TLDR
In this article, a quantum telecloning process combining quantum teleportation and optimal quantum cloning from one input to M outputs is presented, which relies on the establishment of particular multiparticle entangled states, which function as multiuser quantum information channels.Abstract:
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.read more

Graph states for quantum secret sharing
Damian Markham,Barry C. Sanders +1 more
TL;DR: This approach provides a generalization of threshold classical secret sharing via insecure quantum channels beyond the current requirement of 100% collaboration by players to just a simple majority in the case of five players.

Quantum secret sharing
TL;DR: This work shows how GHZ states can be used to split quantum information into two parts so that both parts are necessary to reconstruct the original qubit.
