量子信息的块同步

Block synchronization for quantum information

Yuichiro Fujiwara

摘要:

定位连续量子信息块的边界是高级量子计算和量子通信系统的基本构建块。我们发展了一种编码理论方法,当块同步丢失时,不依赖于外部同步,正确地定位量子信息的边界。该方法还以类似于传统量子纠错码的方式保护量子比特免受退相干,无缝地实现同步恢复和纠错。通过这种方法给出了一族同时具有同步性和纠错性的量子码。

英文摘要:

Locating the boundaries of consecutive blocks of quantum information is a fundamental building block for advanced quantum computation and quantum communication systems. We develop a coding theoretic method for properly locating boundaries of quantum information without relying on external synchronization when block synchronization is lost. The method also protects qubits from decoherence in a manner similar to conventional quantum error-correcting codes, seamlessly achieving synchronization recovery and error correction. A family of quantum codes that are simultaneously synchronizable and error-correcting is given through this approach.
