gentzen replied to the thread I The Extended Wigner's Friend Scenarios.Neither Schrödinger, nor Wigner made that assumption. For both, sufficient personal testimony is available to known which points they...
-
gentzen replied to the thread I The Extended Wigner's Friend Scenarios.Let me remind you that this is a discussion about AoE and it relation to decoherence: Since AoE is true FAPP, decoherence cannot be...

gentzen replied to the thread I The Extended Wigner's Friend Scenarios.It is unclear to me why an example with a single electron should convince me that decoherence can be reversed in Bohmian mechanics.
-
gentzen replied to the thread I The Extended Wigner's Friend Scenarios.It certainly was not obvious to me. Overall, I found PeterDonis' arguments slightly more convincing than yours, but was still unsure...

gentzen reacted to PeterDonis's post in the thread I Wigner's friend and quantum tunneling with
Like.
Only if you isolate it from the rest of the universe. Which you can't. If nothing else, A+B are at finite temperature and are emitting... -
gentzen reacted to PeterDonis's post in the thread I The Extended Wigner's Friend Scenarios with Like.
Yes, it is, since the unobservable particle motions determine the results of all experiments in Bohmian mechanics. So to get the results...

Not of the friend and her laboratory. See below. Yes, and the way you described the measurement Wigner makes on the friend and her...

gentzen replied to the thread I QM Qubit state space representation by Projective Hilbert space.I am sure you know what you want, but you might miss some physics, if you ignore mixed states: I admit that capturing physics ignored...

please keep it simple, im a physics layman... when the friend inside the box keep looking at the electron, the electron is in a...

gentzen reacted to Demystifier's post in the thread I Wigner's friend and quantum tunneling with Like.
You seem to be talking about the quantum Zeno effect. If there is a measuring apparatus inside the box which causes the quantum Zeno...

And in post-modern understanding of QM, it's considered to be a reductio ad absurdum showing that objective facts don't exist. 🙃

Was this a prediction of the standard model or something new? If it was already a prediction, does the measurement put new constraints...

gentzen reacted to PeterDonis's post in the thread A Baryon CP Violation Observed at CERN with Like.
The LHCb collaboration has announced that they have observed CP violation in the decay of the beauty baryon. The Nature paper is here...
