I am not educated in QM, so this post is to ask a few questions related the the non-locality/entanglement controversy for which I am hoping for a simple answer.
As I understand an example of the entanglement part, what appears to two observers is two partcles having a combined propery that their spin directions are opposite. If there are two devices far apart, each positionsed to test spin with respect to the same axis direction. When each of these two particles arrive at its target device, its spin will be determined, and when both spins are determined it will be found that they have opposite spins.
Assume that there is a clock associated with each device, and the clock times are synchronized, so that the determination of each measured spin is associated with a specific time.
Assume the two devices are separated by a distance D, and that the two times related to the devices determining a spin value differ by a time T. Therefore this result might be interpreted as the the ealier spin determination influences the later spin determination and the influence traveled at a speed of D/T, and the configuration might well be that D/T > c.
I think I understand that the transmission of influence does not in any way permit an observer to predict the spin of the second particle before the particle arrives at its devise.
My question is the following. Does the influence from the location of one device determining a spin value and the second devise determining a spin value constitute a transmission of information? That is, is influence information? Also ,is this a controversial question?
If one defines the transmission of influence to NOT be a transmission of information, then no information has traveled faster than c. Would this mean that there is not any non-locality issue? If not, why not?
