Abstract
In this paper, we present a controlled quantum teleportation protocol. In the protocol, quantum information of an unknown state is faithfully transmitted from a sender (Alice) to a remote receiver (Bob) via the GHZ entangled ions under the control of the supervisor Charlie. The apparent Bell-state measurements that Alice should perform in order to teleport her ions are not needed.
