PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.Unfortunately, after looking at this, it doesn't tell us what we need to know. This evolution starts with the two distinguishable Bell... -
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.Can you be more specific? -
PeterDonis reacted to Matterwave's post in the thread Undergrad Spatial separation of entangled particles implies physical separability? with
Like.
By "independence" here, do you mean statistical independence of measurements? In analyzing an argument such as EPRs, it is best if we... -
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.This might be one of those cases where we have to be very careful about distinguishing two different cases, which intuitively "look the... -
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.Yes, and something more like my post #76, where I described what my account would look like for a setup in which all four Bell states... -
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.But, as I think has already been noted, this implies backwards in time causation. Which means... ...this can't possibly be true, since... -
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.I agree that, given the various complications that have been discussed in subsequent posts (some of which you allude to), saying "a swap... -
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.I think this is somewhat too strong. Consider this from a previous post of mine: Generalizing on this: for a swap into the ##\Phi^\pm##... -
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.Yes, as @Morbert pointed out, what I was calling my "bucket 1" is not really "swap attempted but no swap", but "swap that the... -

1. I think "implies" is fair. 2. I would certainly include any automated "auxiliary random process" as being an expression of the... -
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.The Hilbert space doesn't change just because you make a measurement or perform a unitary operation. The full Hilbert space describing... -
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.Ah, I see. So my buckets 0 and 1 will not show the same statistics. For an interpretation with actual collapse, yes. But we are using... -
PeterDonis reacted to Dale's post in the thread High School Einstein equations don't work at large scale? with
Like.
This is a very important point in understanding how science actually works. Popper popularized the idea of falsification, but... -
PeterDonis reacted to Dale's post in the thread High School I don't understand the Michelson–Morley experiment with
Like.
Probably it is best to not hijack your own thread. You already have another thread in this topic... -
PeterDonis replied to the thread High School Einstein equations don't work at large scale?.Not "wrong", no. It is a valid approximation to GR in the regime where gravity is weak and all relative speeds are small compared to the...
