Controlled teleportation of an unknown 3D two-particle state via 3D partially entangled states
A scheme is presented to realize the controlled teleportation of an unknown three dimensional (3D) two-particle state by using a non-maximally entangled two-particle state and a non-maximally entangled three-particle state in the 3D space as the quantum channels, and one of the particles in the channels is used as the controlled particle. Analysis shows that when the quantum channels are of maximal entanglement, namely the channels are composed of a 3D Bell state and a 3D GHZ state, the total success probability of the controlled teleportation can reach 1. And this scheme can be expanded to control the teleportation of an unknown D-dimensional two-particle state.
