No. The operationalis/instrumentalist account is probabilistic and has no objective collapse. Consistent histories is probabilistic and...

That's true, but cases ii and iii correspond to situations where Alice and Bob enter their respective laboratories and ask Charlie and...

I still need to read the paper properly to give a proper response, but in the AOE section they have "ii. P(a|cd,...)" and "iii...

I'm not sure what you mean by this but I don't think I agree, and it would take us too far into philosophy for my comfort.

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...
