| Abstract: | Based on the standard teleportation scheme and the controlled teleportation scheme for an unknown quantum state of a single two-level particle,it was generalized the discussion to two-particle cases and performed a detailed calculation for the two particle problem.It was discussed briefly the problem of transportation of any unknown quantum state of arbitrary number of two-level particles also. |

| Keywords: | quantum teleportation quantum entanglement swapping EPR effect Bell states measurement two-particle entangled state three-particle GHZ state. |
