Quantum turbo codes (QTC) have shown excellent error correction capabilities in the setting of quantum communication, achieving a performance less than 1 dB away from their corresponding hashing bounds. Existing QTCs have been constructed using uniform random interleavers. However, interleaver design plays an important role in the optimization of classical turbo codes. Consequently, inspired by the widely used classical-to-quantum isomorphism, this paper studies the integration of classical interleaving design methods into the paradigm of quantum turbo coding. Simulations results demonstrate that error floors in QTCs can be lowered significantly, while decreasing memory consumption, by proper interleaving design without increasing the overall decoding complexity of the system.
量子Turbo码（QTC）在量子通信环境中已展现出卓越的纠错能力，其性能与相应的哈希界相差不到1dB。现有的QTC是使用均匀随机交织器构建的。然而，交织器设计在经典Turbo码的优化中起着重要作用。因此，受广泛使用的经典到量子同构的启发，本文研究了将经典交织设计方法集成到量子Turbo编码范式中。仿真结果表明，通过适当的交织设计，在不增加系统整体解码复杂度的情况下，可显著降低QTC中的误码平底，同时减少内存消耗。
