[QUOTE="Janx, post: 5893404, member: 8835"] my eyes may have glazed over a bit, but thanks for taking the time to supply an example. I suspect the "hidden variable" is something data communications/computer science people who develop low-level protocols for passing data solve with agreed upon patterns that can be identified. For instance, Morse code is really a binary protocol (dots and dashes). We define a dot to be an asserted signal with a duration between X1 and X2. We define a Dash to have a duration between X2+Z and X2+Z+D where the values of Z and D and ensure that a Dash's duration does not overlap with a dot's duration. At that point, the reciever simply listens for the signal to assert itself, measures the duration, and determines if it was a dot or a dash. Note, this example doesn't account for static on the line where a dashed assertion on the line is interrupted by noise, appearing to be a deassertion, and thus could be mistaken for dots or dashes, instead of a singal dash. But the protocol worked for the telegraph, because the assertion signal was strong enough that any variance was still within the range of "off" or "on" Once a protocol like this is established, the device is built (photons, magic rocks, beats me) and the 2 nodes are deployed. At Node A, I assert a signal (up-down polarized photons I guess), and on Node B, you listen for diagonal photons (once again, I guess from your explanation). You keep track of all the . and - you see and in what order, and parse that into the message. For bi-directional communication, it is more than likely that these Quantum Repeaters have pairs of pairs. Node A has a a quantum-half wired up to detect a signal, and it has a different quantum-half wired up to be tickled. Node B has the corresponding halves. In my original example of the boxes with an RJ45 connector, that's an 8 wire connector, with so many wires for recieving, so many for sending, and a ground. In the Quantum Repeater, the "ground" wire could instead be used as a timing pulse so that the reciever can synchronize what it's recieving on the other lines. I don't know how quantum physicists think about this stuff, but once you say you have a QM box that can induce X number of states or values from the input node to the output node, the Electrical Engineers and Computer Science guys have expertise to turn that into a communication protocol. Now if you instead were referring to a wierd behavior where dots and dashes start coming out before I send them as [MENTION=6674889]Gorgoroth[/MENTION] might have been talking about, that sounds cool, but I'd have to know more before I could discern if that's a problem or not. And of course, I have no idea if QM technology exists where you can tickle Object A and detect the tickling in Object B. By "tickle" I mean do whatever you got to do to get that effect. Shine a light on it, lick it, send an electrical current into it, whatever. [/QUOTE]
