Off diagonal #383

nquesada · 2024-02-15T03:10:05Z

A somewhat more numerically stable coherence calculation of the density matrix.

I've looked through the changes and to me this all looks great, though I would be much happier if @rachelchadwick has a good look through too. Personally I'm happy to approve, pending the 1 failing test.

Nice @nquesada ! I am still going through the finer details but I've left some comments/suggestions below. One general suggestion is to try to find a way of giving a warning when the recursive method is not correct. It would be nice to be able to use the recursive when it's correct and the non-recursive (ie slower) only when needed, but we have no easy way of knowing when it's working. Could we do some sanity checks like the diagonals are all >0 and <1 and the sum of them is getting closer to 1 as we increase cutoff? Not too sure how to check the off-diagonals. If you're happy with any suggestions but don't have time to implement them, let me know and I can always implement them.

Can we just use the fact from .utils or is there something different?

Now it is just factorial from scipy.special

But why not use the stored factorials from utils to avoid recalculating like we do in _density_matrix_single_mode?

Yup, good point.

@rachelchadwick this worked! Looking fwd to see this branch merged!

@nquesada But it seems to fail with a segmentation fault most of the time. That's not something I want to merge into main for sure.

This reverts commit 0f99b20.

rachelchadwick · 2024-04-30T22:16:33Z

Ok I've run it several times now with no problem so the segmentation error seems to have fixed itself too. So unless there are any objections I'll merge this one into internal_modes tomorrow.
