gentzen replied to the thread I Is there any interpretation of QM that doesn't clash with intuition?.Well, that depends on the version of Copenhagen. Bohr's version is inherently non-relativistic. The version by Heisenberg and his...

gentzen replied to the thread I Can entanglement swapping be explained without nonlocal influences?.But how should I know what counts as an explanation for you? How should philosophy help, if everybody decides for himself anyway, which...

gentzen reacted to PeroK's post in the thread I Can entanglement swapping be explained without nonlocal influences? with
Like.
When I studied pure mathematics, I had to retrain my intuition and change my intellectual expectations of what mathematics was about... -
gentzen replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.You mean "yes"? The protocol for quantum teleportation would require you to apply 1 of 4 different unitary transformations (one of them...
-
gentzen replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.You replied to "... the statistical data are predicted by the forward-in-time evolution ..." which mentioned both MWI and Bohmian...
-
gentzen replied to the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”?.Let me remind you that the current consensus is that Bohmian mechanics makes the same measurable predictions as orthodox...

gentzen reacted to Morbert's post in the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”? with Like.
As an aside, forward-in-time accounts based on ordinary undergraduate-level formalisms of QM are perfectly capable of reproducing all...
-
gentzen replied to the thread I Is there any interpretation of QM that doesn't clash with intuition?.So you think Wolfgang Pauli made a mistake, when he admitted that Bohmian mechanics is not contradictory? I still want to dig-out...

gentzen reacted to Demystifier's post in the thread I Is there any interpretation of QM that doesn't clash with intuition? with Like.
Well, that's so in Newtonian gravity, which, presumably, you became familiar with before learning about special and general relativity...
-
gentzen replied to the thread I About concept of wave-particle duality.That is a math question, independent of QM/QFT. There never was much connection between wavelets and wave-particle duality. (The...
-
gentzen reacted to JimWhoKnew's post in the thread I Phase and group velocity for the wave function with Like.
The group velocity is often motivated (and justified) by the stationary phase approach. It goes something like this: Consider a wave...
-
gentzen replied to the thread I Wigner's friend and quantum tunneling.Yes, for your purposes. There is no relevant distinction between macroscopic and microscopic system. (When a physical system has the...
-
gentzen replied to the thread I Wigner's friend and quantum tunneling.I am still waiting for a convincing argument that the experiment can be done in principle. My "This starts to get ridiculous" reaction...
-
gentzen replied to the thread I Wigner's friend and quantum tunneling.Initially, it looked like certain kinds of experiments would be possible for small systems. But then came [...], which caused my...
-
gentzen replied to the thread I The Extended Wigner's Friend Scenarios.Let me repeat my old example cited in my reply to Sambuco: If you have a time machine, then "observed events" are not necessarily...
