"he basically said that the idea of quantum computing is based on a fundamental misunderstanding and cannot work"
I always wondered how you can get a result if there are the thing is always true and false at the same time.

John Kerry may be able to answer that.
Quantum mechanics is a very different way of thinking about how stuff works.
Rather than a bit being 100% 'true' or 100% 'false', the bit has an X% chance of being 'true' and (1-X)% chance of being 'false'. Bizzare, but that's what real physics does on a really small scale.
Start with that strange way of thinking about things, and compound multiple bits - just as modern computers start with a 'true/false' bit, and compound things from there.
Until you observe it; then its either one or the other.
You have to get beyond 3 dimensions to get that to work...
