> Do you multiple a qubit of infinite values against a quibit of infinite values and have all possible results?

The accurate answer would be "no", or at least "thinking that way will lead you to believe that they're more powerful than they are".

In particular, quantum computers won't allow you to solve NP-hard problems in less than exponential time, not unless there's something we're missing in the math.

That said? Since I don't have the chance to describe it better right now, you can start off by thinking "sorta, yes".
