The more I think about this, the more surprised I am. I'm not a professional physicist, but I was under the impression that there were already ways to let the state vector evolve through multiple events without forcing a collapse.

This is nice. Obviously the state vector evolves continuously, since we observe multi-step quantum processes. It is nice to have a theory that can handle it.

Yeah, I'm really excited about this actually.

The Born rule is a current postulate of quantum mechanics that tells you how a wave function relates to the probability of seeing certain outcomes when performing a measurement. The wave function collapse is another current postulate of quantum mechanics that tells you what will happen to the wave function after performing a measurement. This new rule is apparently a newly proposed postulate from which the Born rule and the wave function collapse can be derived.

Disclaimer: I haven't read the actual paper yet, so just going off the media blurb and the abstract here.

Importantly the Born rule does not require the axiom of separability, unfortunately it is still debatable to require locality, or at the least, the conditional Bayesianism, of some given network.

A lack of separability makes sense, from the perspective of entanglement. Bayesianism, may still possess paradoxes, or at the least, incomplete information can lead to a need to update. One could argue the need for paraconsistency, if there is a violation of realism, over a violation locality. Of course if the network is feed-forward, who says surrealism interprets?

There are other methods which have both hermicity, non-hermicity, and completeness. Dual and nondual.
