由Duadic码导出的显著退化量子稳定子码
Remarkable Degenerate Quantum Stabilizer Codes Derived from Duadic Codes
摘要：
好的量子码，如量子MDS码，通常是非退化的，这意味着小重量的错误需要主动纠错，这是-矛盾的-本身容易出错。另一方面，去相干自由子空间不需要主动纠错，但在最小距离方面表现不佳。在本文中，简并量子码的例子构造有更好的最小距离比消相干自由子空间，并允许一些小的重量，不需要主动纠错的错误。特别地，从经典的duadic码中导出了两类新的[[n，1，>= sqrt（n）]] q退化量子码.
英文摘要：
Good quantum codes, such as quantum MDS codes, are typically nondegenerate, meaning that errors of small weight require active error-correction, which is--paradoxically--itself prone to errors. Decoherence free subspaces, on the other hand, do not require active error correction, but perform poorly in terms of minimum distance. In this paper, examples of degenerate quantum codes are constructed that have better minimum distance than decoherence free subspaces and allow some errors of small weight that do not require active error correction. In particular, two new families of [[n,1,>= sqrt(n)]]_q degenerate quantum codes are derived from classical duadic codes.
