Want to understand quantum computing and related techonology?

It was more a clever play on the fact the original post is about a book that 'quite interesting and relatively approachable' and NotAClueOutsideUK asked a question the book can answer.

Maybe it wasn't that clever

No not really. "It's in this 900 page book" is not really that helpful an answer to a very basic question.

Anyway I'm convinced quantum computing is either the next big thing, a total gimmick, or possibly both/neither.

Understanding Quantum Technologies, by Olivier Ezratty

Seriously, the author says he is an IT specialist and on a brief skim so far, it looks quite interesting and relatively approachable.

On his blog at http://www.oezratty.net/wordpress/ (mostly in French, sadly) he says of this free ebook:

I have a Quantum computer at home. It is neither switch on or off until I see it.

Can it reheat my tea?

It will only choose one when you observe it.

It's a bit like PC in that regard. It will only act like a moron if someone is watching it.

Does it choose, or do I?

Does it choose, or do I?

That is chosen by another observer who is observing you observing a quantum state, and so on. It's a virtuous circle, like this:
