Opportunistic Quantum Network Coding
Tao Shang, Gang Du, Jianwei Liu
It seems impossible to endow opportunistic characteristic to quantum network on the basis that quantum channel cannot be overheard without disturbance. We propose an opportunistic quantum network coding scheme by taking full advantage of channel characteristic of quantum teleportation. On one hand, it utilizes quantum channel for the secure transmission of quantum states and can detect eavesdroppers by means of quantum channel verification. On the other hand, it utilizes classical channel for opportunistic listening and can acquire coding opportunity from neighbors. Analysis results show that our scheme can reduce the times of transmissions for relay nodes and can effectively defend against classical passive attack and quantum active attack.
