Again, you deny the obvious. And of course not, I don't believe the system has to be in an eigenstate of the observable before measuring that observable begins. It is laughable you concluded this from any of my posts. I clearly said many times the state COLLAPSES onto an eigenstate upon...
Please try to not comment on non-physics issues. Fredrik, come on, I was being totally nice.
As a last note, I have said all I said in this thread, and thank you all for a nice discussion that showed me why I love quantum mechanics so much. This is my last entry on here. All of you take...
It is not written in law that the MZ interferometer has to use two detectors. One is enough. Read below.
Like I mentioned, this is experimentally really, really well established that you can prepare photons in the same polarization state and with the same frequency over and over again. As...
Fredrik, I'm sorry if I have insulted you. I clearly stated before I have respect for you. I don't dislike you and I don't mean to offend you. Let's move on.
However, I'm not the only one who thinks you have made statements at odds with standard QM. And it's very improbable that more than...
Yes there is, it's called technology. The sky does it, preparing photons with the same polarized state with the same frequency (blue) at a 90-degree angle with the sun. Surely we can do it, and much better.
I don't know much about Bohmian mechanics except that it is experimentally very...
This is what I mean that you ignore my rebuttals that you can't refute. I will say it here again, Fredrik.
The number operator \hat{N} is that when you have a two-site lattice where you trap a number of atoms, where this site is described by the state |\psi\rangle = |n_l,n_r\rangle, then...
I'm tired of arguing with you about semantics. It seems to me you keep using semantics to cover your mistakes in physics.
This is trivial. There's no reason to believe one cannot prepare the same photon over and over again. Moreover, you need this in order to find out in any measurement...
Yes, but this is better stated as observation has something to do with the Heisenberg Uncertainty Principle rather than the Heisenberg Uncertainty Principle has something to do with observation. It is the nature of things, embedded in the HUP, that makes observation the way it is, and not the...
It indeed has nothing to do with observation in the sense that you do not need to observe for the HUP to hold. You keep dodging this. What effect does observation have to do with the HUP? Please explain it to me. What does observation have to do with the relation
\langle (\Delta...
Fredrik, I was aggressive with you as much as you've been with me. And no, we don't agree on everything. Cohen-Tannoudji and Sakurai (if the latter was alive) would agree with me unless their books are wrong. Theirs are my quantum mechanics bibles. Anyway, read the post I made, it is 2...
OK I decided to answer this quickly, but next time ask in a more polite way ;). Moreover, I think this is something many were keen about here because Fredrik's propaganda machine had wrongly (yet again) made people on here think you can't measure momentum unless you measure position (I don't...
This is what made me think it was unclear to you. You obviously (from your request) seem to not be familiar with how interferometry on a single photon works. This makes me conclude that it is not familiar to you to see single-photon interference akin to many-photon interference, hence my...
That was actually me and there *are* people who talk to ghosts (just kidding).
You accuse me of reading comprehension issues and I think I only proved that I understand things quite fast by understanding the general meaning of the paper you posted (now of course you will deny that). But keep...
