I was thinking of a physical substrate, perhaps something comparable to the process of forming fossils. In whatever mud it is, successful proteins lay themselves down like fossils, and the presence of that fossil acts as a template to produce similar proteins. Perhaps two of these "fossils", laid accidentally end to end, could result in the production of a third, more complex protein. I haven't seen this quantum information processing idea before. But yes, it's interesting. It does invite this question though. (Anyone one wishing to understand the question will need to read the link. It doesn't take long.) With regard to its increasing the speed of complex protein folding, why would quantum information processing favour one type of folding over another?
