Query: The Orientation of Local Spatial Reference Frames in Quantum
  Teleportation   Bennett et al.'s original article on quantum teleportation did not address
explicitly synchronizing the orientation of the local spatial reference frames
from and to which teleportaton occurs where the state teleported is spin 1/2
along the z axis. They wrote that only two bits of information need to be
conveyed classically where the state to be teleported concerns spin 1/2 along
the z axis. That only two bits of information need to be classically conveyed
could imply that such synchronization is not needed for it would require more
classically conveyed information. A gedankenexperiment is presented regarding
the orientation of the local spatial reference frames exploring whether such
synchronization is not needed even though it was apparently assumed by Bennett
et al. that it was required. It is often assumed that there is an absolute, as
opposed to a relative, orientation of objects in space. This assumption should
be open to empirical test, especially in view of evidence in psychology that
the orientation of objects in space is not absolute.
