Ppines-demon replied to the thread I Violation of Bell Inequality with unentangled photons.Take some state like ##|\psi\rangle=\int \mathrm d x\, |x\rangle|-x\rangle## (if you are worried that this is not normalized correctly...
-
Ppines-demon replied to the thread I Violation of Bell Inequality with unentangled photons.What is the issue? There are Bell inequalities for continuous variables or you can discretize your space. I mean you measure the...

Ppines-demon replied to the thread I Violation of Bell Inequality with unentangled photons.why not?
-
Ppines-demon replied to the thread Predictions for the Nobel Prize in Physics 2025.Topological qubits do not exist yet, Microsoft released a fake topological qubit in 2025, but they are not sure if it is topological and...
-
Ppines-demon replied to the thread Predictions for the Nobel Prize in Physics 2025.I started the topic, because the first predictions are in. Domenico Fuoco from Polytechnique Montréal wrote a paper "How To Predict The...
-
Ppines-demon posted the thread Predictions for the Nobel Prize in Physics 2025 in General Discussion.Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a...

Ppines-demon reacted to Ibix's post in the thread I Can this experiment break Lorentz symmetry? with
Like.
But the results won't be exactly symmetric due to experimental error. So how big a deviation can you tolerate? To answer that question... -
Ppines-demon reacted to PeroK's post in the thread I Can this experiment break Lorentz symmetry? with Like.
Researchers into quantum gravity are not going to change course because a student somewhere is mixing up classical physics and relativity!

Ppines-demon reacted to sbrothy's post in the thread History Biographies, History, Philosophy of Physics with Like.
Triggered by this thread: RIP Rainer Weiss (1932-2025) arXiv: DEDICATED TO COSMOLOGY AND GRAVITATION - AS TOLD BY RAINER WEISS

Ppines-demon replied to the thread I Violation of Bell Inequality with unentangled photons.I was under the impression that it did not but I could not figure it out from the original paper. Wharton pre-print above says it is...

Ppines-demon reacted to PeterDonis's post in the thread I Violation of Bell Inequality with unentangled photons with
Informative.
It meets the standard definition of entanglement, correct? The joint state of the two particles can't be factorized into a product of... -
Ppines-demon reacted to martinbn's post in the thread I Violation of Bell Inequality with unentangled photons with Like.
What is indistiguishable here, the photons or something else?
-
Ppines-demon replied to the thread I Violation of Bell Inequality with unentangled photons.If this experiment holds it looks like a competitor to DrChinese's entanglement swapping arguments :oldbiggrin:

Ppines-demon reacted to chimay's post in the thread Solid State Ashcroft and Mermin: revised edition with Like.
Hi, I have notice that Ashcroft, Mermin and Wei worked at a revised edition of the original solid state physics book (here). The book...
