Quantum-information distribution via entanglement
Physical Review A - Atomic, Molecular, and Optical Physics 61:3 (2000) 323111-3231111
Abstract:
We present a generalization of quantum teleportation that distributes quantum information from a sender's d-level particle to N0 particles held by remote receivers via an initially shared multiparticle entangled state. This entangled state functions as a multiparty quantum information distribution channel between the sender and the receivers. The structure of the distribution channel determines how quantum information is processed. Our generalized teleportation scheme allows multiple receivers at arbitrary locations, and can be used for applications such as optimal quantum information broadcasting, asymmetric telecloning, and quantum error correction.Two-state teleportation

Abstract:
Lower bounds for two-state teleportation fidelity were computed using a nonmaximally entangled pure state as a channel, and the exact result for the two-state fidelity with no entanglement. Only pure entangled states were considered as channels for teleportation. The results provide additional information on the respective roles of classical information and quantum entanglement in the new field of quantum information processing.Manipulation of entangled states for quantum information processing
