摘要
借助经典级联码的思想,详细阐述了通过适当选择量子码作为外码和内码,构造一般意义量子级联码的过程.在此基础上,通过选择量子RS码作为外码,一组特殊结构的量子码作为内码,具体构造出了一类量子级联码,证明了其是量子好码.在量子纠错码领域中,这是首次利用经典坏码构造出量子好码.
Using the idea of code concatenation in classical coding theory, we make the suggestion oi constructing general concatenated quantum codes by choosing certain quantum codes as outer code and inner code. Then by concatenating quantum RS outer codes with a set of special quantum inner codes, one can construct a family of concatenated quantum codes, which is asymptotically good. In the field of quantum error-correcting codes, this is the first time that a family of asymptotically good quantum code is constructed using bad classical codes.
