Constructions of new families of nonbinary asymmetric quantum BCH codes and subsystem BCH codes
نویسندگان
چکیده
Two code constructions generating new families of good nonbinary asymmetric quantum BCH codes and good nonbinary subsystem BCH codes are presented in this paper. The first one is derived from q-ary Steane’s enlargement of CSS codes applied to nonnarrow-sense BCH codes. The second one is derived from the method of defining sets of classical cyclic codes. The asymmetric quantum BCH codes and subsystem BCH codes here have better parameters than the ones available in the literature.

On Quantum and Classical Error Control Codes: Constructions and Applications
It is conjectured that quantum computers are able to solve certain problems more quickly than any deterministic or probabilistic computer. For instance, Shor’s algorithm is able to factor large integers in polynomial time on a quantum computer. A quantum computer exploits the rules of quantum mechanics to speed up computations. However, it is a formidable task to build a quantum computer, since...
متن کاملAsymmetric and Symmetric Subsystem BCH Codes and Beyond
Recently, the theory of quantum error control codes has been extended to subsystem codes over symmetric and asymmetric quantum channels – qubit-flip and phase-shift errors may have equal or different probabilities. Previous work in constructing quantum error control codes has focused on code constructions for symmetric quantum channels. In this paper, we develop a theory and establish the conne...

متن کاملOn the Construction of Optimal Asymmetric Quantum Codes
Quantum error-correcting codes have gained prominence since the initial discovery of Shor and Steane. In 1998, Calderbank et al. presented systematic methods to construct binary quantum codes, called stabilizer codes or additive codes, from classical error-correcting codes. Since then the field has made rapid progress, many good binary quantum codes were constructed by using classical error-cor...
متن کاملConstructing Asymmetric Quantum and Subsystem Cyclic Codes
It is recently conjectured in quantum information processing that phase-shift errors occur with high probability than qubit-flip errors, hence the former is more disturbing to quantum information than the later one. This leads us to construct asymmetric quantum error controlling codes to protect quantum information over asymmetric channels, PrZ ≥ PrX. In this paper we present two generic method...
