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…

Topological orders with classical Lie group symmetries from coupling electron wires
Pak Kau Lim, Michael Mulligan, Jeffrey C. Y. Teo
We study the topological order that arises from chiral states with or edge-state symmetry. This extends our previous study of topological orders that de…
