Abstract

We address continuous variable 1 →2 telecloning based on three-mode entangled states of the radiation field. After reviewing existing protocols using phase-space formalism we suggest a novel scheme which allows telecloning with optimal fidelity also in the high energy regime. Being not limited by energy constraints our scheme is suitable to be implemented with feasible three-mode entanglement sources.
