Abelian multi-cycle codes for single-shot error correction
Hsiang-Ku Lin, Pak Kau Lim, Alexey A. Kovalev +1
We construct a family of quantum low-density parity-check codes locally equivalent to higher-dimensional quantum hypergraph-product (QHP) codes. Similarly to QHP codes, the propose…

Single-shot and two-shot decoding with generalized bicycle codes
Hsiang-Ku Lin, Xingrui Liu, Pak Kau Lim +1
Generalized-bicycle (GB) and more general two-block group-algebra (2BGA) quantum error-correcting codes have naturally redundant minimum-weight stabilizer generators. To use this r…
