چکیده
Teleportation of an EPR pair using triplet in state of the Horne-Greenberger-Zeilinger form to two receivers is considered. It needs a three-particle basis for joint measurement. By contrast the one qubit teleportation the required basis is not maximally entangled. It consists of the states corresponding to the maximally entanglement of two particles only. Using outcomes of measurement both receivers can recover an unknown EPR state however one of them can not do it separately. Teleportation of the N-particle entanglement is discussed.

Teleportation of a two particle pure entangled state by triplet GHZ is considered for continuous variables. The three-particle basis needed for joint measurement is found. It describes a measurement of momentum one of the particle with total moment and relative position of the two others. Optical realization using squeezed state of the light is discussed.
