Careful. Write down any quantum state you like: whether or not that state is entangled is a mathematical fact about the state (whether... -

New paper by Zeilinger, "violation of Bell Inequality with unentangled photons" https://arxiv.org/abs/2507.07756

Sambuco replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.As an aside, I'd like to mention something I think we've already discussed, but which is relevant to the current discussion. The...

Sambuco replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.The first time I read about collider loophole, I had the same reaction. Now, while when I'm not a "fan" of this idea, I have an opinion...

Sambuco replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.Hi everyone! A new paper by Wharton & Price was submitted to ArXiv ten days ago (https://arxiv.org/abs/2507.15128). There, they discuss...

Sambuco replied to the thread I The Extended Wigner's Friend Scenarios.If I understood the example correctly, Erwin plays the role of Wigner, right? In that case, Wigner is on the classical side of the...

Sambuco replied to the thread I The Extended Wigner's Friend Scenarios.When you say this, you are referring to the following post As I explained in post #17 and #18, that's not true, because the term AOE...

Sambuco replied to the thread I The Extended Wigner's Friend Scenarios.I'm not entirely sure what the objection is. If it is about the idea that decoherence can be reversed (at least in principle), that is...

That's a good question. It would be so if the reversal of the wave function was ideal, meaning that it is evolved with the Hamiltonian...

Sambuco replied to the thread I "Violation of the Equivalence Principle in Disk Galaxies" newly interpreted.On this point, there was a brief but interesting debate a couple of years ago. This paper (https://arxiv.org/abs/2303.11094) pointed out...

Sambuco replied to the thread I The Extended Wigner's Friend Scenarios.Good point! Perhaps @Demystifier can answer better, but if we reverse decoherence by making the wave function evolve "as if" it were...

Yes, universality is a crucial assumption in all those Wigner-friend thought experiments.
-
Sambuco replied to the thread I The Extended Wigner's Friend Scenarios.About what? About reversing decoherence? If so, in Bohmian mechanics there is a global wavefunction that never collapses, so it is...

Sambuco reacted to Demystifier's post in the thread I The Extended Wigner's Friend Scenarios with Like.
The review https://arxiv.org/abs/2308.16220 argues that, among the many extended Wigner-type thought experiments considered recently...

Sambuco replied to the thread I The Extended Wigner's Friend Scenarios.That's not entirely true. There are interpretations where decoherence can be reversed (at least in principle) for which AOE still holds...
