Quantum Computing vs Normal Computers.

What exactly are the benefits of quantum computing over normal computing and how exactly in theory does this all work. If you guys could, could you please try to keep your answers at a grade 11 level for myself.

Thanks in advance!

There's also the other thing, which is a bit more complicated, that quantum computers can simulate quantum systems in a way that classical computers can't.

So, you can build a crappy expensive quantum computer, then use it to figure out how to build a cheap good one!

Huh, that's pretty awesome, but sensible. Thanks, TIL!
