It is shown that quantum teleportation and entanglement swapping can be eas
ily derived from Einstein-Podolsky-Rosen correlations and special relativit
y. This raises the question of what is really teleported in a teleportation
experiment. It is also shown that the behavior of two photons that arrive
together at a beam splitter can be seen as a particular case of a nonlocal
effect in which they arrive "together" at two different beam splitters.
