I’m really just writing a post so I don’t forget how to do it. However, I have been getting interested in quantum computing (how does that work???) and consequently reading a beginners book on quantum theory, which isn’t much help to be honest.
So far, I think it has something to do with the principle of least action, reversible logic and goodness knows what else.
If I get work out anything useful, I will be sure to write it down. Don’t hold your breath though.
