Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?."After passing through the PBS, the photons are rotated by HWPs to the |p/m〉 = 1√2 (|h〉 ± |v〉) polariza- tion basis. For reasons of... -
Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.If they are initial states, then you do not get entanglement swapping. If they are not initial states, you get entanglement swapping. I...

Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.You're misinterpreting these states as initial states. These states as initial states cannot lead to entanglement swapping however it is...

Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.I am saying that, in Megedish's experiment, the rotation of indistinguishable particles (interference terms) vs the rotation of...

Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.I do not dispute any experimental facts. Everything I have said is fully consistent with Ma's paper. What I dispute is your incorrect...

Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.As an aside, forward-in-time accounts based on ordinary undergraduate-level formalisms of QM are perfectly capable of reproducing all...

Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.In both the Ma and Megidish experiment, the state of the biparticle system incident on Charles's apparatus is rotated during a...

Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.Classical examples are not used to explain Bell inequality violations. They are instead used to draw analogies in causal relations: In...

Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.We can construct similar statements for classical systems. In the past I have used Bertlemann's socks scenarios. Price + Wharton use a...

Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.It would be: If we assume retrocausality is possible, then there is no sensitivity of the CL to the spacetime location of the central...

Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.To invoke retrocausality in the manner it is invoked by Price + Wharton in the OP, all that is necessary is the preparation events of...

Morbert replied to the thread I Entanglement: is there 'action at a distance' due to measurement?.A principles-based understanding of a physical theory is desirable, but I don't think it dissolves interpretational disputes. Even in...

Morbert replied to the thread A Challenge to Bohmian mechanics by Sharoglazova et al, Nature, 2025.It was not used as a reference in this discussion. It was an aside, showing the issue had reached popularizers. Sabine's videos are...
