Rate-optimal Coded Quantum Networks, Eavesdropping and more:
We encode k qubits of quantum information over an n-node network, in a distributed fashion with one qubit per node. A procedure is devised to recover the encoded information from a quantum coded network using modified graph state codes that saturate the quantum Singleton bound and resilient to single node failure. Insights into rate-optimal coded quantum network designs  are provided.
Also, the advantage of quantum coding over graph states resilient to single node failure is explored in . Further, graph state codes are explored within the context of node recovery from an eavesdropping attack .
