Teleportation of a Three-Particle Entangled GHZ State via a Two-Particle Entangled Quantum Channel

摘要

A scheme of teleportation of a three-particle entangled GHZ state through a two-paticle entangled quantum channels is proposed, the two-particle nonmaximally entangled state is taken as quantum channels, We find that by implementing H transformation and von Neumann measurement,introducing an ancilly qubit, constructing an unitary transformation properly, teleportation of three-paticle entangled GHZ state can be implemented with certain probability. This scheme saves the quantum entanglement channel resources comparing with other shemes.
