Quantum Computing Algorithms: Discover how a little math goes a long way

[paul nisset]

Hi ,
I've been curious about quantum computing for some time but have no practical knowledge of it.
I'm wondering how rigorous does ones physics knowledge have to be to benefit from your book ?
thank you,
Paul

I am really curious about chapter 4: „Qubit Conspiracy Theories“. What is this about?

[Barry Burd]

The Qubit Conspiracy Theories chapter is about quantum entanglement. I call it a "conspiracy" because it's as if two (or more) qubits conspire to yield the same value (0 or 1) when they're measured, even if they're several light years apart by the time they're measured. The strange thing about it is, nature doesn't know whether both will measure 0 or both with measure 1 until one of them is actually measured. This possibility bothered Einstein to the point where he thought quantum mechanics was incomplete. An experiment by John Bell has shown Einstein to be wrong about this.
Fun facts about that chapter: (1) I'm really proud of having included an explanation of Bell's experiment in the chapters; (2) My tendency to give chapters goofy names like this comes from my having written many books in Wiley's "For Dummies" series.

Thanks for the detailed explanation. I like the name you chose for that chapter and I am glad to hear that it‘s a serious topic and not about „actual“ conspiracy theories.

If you want real conspiracies, check the two chapters about security - Chapters 5 and 9. :-)

Sounds good!
