Abstract

In this paper, we give an experimentally feasible scheme for the remote state preparation by the prior share of an entangled state in cavity QED. The whole process of the remote state preparation for a single-atom state and a two-atom entangled state is shown. We find that only one classical bit and one single-atom state measurement is needed for the remote state preparation of a multi-atom entangled state.
