| 摘 要： | A scheme is presented for teleporting an unknown state in a trapped ion system. The scheme only requires a single laser beam. It allows the trap to be in any state with a few phonons, e.g. a thermal motion. Furthermore, it works in the regime, where the Rabi frequency of the laser is on the order of the trap frequency. Thus, the teleportation speed is greatly increased, which is important for decreasing the decoherence effect. This idea can also be used to teleport an unknown ionic entangled state.

| Abstract: | A scheme is presented for teleporting an unknown state in a trapped
ion system. The scheme only requires a single laser beam. It allows
the trap to be in any state with a few phonons, e.g. a thermal
motion. Furthermore, it works in the regime, where the Rabi
frequency of the laser is on the order of the trap frequency. Thus,
the teleportation speed is greatly increased, which is important for
decreasing the decoherence effect. This idea can also be used to
teleport an unknown ionic entangled state. |
