| Abstract: | A scheme for controlled teleportation of an unknown single-particle state with a three-particle entangled W state and positive operator valued measure(POVM) is proposed;By introducing an auxiliary particle and performing an unitary transformation,controlled teleportation will be succeeded with certain probability. |

| Keywords: | POVM unitary transformation single-particle state |
