Ppines-demon replied to the thread I Commutation of operators for particle in a box.The potential is not a function that is differentiable in the usual way (at least not for the infinite well, for the finite well you...

Ppines-demon replied to the thread I Commutation of operators for particle in a box.Well usually ##[f(x),p]=i\hbar \partial f/\partial x ##, for a function ##f(x)##, but the potential here is kind of troublesome.

Ppines-demon reacted to phinds's post in the thread I Is there a bad intuition or bad explanation in quantum entanglement? with
Like.
QM is KNOWN to be incomplete, although not regarding entanglement (I make no argument either way on that) but rather because it cannot... -
Ppines-demon replied to the thread I Is there a bad intuition or bad explanation in quantum entanglement?.Here is a usual scheme for entanglement There are two entangled particles. Alice receives one of the particles, Bob receives the other...

Ppines-demon reacted to Demystifier's post in the thread Book recommendation after Sakurai Modern Quantum Physics with Like.
Maybe Atkinson and Johnson, Exercises in Quantum Field Theory. It's like a textbook written completely in the form of completely solved...

PThere was another raptor hiding in the bushes, just like in the film.
-
Ppines-demon replied to the thread Intro Physics Physics Introduction book.Use both. The more the better.

Ppines-demon reacted to PeroK's post in the thread I Quantum Entanglement and Synchronization with Like.
I guess your idea is to measure A and simultaneously B "changes state", which is instantly observed by clock B. That misunderstands...

Ppines-demon reacted to PeroK's post in the thread I Quantum Entanglement and Synchronization with Like.
The mechanism described there is not what you propose in your original post.
-
Ppines-demon replied to the thread I Quantum Entanglement and Synchronization.No, that would require faster than light signaling. This is not possible.
-
PDefinitely. I think I got the answer. A distinguished feature of QM is the quantization of quantities but usually this quantization...

Ppines-demon reacted to Morbert's post in the thread I Violation of Bell Inequality with unentangled photons with Like.
As an aside: When we write Bell states like $$\ket{\psi} = \frac{1}{\sqrt{2}}(\ket{\uparrow}_1\ket{\downarrow}_2 +...

Ppines-demon reacted to ohwilleke's post in the thread I Is Toponium a Reality Despite Top Quark's Rapid Decay? with Like.
The main discussion, after a lot of background for readers unfamiliar with the topic (the language in bold is the core substance of the...

Ppines-demon replied to the thread I Violation of Bell Inequality with unentangled photons.What about two electrons? Then you don't have issues because spins handle the symmetrization part.

Ppines-demon replied to the thread I Violation of Bell Inequality with unentangled photons.In my defense, this is not an isolated problem. The problem of Bell-testing the original EPR state has been discussed in research. Bell...
