Physicists at the Commerce Department's National Institute of
Standards and Technology (NIST) have demonstrated "teleportation" by
transferring key properties of one atom to another atom without using
any physical link, according to results reported in the June 17, 2004,
issue of the journal Nature.
Unlike the "beaming" of actual physical objects and people between
distant locations popularized in the Star Trek science fiction series,
the term "teleportation" is how physicists describe a transfer of
"quantum states" between separate atoms. The quantum state of an atom
is a description of such things as its energy, motion, magnetic field
and other physical properties...

That (the word "another") is a misnomer. All atoms of the same type
are identical -- literally. They have no more individual identity as
separate objects than waves on an ocean do. If you're transporting
the state, you're transporting the atom. The correct title is
"Teleportation of Atoms...", not merely "Teleportation of Atomic
States..."
