Perhaps sensibly, he doesn't even try to explain it in detail. In other words, we haven't a clue. So if we can't understand it, we have to take it on trust, which I think suits Kaku too, as he spends most of the book telling us what extraordinary achievements these machines 'may' do. Kaku's book is really an extended exercise in hi-tech wish fulfilment, with each chapter detailing a currently intractable problem that the quantums 'may' be able to solve
Author throwing shade left and right, clearly thinks Kuku is full of shit. And he's right.
Quantum computers will never replace silicon-based digital computers. They're actually much, much slower than current computers, and completely unsuited for general computation. They can only solve a few very specific math problems very quickly, in theory, maybe, by using some physical properties of quantum interactions to side step the expensive computations and arrive at the result using a shortcut.
Kind of like tide-predicting machines used a series of pulleys to effectively compute and graph very complex tide predictions, long before computers were a thing, and for a while after, by simply turning a wheel. But they were unsuitable for anything else. You could never make a general purpose computer out of that. And eventually they became obsolete, when digital computers became fast enough to beat them without needing an analog shortcut.
they're talking about SPECIFIC problems being solved by quantum algorithms; it doesn't do away with classical computers. ever. you could theoretically run a quantum computer as a classical computer but the expense is too high, and will be for a long time, like the beginning of classical computing. the moore's law of quantum computers hasn't been observed yet (that I know of).
I get the impression that there are diversity hires working on these quantum projects, as they should have a certain path forward by now, for at least a little while, and it makes no sense for the research to be stalled out

The QC hype will never pan out. It's vaporware.

You dont understand what quantum computing is

Quantum computing will never be a thing for us peons.
