Where is the bug in Zenaan's idea about array of photons and Observed + Not Observed = 1 bit?
I think that's the next bit that you didn't quote:
they only let two observers in different locations see the same system simultaneously, without any way of controlling what either sees.
You can establish that both observers saw an entangled wave function collapse, after the fact. But before the wave function collapses, neither one can know what they'll see, and so they also can't know what the other will see.
But, apparently, they can predict what the other will see with > 85% accuracy, whilst theory says they should only be able to do so with 75% accuracy.
No, there's no "prediction". They can discover later that both sides saw the expected spins. It's vaguely like you're flipping coins, and someone on Mars is also flipping coins. And later you share notes, and find that you both got more or less the same sequence of heads and tails. Not perfect, but substantially better than chance. But neither side can choose the order of heads and tails, so they can't create messages.
So, each side tests their respective entangled photon (85% certainty of what the other side saw), then does it all again (another 85%), giving: 85% + 85% = 169% probability that each will "guess" what the other side saw! That sounds pretty close to certainty to me...
It's entangled electrons in diamonds, not photons. And you can only test each pair of entangled electrons once. Because after that, they're no longer entangled.
PS: I'm sure someone can do the math better than I... but hopefully you get the idea - each side "simultaneously" 'observes' their 'half' of an entangled photon pair, say each second, and use these to reduce the uncertainty, thereby reaching "1 bit" of information transfer...
As I understand it, no information transfer is possible.
