Isn't everything reversible if enough information is stored? Instead of COPY [A, B] -> [A, A]; you could have [A, B, 0] -> [A, A, B] which saves the value of B.

- ahakki 8y agoIIRC this is how you implement stuff, you always keep the inputs, so everything stays reversible.
- lisper 8y agoYes, but "keeping the inputs" is non-trivial in quantum-land because of the no-cloning theorem. You can't just make a copy of your inputs and stash them. You have to be more clever than that.
