How is information defined when considering locality in quantum mechanics?
$\newcommand{\ket}[1]{|#1\rangle}$
My question is a follow-up from this discussion about the presence of non-local correlations in a theory that is deemed local. The first answer talks about the ...

How did the local hidden variable theory resolve the EPR paradox?
I'm trying to understand the motivation for local hidden variable theory. The EPR paradox considers the following thought experiment, where we can express a state $|\psi \rangle \in H_{Alice} \otimes ...

Many Worlds locality and EPR experiment
I've read in Sean Carroll's book (Something Deeply Hidden) that the Many-Worlds interpretation of quantum mechanics might be the only way to avoid instantaneous effects of entanglement, by having the ...

Reality, locality, and universality in the EPR paradox
Apologies if this has been asked before. I did some searching but didn't see it anywhere asked quite like this. Thanks in advance for any insights.
Caveat: I am an organic chemist and thus ...

Distinguish Definitions: Realism Scientific, Realism, and realistic
I was readying about study about bell's theorem, where I had the question about some definitions.
Here's some of my summaries:
Scientific Realism:

Shouldn't local realism imply the superdeterminism?
I see that Bell has ruled out Einstein's local realism but not supredeterminism. I see that Bell has confessed that superdeterminism kills his inequality. You cannot apply Bell's inequality if ...

How is locality preserved in quantum mechanics?
I was reading this post:
http://motls.blogspot.com/2015/06/locality-nonlocality-and-anti-quantum.html
Specifically here: "There is no nonlocality. There is no action at a distance. There is no doubt ...

Does the many worlds interpretation eliminate the spooky action at a distance paradox? [closed]
I'm sorry if this is a stupid question. I'm a novice at physics.
I have read the article about entanglement and EPR paradox. The spin of two particles is measured when they are very far apart, and ...

Why does a violation of locality not imply a violation of relativity?
This question is closely related to: What counts as information?
Taking the specific example, again, of the EPR experiment. I think everyone agrees on the following:
The act of measuring the ...

Bell's theorem for dummies, how does it work?
I've been reading up on theoretical physics for a few years now and I feel like I am starting to get an understanding of particle physics, at least as much as you can from Wikipedia pages. One thing ...

Tracking down the locality assumption in a CHSH inequality derivation
CHSH inequality requires both locality and realism. I will equate here realism with counterfactual definiteness.
Now counterfactual definiteness tells us that given two different measurements on the ...

Relativity and Entanglement
Say we have two particles which are entangled so that they have opposite spins. If one is up, the other is down. They are sent off to two spatially separated observers A and B. Both observers can ...
