Abstract

We propose a scheme for cloning an unknown single qutrit state with assistance. The scheme includes a qutrit-state teleportation at the cloner's site. During this process different states (i.e., the maximally entangled or non-maximally entangled two-qutrit states) as quantum channel are taken into account. After the teleportation, to help the cloner Alice to reestablish the unknown state, the state preparer Victor should perform a single-qutrit measurement and tell her the outcome. In this scheme, the success probability of cloning the original state is determined by the used quantum channel.
