The only relevance systems that partition into a measured system and a measurement device/environment have is they are the systems we...

Remember though that in this formalism, the configuration a system or subsystem is in is not indexed to any observer. In which case if...

I don't see how the bit in bold is true if dynamics are non-Markovian. [edit] - I.e.: AOE + Markovian dynamics = joint probability...

@Sambuco Re/ Wigner's friend:

I am not sure what GSC is. Do you mean GSS (generalized stochastic system)? What Barandes shows is that we can associate any quantum...

This stochastic formalism rejects everywhere-divisible dynamics, something Bong et al don't consider. This is perfectly reasonable...

Honestly, I'm not, as it is what connects a mathematical result to a physical interpretation. It's what lets you regard a quantum system...

@iste One reason this discussion has gone on for so long is I wasn't sure I fully understood your concern. But now I'm pretty sure I do...

Barandes does indeed observe in arXiv:2309.03085 that a stochastic process ##(\chi,\mathcal{T},p,\mathcal{A})## is more general than a...

I will have to admit my knowledge of the LF no-go theorem is minimal, so my response will be from the hip. From the paper: The...

To clarify, I understand "take something like spin and translate it into a generalized stochastic process" in two ways. i) Translate it...

I would like to hone in on this for a moment: Barandes presents a model of a generalized stochastic system as a tuple of the form...

The configuration space provides the kinematics as per the first axiom. As such there is no ambiguity or need for a measurement context...

Yes, and there is no tension between the non-interventionist account arXiv:2402.16935 and interventionist accounts so long as you are...

The classical configuration space is not inherently a measurement basis. It is a space of definite arrangements the system can be in...
