| Abstract: | We present a scheme for bidirectional controlled teleportation by using a five-qubit composite GHZ-Bell state as quantum channel. Based on the C-not operation and single qubit measurements, Alice may transmit an arbitrary single qubit state of qubit A to Bob and Bob may transmit an arbitrary single qubit state of qubit B to Alice via the control of the supervisor Charlie. |
