So if I put a Fermion here in the Good Ol' USA in one quantum state, instantly some other particle in Iraq has to assume a different quantum state.

That is the basis of my question, although the DNA testing was a good option. :-)How would I know to and why would I look in Iraq for the particle/wave with the changed state? Basically, how do you define the limits of your search or how do you predetermine which Fermion to examine??

I have no idea. I'm an EE, although I took undergraduate physics I-IV. I had friends who were graduate physics students and sort of pissed them off by declaring that Pauli's exclusion principal (two fermions cannot simultaneously occupy the same quantum state - although I thought part of separation was spatial) was one of the most fundamental laws of physics. It is actually, in that there is no other explaination for it. The Bernoull effect, for instance, can be explained as a consesqence of other physical laws. The exclusion principal is entirely responsible for the form of ordinary matter as we know it. The reason you can't just compress a steel bar is because the electrons in the same quantum state can't be within a certain distance of each other. The electron solves its problem by jumping into a higher quantum state, one requiring more energy. This energy per unit distance of compression manifests itself as force required to compress the bar. (Electrostatic attraction of the electrons for the nucleus of neighboring atoms explains resistance to stretching.)
