摘　　要：The probability of successful controlled teleportation of an unknown qubit using a general three-particle state is investigated. The analytic expressions of maximal probabilities via several kinds of tripartite states are given, including a tripartite Greenberger-Horne-Zeilinger state and a tripartite W-state.The probability of successful controlled teleportation of an unknown qubit using a general three-particle state is investigated.
