Quantum Computers
-
I must admit: I am totally ignorant about quantum computers. The only essential thing I have managed to pick up is that it has very little to do with traditional digital computers. Maybe as different from digital computers as the analog computers 40-50 years ago, those that you programmed by setting up a circuit on a plugboard, using Lego-like bricks that were integrators, derivators, adders, amplifiers/multipliers, ... I guess that I will never get in touch with a real quantum computer. Yet I'd like to know what they are, at a far deeper level than provided by a single article. More like a college level textbook. One that doesn't require you to know in advance what it is, before you start reading. (I am not specifically referring to the Wikipedia article :-).) I am curious about how you analyze a problem suitable for a quantum machine, and how you transfer that problem to a 'program' (if that is the term used with quantum computers). I'd like to learn which problems are suitable for quantum machines and which are not (and why they are not). Does anyone know of a textbook on the subject, suitable for a reader with fairly thorough insight into traditional digital computers, but totally without a clue about quantum computers? Is quantum computing taught at tech universities as an engineering discipline? What textbooks do they use? Or should I wait for another five or ten years before asking such questions?

There's this: [Learn Quantum Computation using Qiskit](https://qiskit.org/textbook/preface.html) No quantum knowledge needed, but there's plenty of linear algebra and other math, and it's the real deal, not yet another inaccurate popscience description of quantum computing.

I skimmed through the first couple chapters of this, and it looks great! It starts at a rather elementary level: You could give this text to a high school kid, who would most likely follow it well. That is fine! The presentation is very pedagogical. Maybe, after having worked through all of this, I will ask for something that goes even deeper; then I will know a lot better what to ask for. Or maybe this is how far I can manage to follow it :-) Thanks a lot for the link. I will be forwarding it to others who want to learn the fundamentals of quantum computers.

I understood everything about quantum computers and my answer is yes and no.

They can "test all solutions at the same time"; making me think of analog / functional computers. Since everything vibrates at some level, I think it's trying to tap into that.
"Before entering on an understanding, I have meditated for a long time, and have foreseen what might happen. It is not genius which reveals to me suddenly, secretly, what I have to say or to do in a circumstance unexpected by other people; it is reflection, it is meditation." - Napoleon I
