Human Eye Could Detect Spooky Action At a Distance

KentuckyFC writes "The human eye is a good photon detector--it's sensitive enough to spot photons in handfuls. So what if you swapped a standard photon detector with a human eye in the ongoing experiments to measure spooky-action-at-a-distance? (That's the ability of entangled photons to influence each other, no matter how far apart they might be.) A team of physicists in Switzerland have worked out the details and say that in principle there is no reason why human eyes couldn't do this kind of experiment. That would be cool because it would ensure that the two human observers involved in the test would become entangled, albeit for a short period time. The team, led by Nic Gisin, a world leader on entanglement, says it is actively pursuing this goal (abstract) so we could have the first humans to experience entanglement within months."

      Take for example, the visual cortex. It presents itself to our consciousness as a unified phenomenon, wherein we experience millions of neural firings simultaneously as our field of vision, and yet these neuronal experiences are spatially distributed. Sure, there's a cognitive level where it all "comes together" through information processing, but the thing is we nevertheless seem to experience the raw distributed visual data at some level pre-cognitively.

      Of course, it makes sense that as holistic experiencing entities we exhibit this property. The alternative would be to have the data represented in consciousness serially, in the manner of language, which would of course be ridiculous at the earliest stages of cognition.

      The overall experience of seeing is tied together simply by the simultaneity of its constituent elements in the present moment - presumably in the phase change from the immediately-past moment, since change is the seed of awareness. But what keeps this experience from being utterly chaotic and meaningless is the "context" of these simultaneous physical events, and their presence in an information-processing system - the brain.

      Does this constitute entanglement? Certainly, there must be some essence of entanglement involved. I'm fuzzy on the specifics, but awhile ago I recall reading that the brain has a structure at its center which generates radial magnetic pulses from front-to-back at something like 50Hz. The generated field has the effect of aligning atoms in the brain. Is spatial alignment in some way related to entanglement?

    - Why entanglement is difficult to achieve and not even fully understood how to reproduce consistently.

    - Why there's an inverse relationship between accuracy of measurement of speed and location - the more you interact with the wavefront, the more uncertain it becomes. Also why pinpointing the exact location of a particle makes it seem like its speed is impossible to measure (it seems to be able to move in any direction at any speed, because we're unable to predict how the causality of interaction of the parts of the hologram works). If you pinpoint its exact speed, then knowing its location is really knowing the point it moved away from an instant ago and the point it will move to, and that would also take predicting the interaction of the hologram wavefronts, which we can't do and so seems random.

    - The whole 'spooky action at a distance' - because there actually is no distance. Once the waves interact in such a way that disturbing one causes it to take on form X, and the in-phase wave to take on the opposite form, they are really "at the same location" until they are disturbed.

      This article doesn't seem to be making that claim at all. It states that people who have similar neurological damage suffer from similar impediments in language processing. That's like saying that computers with damaged GPUs are going to suffer from the same rendering problems; it makes no statement whatsoever about the overall structural compatibility between two computers.

      From the article:

      Our findings not only show hemispheric differences in connections between inferior frontal and posterior temporal regions but also critically suggest that individuals with more symmetric patterns of connection are better overall at learning words using semantic association.

      So what is being discussed here is the biological process by which language processing occurs. At no point does it show that there is any neurological identicality between one person's concept of "apple" and another's.

      I thought this was a discussion based in hard science, not pseudo-occult chicanery. Sorry, but this just strikes too close to that old mystical sawhorse of "vibrations".

      Did you read my P.S.? It was a lot more interesting article about a bacteria that used quantum entanglement to process energy from the sun.

      In any case, you seem to think that I'm trying to sell you something. I'm actually just describing a way of visualizing what I'm doing with artificial intelligences. It could be that what I'm modeling doesn't exist in the real world, but, as it turns out, that's okay if it can solve a practical problem, like finding depth in a photograph.

      What I was trying to impress on you is that we have pathways that lead to various areas of processing in the brain. For example, our visual pathways have a lot of branches, but they start with the eyes, and branch out in various ways, but with a pattern.

      If those individual neurons can "sense" quantum entanglement, and if quantum entanglement is more likely with proximity, then it could be that pattern recognition pathways learn to make sense of the quantum entanglement.

      Earlier you asked me to prove that certain words like "red" and "table" followed certain neural patterns. I cannot prove anything like that. What has been proven is that we have pattern recognition neurons, and we have sight transfer pathways, and sound transfer neural pathways and we have all these specialized neurons for different tasks. Retinal neurons are very different from hippocampus (memory) neurons.

      Furthermore, these neurons are connected in similar ways for similar tasks. We have sight neurons that lead directly to our motor neurons, so we can react quickly, and we have memory neurons that constantly bounce signals back and forth, reinforcing what we've learned.

      All of our neurons can recognize patterns, so if you pre-suppose that there are quantum influences on the neurons, and that these quantum influences have patterns that are recognizable, it stands to reason that a pattern recognition device can make a sort of sense out of it.

      All of this abstract theory has a relation to actual nuts and bolts AI research. I'm working on it now, so I can't say if it is useful all. I have a hunch that it is, and that it's related to the problem of ESP. I have lots of experiments to do.

      What I'm saying is, don't feel like I'm some kind of new-wave preacher. I have no real interest in whether you believe me or not. My end goal is to make money, and whether you believe me is inconsequential as to whether I can play Go better than Gnu Go.

      You realize that avalanche photon detectors (APDs, which are more usually used in single-photon experiments) can't distinguish polarization either? If detecting polarization is important, you put a polarizing beam-splitter (PBS) in each arm (maybe some waveplates as well if you want a different basis from horizontal and vertical polarizations), and put an APD on each of its output ports. Given that most people have two eyes, there's no reason that a similar configuration of polarization optics can't be used.

      The reason that we normally use APDs rather than human eyes as single-photon detectors is because they have lower noise, greater detection efficiency, and can work at higher repetition rates. Plus, I'd rather fry an APD if I accidentally sent too much light into it while it was switched on, than blind myself.
