Fact, fiction or best left in a superposition of states of indeterminate outcome? Do you think it might be powered by Cold Fusion?

Quantum computing is, so far, very limited. The number of Qbits to do anything really useful is measured in the tens of thousands, and I recently read an article which said a research team had, with the aid of a seriously big NMR unit, acheived 7 Qbits.
I think it is like a lot of things in their very early days, looks weird, difficult to grasp, nobody reckons on it, then suddenly a number of breakthroughs occur, and it is accepted commonplace. We'll see.
I read an article by some people who did research on quantum computing. It seemed that when using todays algorithms with quantum computers, the conventional computers would be faster. The only thing where quantum computers are now faster is things with rotation, like calculation an FFT. This is because quantum computing is about rotation, every particle has a certain spin, this is used.
Factorisation is a good use, but, it required 10,000 Qbits.
