Hi Ken. I've tried to read a little more about this whole thing to understand it better, and I think I've succeeded to some extent.
Regarding interventionist-based causality and its relationship to the common use of the cause-effect relationship even when no agents are involved, I borrow the...
I'm intrigued by what these "speculative metaphysical hypotheses" you're talking about are.
Without judging whether it's better or worse, I think this is because, in Bohmian mechanics, although the positions are hidden, something about them can be inferred from the measurements. For example, in...
As I mentioned in another thread, I have a similar suspicion to yours, in that I think the configuration of the system between measurements is too hidden, so to speak. In Bohmian mechanics, positions are hidden variables for those who measure, but not for the theory itself, since the position at...
Last week, two new papers by Barandes appeared about his unistochastic formulation: arxiv.2507.21192 and philpapers.BARADA-16.
The following excerpt is taken from one of them:
"From the perspective of this formulation, one sees that wave functions and the Schrödinger equation are secondary...
Thanks again for your detailed response! After reading it and rereading the article in Rev. Mod. Phys., I feel I understand the whole issue much better. Correct me if I'm wrong, but I think you're not trying to "reinterpret" conventional wavefunction-based QM or "reconstruct" the usual...
Thanks you for your detailed response! Now I think your proposal is clearer to me.
I may be wrong, but I see that in the community of foundations of quantum mechanics, "causation" is often used in a broader sense than that associated with an interventionist perspective. For example, if I turn...
Thanks Ken for joining us! :smile:
I would like to ask you about your perspective on the relationship between the concept of constrained colliders and the interpretation of quantum mechanics.
I see constrained colliders as a useful concept within information-based interpretations, such as...
I'm opening this thread to discuss entanglement swapping in the context of constrained colliders (the Price-Wharton proposal) and their relationship to retrocausality, and so that Ken Wharton himself can clarify some issues.

You don't understand that associating a quantum state with a particle is not the same as measuring it.
1. It's false that what you say is accepted in the community. QM textbooks (Zweibach, McIntyre) say you're wrong.
2. Again, Peres's quote, "unperformed experiments have no results," refers to...
No, that's not true. No one shared any references that support the position that "A forward-in-time analysis fails to reproduce the statistics of entanglement swapping experiments."
@DrChinese repeatedly argues about the different articles by the Zeilinger's group, but these have nothing to do...
As I explained in post #116, this is not interpretation-dependent. As the QM textbooks I've mentioned throughout this thread (Zweibach, McIntyre) explain, there is no other way to apply the measurement postulate when dealing with an entangled system that is consistent with experiments. The fact...
The question is valid under any interpretation, and the procedure for obtaining the answer is always the same. Let's see:
- Bohmian mechanics: How can I obtain the conditioned quantum state associated with particle 2 after the effective collapse induced by Alice's measurement on particle 1? By...
Yes, I'm reading you. Thanks for your answer :smile:
Now, I understand your objection much better. Let me address this with a simple example. A two-particle system is initially prepared in the state ##\ket{\Psi_{12}(t_0)} = \frac{1}{\sqrt{2}} (\ket{\uparrow_{1z}} \otimes \ket{\uparrow_{2z}} +...
Peter, please read me. I'm here because I enjoy debating about foundations of quantum mechanics in this forum. In this particular thread, I'm arguing about how different interpretations approach certain experiments and how this relate to retrocausality. In that context, I've said that...
