Entanglement-assisted quantum error-correcting codes from subfield subcodes of projective Reed-Solomon codes (2304.08121v2)
Published 17 Apr 2023 in cs.IT, math.AC, and math.IT
Abstract: We study the subfield subcodes of projective Reed-Solomon codes and their duals: we provide bases for these codes and estimate their parameters. With this knowledge, we can construct symmetric and asymmetric entanglement-assisted quantum error-correcting codes, which in many cases have new or better parameters than the ones available in the literature.
