Jjavisot reacted to PeterDonis's post in the thread Graduate Entanglement swapping and Bohmian mechanics with
Like.
That's why I ruled out i); because it talks about the future swap causing the A/D correlation. As i) is phrased it says this creates the... -
Jjavisot reacted to Demystifier's post in the thread Graduate Entanglement swapping and Bohmian mechanics with Like.
This, in essence, is very simple. Consider a product state $$|\psi\rangle = |A\rangle |B\rangle$$ Any state can be written as a...

I agree, and I certainly agree that that's the position Bohmian mechanics takes, which is why I chose ii). :wink:

Jjavisot replied to the thread Graduate Entanglement swapping and Bohmian mechanics.It is an interpretation. "Never" and "always" are very big concepts.

There is no arrow of time in the microscopic regime. But the entanglement swapping involves measurements, and measurement is always a...

Jjavisot reacted to Ibix's post in the thread High School Einstein equations don't work at large scale? with Like.
Back in 1780, it was discovered that Newtonian gravity did not correctly predict the positions of the outer planets. Herschel proposed a...

This source does not meet the PF standards. So we can certainly discuss your questions, but we will not be relying on or discussing the...

Jjavisot replied to the thread Graduate Entanglement swapping and Bohmian mechanics.In the mesoscopic and macroscopic regimes, there appears to be a general arrow of time, but I do not know whether such an arrow exists...

Jjavisot reacted to Demystifier's post in the thread Graduate Entanglement swapping and Bohmian mechanics with Like.
The main issue is - can an event in the future cause another event in the past? I say it can't. Let me explain. The very notions of...

Jjavisot reacted to Roberto Pavani's post in the thread Graduate Entanglement swapping and Bohmian mechanics with Like.
Note that in the math order of measured doesn't matter as long as you keep bookeeping. This also agrees with what @javisot pointed out...

One possible item: I assumed in my previous posts that the operator ##U## realized by the Bell state analyzer was unitary. But it might...

But, as I think has already been noted, this implies backwards in time causation. Which means... ...this can't possibly be true, since...

Jjavisot reacted to Roberto Pavani's post in the thread Graduate Entanglement swapping and Bohmian mechanics with Like.
Standard entanglement-swapping setup: two Bell pairs ##|\Phi^+\rangle_{AB} \otimes |\Phi^+\rangle_{CD}## BSM on ##BC##, measurements on...

Since @Sambuco talks about electron-positron annihilation, I would like to draw his attention to the Hardy setup...

Jjavisot reacted to Matterwave's post in the thread Undergrad Spatial separation of entangled particles implies physical separability? with Like.
Are you reading the EPR paper? It was an implicit assumption of EPR that sufficient spatial separation implies non-interaction. They...
