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…
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…
Geometry of the symplectic group and optimal EAQECC codes
Ruihu Li, Yuezhen Ren, Chaofeng Guan +1
A new type of link between geometry of symplectic group and entanglement-assisted (EA) quantum error-correcting codes (EAQECCs) is presented. Relations of symplectic subspaces and…
