Demystifier's latest activity

Demystifier replied to the thread I Is there any interpretation of QM that doesn't clash with intuition?.Bohmians do not have problems with probabilities, or with the view that nature is fundamentally non-deterministic. They have problems... -
Demystifier replied to the thread I Is there any interpretation of QM that doesn't clash with intuition?.Well, that's so in Newtonian gravity, which, presumably, you became familiar with before learning about special and general relativity...

Demystifier replied to the thread I Wigner's friend and quantum tunneling.Perhaps that's not really needed. Let me try to convince you in a few steps. 1. The reversion (undoing) of the measurement is not...
-
Demystifier replied to the thread I Wigner's friend and quantum tunneling.For that we would first need to agree on the general principles. For a start, do you accept the following principles? 1. Any physical...

Demystifier replied to the thread I Wigner's friend and quantum tunneling.I think you are missing the point of thought experiments. Their main point is to better understand the theory, not to learn something...
-
Demystifier replied to the thread I Wigner's friend and quantum tunneling.Well, that's a legitimate opinion, but as far as I can see nobody holds that opinion in the recent published literature on the extended...

Demystifier reacted to Sambuco's post in the thread I The Extended Wigner's Friend Scenarios with
Like.
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... -
Demystifier replied to the thread I The Extended Wigner's Friend Scenarios.I suspect we have different understandings of what AoE means. Can you explain it on some examples unrelated to quantum physics?

Demystifier reacted to Sambuco's post in the thread I The Extended Wigner's Friend Scenarios with Like.
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...
-
Demystifier replied to the thread I The Extended Wigner's Friend Scenarios.Because decoherence refers to the wave function (not to Bohmian particle positions and velocities), which in Bohmian mechanics is the...
-
Demystifier replied to the thread I Wigner's friend and quantum tunneling.Exactly. And yet, Schrodinger "cat" experiments are done in the laboratory. Not with animal cats, but with relatively big systems cooled...
-
Demystifier replied to the thread I The Extended Wigner's Friend Scenarios.I choose the former, I describe a system where the quantum state is reversed in practice, not just in theory: the spin precession of...

Demystifier reacted to PeroK's post in the thread I Wigner's friend and quantum tunneling with Like.
Would that apply to Schrodinger's cat as well? You cannot isolate the cat and the decoherence must leak out to the laboratory?
-
Demystifier replied to the thread I The Extended Wigner's Friend Scenarios.I disagree. In other interpretations of QM the results of all experiments are random, not determined by anything. By not controlling and...

Demystifier replied to the thread I Wigner's friend and quantum tunneling.The thought experiment assumes that you can. At least approximately, if not exactly.
