Additive Conjucyclic Codes over $\F_{q^2}$: Trace Correspondence and Applications to Quantum Codes
Jingjie Lv, Xian Lian, Ruihu Li +1
Additive conjucyclic codes over $\F_{q^2}$ are closed under the conjugated cyclic shift and play an important role in constructing quantum error-correcting codes (QECCs). However,…

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…
