> anyone got any thoughts on quantum computing? seems like it be revolutionary in medicine

QC is a hype.

But better stuff is coming and on-going

The arguments against QC seem centered around the problem of decoherence

No, it is about number of observations needed to confirm the coherence. That's why cooling is important, but still reduction of statistical error remains main issue.

@nikol have you read quantum computation and quantum information?

Yes, of course. Sorry, 'decoherence' is exactly what I meant. You are right.
All this is reduced to the very simple fact: measurement process destroys information about single quantum state. (see my previous statement)

I recommend this book:
"Dynamics and information", by Kadomtsev

The Einstein–Podolsky–Rosen paradox is discussed in detail together with its possible role in the processes of information transfer over a distance

Russian version is bigger, but the above excerpt in English is quite good.
