  This paper provides a scheme for generating maximally entangled qubit states
in the anti-Jaynes-Cummings interaction mechanism, so called entangled
anti-polariton qubit states. We demonstrate that in an initial vacuum-field,
Rabi oscillations in a cavity mode in the anti-Jaynes-Cummings interaction
process, occur in the reverse sense relative to the Jaynes-Cummings interaction
process and that time evolution of entanglement in the anti-Jaynes-Cummings
interaction process takes the same form as in the Jaynes-Cummings interaction
process. With the generated anti-polariton qubit state as one of the initial
qubits, we present quantum teleportation of an atomic quantum state by applying
entanglement swapping protocol achieving an impressive maximal teleportation
fidelity~$F_\rho=1$.
