Reliable Teleportation of Ionic Motional States Through a Mapping Process

We show how to teleport reliably an arbitrary superposition of n=0 and n=1 vibrational number state between two distant ions. This is done by first mapping the vibrational state to be teleported into the internal degrees of freedom of a given ion. Then we handle with the internal superposition state following Bennett's original protocol and a recently proposed technique for teleportation of ionic internal states [quant-ph/9903029]. Finally, the teleportation of the vibrational state is achieved by reversing the mapping process in the receiver ion. We remark that as in the teleportation of cavity field and atomic states, the teleportation of vibrational states is 100% successful for an ideal process.
