報告題目:Two types of applications of the cyclotomy theory in the design of error-correction codes

報告摘要:Cyclotomy theory and generalized cyclotomy theory play an important role in the design of classical error-correction codes and quantum error-correcting codes. As a classical error-correction code, a double circulant self-dual code employs one generator matrix consists of two circulant matrices and possesses many good algebraic properties. By constructing double circulant generator matrixes using cyclotomy and generalized cyclotomy, we presented some double circulant self-dual codes with optimal minimum distances. As a new class of quantum error-correcting codes, quantum synchronizable codes can be used to correct the effects of both quantum noise on qubits and misalignment in block synchronization. We construct some new quantum synchronizable codes by cyclotomy and generalized cyclotomy. Synchronization capability of these codes can reach the upper bound, and some of them possess good error-correcting capability towards bit errors and phase errors.
