# Asymmetric quantum multicast network coding: asymmetric optimal cloning over quantum networks

@article{Hirota2019AsymmetricQM, title={Asymmetric quantum multicast network coding: asymmetric optimal cloning over quantum networks}, author={Yuichi Hirota and Masaki Owari}, journal={arXiv: Quantum Physics}, year={2019} }

In this study, we consider a quantum version of multicast network coding as a multicast protocol for sending universal quantum clones (UQCs) from a source node to the target nodes on a quantum network. By extending Owari et al.'s previous results for symmetric UQCs, we derive a protocol for multicasting $1\rightarrow 2$ ($1\rightarrow 3$) {\it asymmetric} UQCs of a $q^r$-dimensional state to two (three) target nodes.Our protocol works under the condition that each edge on a quantum network…

This paper overcome the limitation to linear protocols and describes a new communication protocol for perfect quantum network coding that improves over the previous one as follows: (i) the new protocol does not put any condition on the underlying classical coding scheme, that is, it can simulate nonlinear communication protocols as well, and (ii) the amount of classical communication sent in the protocol is significantly reduced.
