Quantum computers have a tremendous potential capacity, their big problem in 
to keep their computing processing isolated from exterior effects and so 
protect their state superposition.

It has been pointed out (see: Mathematical Physics and Life, A. Patel, 
quant-ph/0202022 at arXiv on xxx.lanl.gov p.17) that enzymes work precisely 
by stabilizing a quantum state superposition between an initial and a final 
chemical product. So, why not use enzymes in a quantum computer?

The enzyme would have to shield from outer influences a rather big molecule, 
may be a DNA stretch able to hold many qubits, there is no natural enzyme 
able to do that, it would have to be specially produced. A computer must 
define the protected area shape then another software must find out the 
polypeptide sequence giving the right folding. Making the corresponding gene 
and including it in a bacterium is then a simple task.

I think the problem is with the computing power invested at start to define 
the enzyme, may be a distributed project could do it?...
