QUITS is a modular and flexible circuit-level simulator for quantum low-density parity-check (QLDPC) codes. It is designed so users can choose and mix different options for each module independently: ...

Abstract: Quantum burst error correction codes (QBECCs) are of great importance to deal with the memory effect in quantum channels. As the most important family of ...

Abstract: As cyclic codes and maximum distance separable (MDS) codes, cyclic MDS codes have very nice structures and properties, which have been intensively investigated in literature due to their ...

Abstract: In this paper, we introduce a class of dualcontaining 2 -generator quasi-cyclic codes over $G F(4)$. By Hermitian construction, we show computation ...

COLUMBIA, S.C. – Cyclic Materials, a leader in recycling solutions for rare earth elements, today announced it selects Chesterfield County to establish the company’s first East Coast operation. The ...

Abstract: We investigate quasi-cyclic low-density parity-check (QC-LDPC) codes for nonergodic block-fading channels. A construction method for designing QC-LDPC codes is presented. With careful design ...

Nous Research, the open-source artificial intelligence startup backed by crypto venture firm Paradigm, released a new competitive programming model on Monday that it says matches or exceeds several ...

Abstract: We compute the weight distribution of binary cyclic codes with arbitrarily many generalized Niho-type nonzeroes, where the exponents of the nonzeroes nearly form a long arithmetic ...

Abstract: The capability of QC-SC-LDPC codes to be employed in broadcasting systems has been studied in previous research. However, the implementation-oriented features such as rate-compatibility and ...

Abstract: The b-symbol metric is a generalization of the Hamming metric. Linear codes in the b-symbol metric have been used in the read channel whose outputs consist of b consecutive symbols. The ...
