The photon's wave function affects only one out of the atoms, regardless of its position within the row, thereby manifesting not only non-local but also non-sequential characteristics. It also turns out that, out of n atoms, each one has a probability which is higher than the normal 1/n to be the single affected one.4 pages, 2 figs, RevTeX 4b5Quantum Physicstext
