Quantum Computing: What It Is & What It Can Do

[Spammers]

What is a quantum computer in short ? what does it look like ?
Can it be as fast as a present super computer ?

Another, beside crypto, what can quantum algorithms do ? Can they do something good like genetic algorithms ?

Read this info from caltech:

you should get a good understanding of what it's all about

Thanks, exequor. That was a good read.

Can it be as fast as a present super computer ?

Your question should be just the opposite. And the answer is NO.

what does it look like ?

Nothing like what most people have in mind, as far as a computer. Oh and only the most elementary experimental ones that contain around 4 qubits, maybe more, have been produced. As far as I know.

It depends on polynomial time.
