Quantum entanglement is the mechanism by which quantum correlations between two sub-systems survive even after being physically separated from an interaction region. The correlations could in principle survive without neither time nor space constraint.

Quantum entanglement and space like separation of entangled particles
Suppose we have 2 entangled particles who are not in the light cone of each other(they are space-like separated).Suppose that you have a observer named Earth who is inside the lightcones of both ...

Entanglement and Conservation laws - switch the hierarchy [closed]
I see in this site clear refutations of the idea that entanglement is due to conservation laws. However, what about flipping the question: Are conservation laws a subsystem or an example of ...

Could "observation" or "measurement" be considered another dimension of our universe? [closed]
I hope you'll pardon my use of imprecise language ahead of time; this is just an idea that I had, but I haven't had the time/energy yet to try to flesh it out much with some proper mathing.
So, as we ...

Can the EPR experiment be explained classically by treating space time as its own object? [closed]
This question is based on arguments presented in this blog post by Richard Carrier.
From the blog,
It's thesis: quantum entanglement phenomena, as exemplified in any form of the EPR experiment, can ...

What does ER=EPR actually mean? Is entanglement really the same as a wormhole?
I’ve been trying to wrap my head around the ER=EPR idea that Maldacena and Susskind proposed — the claim that entangled particles (EPR pairs) might be connected by tiny wormholes (ER bridges). On the ...

Can simultaneity of two events follow the following pattern [closed]
I wasn't sure how else to phrase the title of this question, someone is welcome to try for a better title.
If I have two events taking place that are far apart in space. Assuming from the frame of ...

How to generate a random separable state?
Let's say we have two Hilbert spaces $\mathcal{H}_A$ and $\mathcal{H}_B$, of dimensions $d_A$ and $d_B$ respectively. Then we know that a separable state acting on the Hilbert space $\mathcal{H}_A \...

A small black hole about to evaporate inside another black hole, what effect on entanglement and firewall idea?
Scenario Recap:
A small black hole (near evaporation) falls inside a larger black hole.
The small one would normally evaporate via Hawking radiation and its quantum entanglement structure is critical ...

Can Quantum entanglement be verified on the Moon? [closed]
Has quantum entanglement been verified say by seeing if a measurement of a Quantum bit on Earth is the same as on the Moon, to be verified? Just curious if such a project would be viable for science ...

How can a non-entangled quantum state be created?
In quantum mechanics, the process of decoherence causes interference to disappear. As explained by Schlosshauer, decoherence occurs when a quantum state becomes entangled with the environment.
Naively,...
