Abstract: | In this paper, we propose a scheme for transferring an unknown atomic entangled
state via cavity quantum electrodynamics (QED). This scheme, which has a successful
probability of 100 percent, does not require Bell-state measurement and performing
any operations to reconstruct an initial state. Meanwhile, the scheme only involves
atom--field interaction with a large detuning and does not require the transfer of
quantum information between the atoms and cavity. Thus the scheme is insensitive to
the cavity field states and cavity decay. This scheme can also be extended to
transfer ring an entangled state of $n$-atom. |
