transform keeps tensor structure

[chrisgee]

I understand that basis transforms are in development. But I saw one thing that might be worth considering:

The dims propery of property is unaffected by doing a transform even though nothing guerantees that the product structure remains. Partial traces become meaningless (unless the origin of that structure is kept).

Either one has to keep a copy of the transform in the transformed object to still be able to trace out factors or the resulting object has to become unfactorizable...

... I think...

This seems an issue for the qutip/qutip repository.

@chrisgee yes please can you reopen on qutip/qutip. This seems like an interesting question.

I understand that basis transforms are in development.

Do we know who is doing this?
