Morbert replied to the thread I Can entanglement swapping be explained without nonlocal influences?.In discussions of instrumentalism, questions like "What is a measurement?", "What counts as a measurement apparatus?", "Where is the... -
Morbert replied to the thread I Can entanglement swapping be explained without nonlocal influences?.Chapter 12 of Asher Peres's "Quantum Theory: Concepts and Methods" gives a concrete account of measurement from a modern instrumentalist...

The question is valid under any interpretation, and the procedure for obtaining the answer is always the same. Let's see: - Bohmian... -

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...

As I explained in post #116, this is not interpretation-dependent. As the QM textbooks I've mentioned throughout this thread (Zweibach...

No, that's not true. No one shared any references that support the position that "A forward-in-time analysis fails to reproduce the...

Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.Have Ma or Zeilinger ever commented on the different interpretations of their experiments? This is not a rhetorical question. I am...

Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.The von Neumann projection postulate does not carve out exceptions for entangled systems. So long as the measurements are projective, an...

Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.A and B are entangled, and hence in an inseperable state, so a projective measurement on A projects the entire system onto a new state...

Yes, I'm reading you. Thanks for your answer :smile: Now, I understand your objection much better. Let me address this with a simple...

Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?."For successive, non-destructive projective measurements with discrete results, each measurement with measuring value can be regarded as...

No! I'm not saying that. In fact, I don't believe that these operations have a physical meaning in the sense of action-at-a-distance or...

Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.I did not make anything up. I applied basic quantum mechanics to compute probabilities for possible sequences of measurement outcomes...

Morbert replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.There is absolutely a difference between the rotation of distinguishable vs rotation of indistinguishable particles. You cannot...
