Abstract
A quantum telecloning process combining quantum teleportation and optimal q uantum cloning from one input to M outputs is presented. The scheme relies on the establishment of particular multiparticle entangled states, which fu nction as multiuser quantum information channels. The entanglement structur e of these states is analyzed and shown to be crucial for this type of info rmation processing. [S1050-2947(99)07301-1].
