摘要：

We present a scheme for probabilistic teleportation via a non-maximally entangled GHZ state. Quantum teleportation will succeed with a calculable probability. The teleportation process requires the sender to make a generalized Bell state measurement, the cooperator to perform a generalized X basis measurement, and the receiver to perform a collective unitary transformation and to make a measurement on an auxiliary particle. The success probability of the teleportation is given. We also obtain the maximum of the success probability of the teleportation.
