no, it can’t actually be made simple. Qbits are fundamentally unfamiliar. They have restrictions like “you cannot copy them” and “all operations must be reversible”. And what you get at the end is basically flipping a weighted coin, where the probabilities are constrained by the operations you did earlier. The only way to understand it is to immerse yourself in it. Think: motivated grad student, not puppy.

I'm pretty sure they can't. What it's not, though, is running all the programs at the same time.
