As I mentioned, albeit with some vociferousness, in another article's comment area, we ~DO~ get to vote on what reality is.
If one takes QM and superimposes it and it's interface with the classical, they will find the signature of this in ALL of the well done parapsychological works that are out there. Which there are many thousands of studies, all done with the rigor any determinist would be proud of and expect at a minimum (and beyond).
The results of those works show that determinism functions in world of information as a quantum field that is shaped by collectives of energy.
It's quite amazing how little I understand of all this. But does anyone actually know how entanglement is possible?It appears to be a law of quantum physics, driven by Heisenberg uncertainty and conservation laws. Asking how it's possible is like asking how gravity is possible, or how Newton's Laws of Motion are possible. There is no underlying explanation. It is what it is, and it is what is observed.
And what constitutes such QM information transfer?There is no apparent information transfer. That would violate Special Relativity Theory.
no underlying explanation. It is what it is, and it is what is observed.I don't think we have stopped asking 'how' just yet.
In the Stern-Gerlach experiment:Sure- but that's not memory, it's conservation of SAM. If you want to refer to conservation laws as "memory," go ahead, but no one's going to understand what you're talking about.
If the spin of a single electron is detected as 'up' on a Y axis test then if you repeat the same experiment on that same electron it always reads as the same on the Y axis.
(But randomly 50%/50% left/right or 50%/50% front/back on the X and Z axes if tested after any 'Y' test.)Again, yes, that's correct, that's uncertainty in SAM on two axes.
whether QM is that or not is another matterlast I checked the SM had 23 free parameters, consisting of the mixing angles in the CKM and PMNS matrices, the masses of various particles, and a few miscellaneous parameters. (It's worth noting that the Wikipedia article on the SM leaves out the PMNS angles and claims there are only 19 parameters.) The number may be decreased at some point, however this doesn't explain dimensionality in any obvious way, so that kind of gets left out.
@DS I don't disagree as to the QM mathematics predicting this "memory" effect. (How could I? I don't understand half of it.)It's actually proven to be not only part of the math, but part of the physical reality as proven by experiment. That's quite an important fact and one that you will wish to keep carefully in mind; this is the difference between theory and experiment.
But it most certainly is also a form of memory.Sure, but memory works because it relies on consistency. Consistency is a property of the dimensionality of spacetime; both conservation of momentum and conservation of energy emerge directly from consistency of results over space and over time, respectively, by Noether's Theorem. So we see that memory is dependent upon dimensionality, and the consistency of results across it. It's therefore better to talk about conservation laws than about memory, in this context, and much easier to understand.
The SG apparatus writes it and later reads it, and the orthogonal SG apparatus wipes it. Which means it has an actual underlying mechanism of some type. (Or the reproducible read after time has passed means our understanding of time is wrong??)You are correct, and there is a mechanism: it's Heisenberg uncertainty. This operates on spins on different axes, causing spin on one axis to become uncertain when spin on another axis is measured (and we can have a long discussion on what "measured" means if you like; you may find it interesting if you elect to do so, and it is on-topic).
You could make a reliable memory chip out of this though it would be huge and you would need to wipe before writing (like an old UV EPROM chip) and you must dump half of your freshly randomised electrons every time you write.Actually, there are some condensed matter physicists working on something called "spintronics" that are working on something very like this. Their prototype devices have cell sizes orders of magnitude smaller than any current memory technology, and they are robust across power-off, but they are not currently reliable enough for use in a general-purpose computing platform. You are, however, thinking along the right lines.
Blah, blah, blah......
In the universe we have only DYNAMICS. Motion of an object for example is dynamics which has its numerical order which is time. Entanglenemt is imediate and so has no numetical order.
@Hat, thanks, man. @EyeNStein, I also think this was a good discussion, and it might even go on a while. We're turning over some, rocks with interesting stuff under them.

(It allows for superluminal *quantum* information transmission, which is something entirely different. For a transporter you'd need to transfer *classical* information - and that isn't in the cards with QM)
