Abstract: | An alternative scheme is presented for teleportation of a two-atom
entangled state in cavity quantum electrodynamics (QED). It is based
on the resonant atom--cavity field interaction. In the scheme, only
one cavity is involved, and the number of the atoms needed to be
detected is decreased compared with the previous scheme. Since the
resonant atom--cavity field interaction greatly reduces the
interaction time, the decoherence effect can be effectively
suppressed during the teleportation process. The experimental
feasibility of the scheme is discussed. The scheme can easily be
generalized to the teleportation of N-atom
Greeninger--Horne--Zeilinger (GHZ) entangled states. The number of
atoms needed to be detected does not increase as the number of the
atoms in the GHZ state increases. |
