| Abstract: | We demonstrate that an eight-atom composite W-Bell state can be used to realize the deterministic quantum state sharing of an arbitrary two-atom state in cavity QED. In the scheme, it does not involve Bell-state measurement and only needs to perform the single-atom measurements. Our scheme is not sensitive to both the cavity decay and the atom radiation, which is of importance in view of decoherence. |
