Complete Security Solution for Practical Quantum Network Coding

Quantum network coding (QNC) is expected to enable multiple quantum data packets to be fused before the transmission via the bottleneck channel in order to improve the transmission efficiency and the total throughput of quantum networks. Although several QNC schemes have been constructed, they are unable to meet the practical application requirements due to the fact that they lack a complete security solution. To tackle this issue, a practical secure QNC scheme is constructed. Compared with existing methods, the proposed QNC scheme is more practical and most importantly it can provide complete security against both information leakage and pollution attacks, which greatly contributes to global quantum communication networks.
