Abstract: | Bell inequality tests performed by atomic cascade experiments always make use of a coincidence counting electronics. It is shown that such electronics can act as a “source of nonlocality” in the correlation function, even if every phenomenon involved is perfectly local. A simple example illustrating this situation is given. |
