WHICH KIND OF TWO-PARTICLE STATES CAN BE TELEPORTED THROUGH A THREE-PARTICLE QUANTUM CHANNEL?

The use of a three-particle quantum channel to teleport entangled states through a slight modification of Bennett's procedure is studied. It is shown that it is not possible to perform successful teleportation of an arbitrary and unknown two-particle entangled state, following our version of Bennett's procedure. On the contrary, it is shown which, and in how many different ways, particular classes of two-particle states can be teleported.
