Teleportation of a two-particle entangled state via entanglement swapping. (English) Zbl 1274.81016
Summary: A scheme of teleporting a two-particle entangled state is proposed. In this scheme, two pairs of entangled particles are used as quantum channel. It is shown that if the two pairs of particles are not-maximally entangled, the probability of successful teleportation is determined only by the smallest superposition coefficient.
