Like.
Just the time order of things as the paper presents it. T is not the time of the measurement, it's the final time after which the... -
bhobba replied to the thread Undergrad Spatial separation of entangled particles implies physical separability?.Wait a minute, if I remember correctly, EPR concerns that if you measure position or momentum, you can immediately predict the position...

EPR made an implicit assumption in their argument that indeed you can stop the two particles from interacting with each other...

bhobba replied to the thread Undergrad Spatial separation of entangled particles implies physical separability?.The general principle is that in QM the outcome is the eigenvector of the observable. Here it is a product state of 2 separate single...

Hmmm, what are you counting as a "single excitation" here? If you hit the state with the number operator, you don't get 2?

You do get 2, but you can't split the state up into a product of two states each with a value 1 for the number operator. That's what it...

Love.
Please be aware that according to the rules of this subforum, claims that a particular interpretation of QM is wrong (or right, for that... -

Yes: it adds the actual position and velocity of each particle. But it also changes how the wave function, which is also present in...

@PeterDonis you are right, the word "spurious" was not appropriate.

bhobba reacted to PeterDonis's post in the thread Graduate Entanglement swapping and Bohmian mechanics with Love.
Is the word "spurious" really justified here? After all, when B and C come together just before ##t_2##, B is entangled with the A...

If you are carrying out the textbook standard QM calculation of unitary evolution -> measurement -> collapse (preparation) -> unitary...

The point is not just that they are gone, but also the measuremnt on A and D happens before that on B and C. Is it action in the past...

In the other thread, @DrChinese says: "Show me any Bohmian step by step explanation of the mechanics - in precise time order as required...

If particles no longer exist, then something else absorbed their energy, momentum and quantum information. For example, a photon is...
