Quantum Bicycle LDPC Codes with High from Divisor-Driven Search
Liangdong Lu, Guanmin Guo, Yang Liu +1
Bicycle (two-block circulant) quantum low-density parity-check (LDPC) codes include some of the best known small quantum codes, yet their design has relied on group-algebra formula…
Quantum Codes from -Nearly Self-Orthogonal Linear Codes via Jordan Canonical Form over
Liangdong Lu, Ruipan Yang, Yang Liu +2
The paper presents a Jordan‑canonical‑form method to build q‑ary quantum stabilizer codes from any classical linear code over \(\mathbb{F}_{q^2}\) without requiring self‑orthogonal…
Construction of EAQECCs with imperfect ebits
Guanmin Guo, Ruihu Li
We generalize the stabilizer formalism for entanglement-assisted quantum error-correcting codes with noisy ebits (EAQECCs-Ne) from the binary case to the general -ary case, wher…
Stabilizer Formalism for EAQECCs with Noise ebits
Ruihu Li, Guanmin Guo, Yang Liu +1
We introduce a stabilizer formalism for EAQECCs with noise ebits, using special subgroups of product groups of two Pauli groups. This formalism includes the two coding schemes,give…
