Quantum CVS

In a previous post, I had asked for emacs-based approaches to tracking changes in a document. There were many useful suggestions, some of which I might actually try out. The most promising is also the most intriguing. It is called darcs:

Darcs is [..] based on a "theory of patches" with roots in quantum mechanics

There's more.

I have looked at patches as being analogous to the operators of quantum mechanics. I include in this appendix footnotes explaining the theory of patches in terms of the theory of quantum mechanics.

Takes quantum computing to a new level....

I should add that the patch software itself appears quite reasonable, and in fact came highly recommended in the comments to my prior post. The main connection to QM appears to be the fact that patch operations are reversible (there is also some stuff about commutativity of patch operators).
