# Quantum telecloning and multiparticle entanglement

@article{Murao1999QuantumTA, title={Quantum telecloning and multiparticle entanglement}, author={Mio Murao and Daniel Jonathan and Martin Bodo Plenio and Vlatko Vedral}, journal={Physical Review A}, year={1999}, volume={59}, pages={156-161} }

A quantum telecloning process combining quantum teleportation and optimal quantum cloning from one input to M outputs is presented. The scheme relies on the establishment of particular multiparticle entangled states, which function as multiuser quantum information channels. The entanglement structure of these states is analyzed and shown to be crucial for this type of information processing.
