Controlled Teleportation of the Two-Ion Entangled State.

A simple scheme for controlled teleportation of an arbitrary two-ion entangled state using a bell and GHZ entangled state as quantum channel is proposed in trapped ion systems. An arbitrary two-ion entangled state can be teleported perfectly with the help of the cooperation. In our scheme the ions are simultaneously excited by a laser. Our scheme is insensitive to both the initial vibrational state and heating. The probability of the success in our scheme is 1.0. [ABSTRACT FROM AUTHOR]
