  We present a physical (gedanken) implementation of a generalized remote state
preparation of relativistic quantum field states for an arbitrary set of
observers. The prepared states are created in regions that are outside the
future light-cone of the generating region. The mechanism, which is based on
utilizing the vacuum state of a relativistic quantum field as a resource, sheds
light on the well known Reeh-Schlieder theorem, indicating its strong
connection with the mathematical phenomenon of superoscillations.
