I don't know much about this, but I think the case may be different for
Quantum computing. The last chapter of Simon Singh's book "The Code Book"
anticipates quantum computing & suggests that such devices might be able to
crack existing public key/private key encryption devices. To do so one has
to find two very large prime factors of an enormous composite number. I
believe the implication was that the factorization might be doable as all
divisors could be tested simultaneously in a superposition of quantum
states. But I don't know whether this is just a SciFi type fantasy at the
moment or whether it actually is a practical possibility. I don't think
anyone's seriously suggested biological evolution as being a large scale
quantum interference effect, though. How's that for a crazy idea?

I guess so; I suppose you could make the analogy between such systems (ID +
added components) and pure ID as being analogous to composite numbers and
I'll leave the biochemists to answer your other question.
