In the grand scheme of things I am not a fan of picture books for grown-ups, which this kind of is. But, if you are going to do something like this, it is one of the better ones I've seen.

It's not something to go for if you've already absorbed the contents of a more substantial quantum title, such as the author's own The Quantum Age , but if the whole business currently leaves you mystified, this would be an excellent way to get started.
