Faithful Telecloning with Multiparticle Entanglement

We study the 1 → N faithful telecloning of two linear-independent states of a one-qubit system. Based on the analysis of the probabilistic cloning machine, we construct a multiparticle entangled state, and present a telecloning scheme under local operations and classical communication (LOCC). The success probability is greater than half of the optimal probability of the probabilistic cloning machine. Specifically, we show how to prepare the three-particle entangled state needed by 1 → 2 telecloning under LOCC using the Greenberger-Horne-Zeilinger state as resource. All the operations in 1 → 2 telecloning are within the reach of current technology.
