Abstract:
A new quantum channel composed of two multi-particle partially entangled states for quantum teleportation (QT) is constructed. Two explicit controlled probabilistic teleportation tripartite schemes are proposed for arbitrary three-particle partially entangled GHZ state and W state. The arbitrary GHZ state and W state can be teleported with a certain probability to the receiver who introduces an auxiliary particle and performs the corresponding unitary operation, with the help of the measurement of Bell-state and single-particle from the sender and the controller. The overall success probabilities of two QT schemes are both
8d^2n^2
(
d
and
n
are the coefficients of the quantum channel).
