gentzen replied to the thread I Violation of Bell Inequality with unentangled photons.The issue is that your answer doesn't help me to see how the entangled particles can be used for Bell's inequality violations. What do...

gentzen replied to the thread I Violation of Bell Inequality with unentangled photons.If you look at the actual combined state of the two subsystem that may be entangled, then you often end up with a density matrix instead...

gentzen reacted to martinbn's post in the thread I Violation of Bell Inequality with unentangled photons with
Agree.
Doesn't this depend on which degrees of freedom you use? If you choose two random photons and ignore all but their polarizations, they... -
gentzen reacted to Demystifier's post in the thread I Violation of Bell Inequality with unentangled photons with
Like.
The effect is explained in the paper by quantum indistinguishability. But indistinguishability in QM is implemented by symmetrization of... -
gentzen reacted to Demystifier's post in the thread I Violation of Bell Inequality with unentangled photons with Like.
Also note that even the QED vacuum, i.e., a state with zero number of photons, is highly entangled. Hence it is really impossible to...

Your name here, renormalize, holds the key, as I think you probably know. In QFT, early on, there was a deep problem. We kept getting...

gentzen replied to the thread I Modern View of Quantum Phenomena.I read that method section now. Obviously, you didn‘t understand my remark, or what I would like to measure. This makes me wonder...
-
gentzen replied to the thread I Modern View of Quantum Phenomena.I upvoted this, because I didn't realize it before. This raised the question for me, what we actually measure in spin measurement, if...
-
No, they don't. They're not a group in 3+1 spacetime; they're not closed under composition. Only in 1+1 spacetime do Lorentz boosts by...

gentzen replied to the thread I Physicists disagree wildly on what quantum mechanics says about real….Asher Peres (1978) Unperformed experiments have no results. Rudolf Peierls (1991) In defense of „measurement“.

Everyone requires different experiences to "understand" something; the term means different things to different people. Physicists...

gentzen replied to the thread I Modern View of Quantum Phenomena.Do you believe that you can communicate your "realization" to me (or PeterDonis, or PeroK, or ...)? Do you believe that I would get...

gentzen reacted to Lord Jestocost's post in the thread I Physicists disagree wildly on what quantum mechanics says about real… with Like.
There's no need to complicate things. Marian O. Scully, Berthold-Georg Englert and Herbert Walther have captured the essence of the...

gentzen replied to the thread I Physicists disagree wildly on what quantum mechanics says about real….Hey, I was honestly proud that I seemed to have found an interpretation of "that specific quote of Bohr's words from Don Howard's paper"...

gentzen replied to the thread I Physicists disagree wildly on what quantum mechanics says about real….Maybe the trick to understand Bohr would be to focus on his discussions with other physicists and scientists, instead of trying to make...
