Alternative formalization of quantum mechanics?

Hi, friends!

I know there are some alternative formalization of quantum mechanics, which give non-Copenhagen explanation. For example, Bohmian formalization give an explanation of global determinism.

Currently, I would like to know whether there is an alternative formalization, which supposes that the entanglement exist among observers (or measurement devices)? Thanks a lot for any information and advices.

Bohm is an interpretation, not an alternate formalism. There is really only one formalism.

The transactional interpretation is rather good at dealing with observers, but at the cost of traveling in time.
