Remarkable Degenerate Quantum Stabilizer Codes Derived from Duadic Codes
Salah A. Aly, Andreas Klappenecker, Pradeep Kiran Sarvepalli
Good quantum codes, such as quantum MDS codes, are typically nondegenerate, meaning that errors of small weight require active error-correction, which is -unfortunately- itself prone to errors. In this paper, examples of degenerate quantum codes are constructed that alleviate this problem in that they allow some errors of small weight that do not require active error correction. In particular, two new families of [[n, 1, ges radicn]]qdegenerate quantum codes are derived from classical duadic codes
