Like.
I would say... unlike bell HV, which correlates STATES via objective beables of which we are just ignorant; so we marginalize over them... -
iste reacted to Morbert's post in the thread Graduate Understanding Barandes' microscopic theory of causality with Like.
The latter Zeilinger paper maps nicely onto section VIII of Barandes's new prospects paper. We have 7 subsystems: particles 1,2,3,4...

iste replied to the thread Graduate Understanding Barandes' microscopic theory of causality.Just a thought: in his arxiv:2402 paper, it looks like Baranded implies that the subject systems (not measuring devices) do nonlocally...

iste replied to the thread Graduate Understanding Barandes' microscopic theory of causality.Signalling in terms of the evolution of particles' Markovian trajectories is the stochastic mechanical manifestation of Bohmian nonlocal...
-
iste replied to the thread Graduate Understanding Barandes' microscopic theory of causality.Its informative in one rather niche sense that he views his theory as a hidden-variable interpretation. The two major hiden variable...

yes, and a very poor one in most cases, except when a system is nearly in the ground state (as for molecules in much of quantum...

iste replied to the thread Undergrad Valid local explanation of Bell violations? (Pegg et al., 1999; 2008).Its not the quantum state at preparation but they are still evolving a quantum state backward in time from measurement. They are doing...

iste replied to the thread Undergrad Valid local explanation of Bell violations? (Pegg et al., 1999; 2008).They are evolving a quantum state backward from the measurement. They are using quantum theory and just exploiting that it seems to work...

iste replied to the thread Undergrad Valid local explanation of Bell violations? (Pegg et al., 1999; 2008).I will give my take here on why it is not obvious that the backpropagation is "time-travel", connected to the fact that the quantum...

iste replied to the thread Undergrad Valid local explanation of Bell violations? (Pegg et al., 1999; 2008).I don't think so. Its related to Bayes' theorem about probabilities so I can't see this as making any presumption about determinism...

iste replied to the thread Undergrad Valid local explanation of Bell violations? (Pegg et al., 1999; 2008).If it relies on information going backward-in-time, it doesn't rely on the other spatially separated measurement in a manner which is...
-
iste replied to the thread Undergrad Valid local explanation of Bell violations? (Pegg et al., 1999; 2008).The description used in the papers is done exclusively with quantum theory, so I think what it comes down to is whether backward...
-
iste replied to the thread Undergrad Valid local explanation of Bell violations? (Pegg et al., 1999; 2008).Maybe, but I think that if this retrodiction is problematic, you have to ask why it seems to exist as an option in quantum theory in the...

iste replied to the thread Undergrad Valid local explanation of Bell violations? (Pegg et al., 1999; 2008).I think it does though because the explanation only relies on a random measurement outcome and what that retrodicts backward-in-time in...
