. Which make sense. They tell me the difficulty, in an engineering sense, is to stop the system de-cohering.
Yes. Except that the universe doesn’t ever split. It’s always continuous. But we’re trying to keep two blobs of amplitude in close contact rather than letting them diverge, so that some parts can overlap and add up or cancel out.

Is that remotely accurate?
