Quantum Teleportation of an Arbitrary Two-Ion State by Using a Genuine Four-Ion Entangled State in Ion-Trap Systems

We propose a scheme to realize the deterministic quantum teleportation of an arbitrary two-ion state by using a genuine four-ion entangled state in ion-trap systems. The scheme does not involve Bell-state measurements and only needs to make the single-ion measurements. Our scheme is insensitive to both the initial vibrational state and heating, which is of importance in view of experiment.
