We present a rare example of a decay mechanism playing a constructive role
in quantum information processing. We show how the state of an atom trapped
in a cavity can be teleported to a second atom trapped in a distant cavity
by the joint detection of photon leakage from the cavities. The scheme, wh
ich is probabilistic,.requires only a single three level atom in a cavity.
We also show how this scheme can be modified to a teleportation with insura
nce.
