This is the last I'm going to respond to this.
The photons are 'entangled' which means their states are linked and co-dependant.
The states are no more "co-dependent" than two copies of the same book at different locations on the planet are. The primary difference in the quantum mechanical case is that because of superposition, each might be a mixed state of several books, and only the act of measurement would disclose which one, and that a decision to examine one of several non-commuting observables might be made after the books had been produced and were in transit. This would *NOT* imply in any way that examination of one book had any physical effect on the other, although correlation of measurements made on both books might demonstrate non-local collapse of the QM wavefunction, which is not, and never has been, a physical quantity. I can think of even a more extreme case. Suppose I have the same Barium atom in two laser traps tuned to different excited states and separated by a distance of 1,000 miles. I now have a 50/50 superposition of one state here, and a different state 1000 miles away. Even with the *SAME* particle in two different places, nothing I do to it in one place is detectable by a scientist in its other location, and the only correlations which demonstrate non-local effects require data from measurements from both of them. -- Eric Michael Cordian 0+ O:.T:.O:.
