Does it imply instantaneous, or faster than light transference of information? AG I defined non-local above: whatever happens at A does not affect B and *vice versa*. It has nothing to do with faster-than-light transfer of information. If there was some FTL transfer between A and B, then the effect would be local. The idea that non-locality means FTL effects is a common confusion. That idea is totally wrong. Bruce It might be, as you write, a common confusion, but how else can a measurement at A not effect a measurement at B , and vice versa, and yet be correlated, without faster-than-light transference of information. It does seem to me that non-local implies denial of realism. AG You just have to stop thinking about it in classical terms. Bruce If my interpretation is wrong, this is too classical, what's the correct interpretation? AG Instead of thinking in terms of a local Hamiltonian, depending on just one spacetime point; you have to think of a non-local Hamiltonian, depending on more than one spacetime point. Bruce Unfortunately, what you propose is above my head. Firstly, I forget how to apply a classical Hamiltonian to this problem of two separated events, and what a non-local Hamiltonian would look like and how it would be applied. I don't wish to burden you with the technical explanation, so maybe someone on this thread is up to the task.
