• openAccess   MDS, Hermitian almost MDS, and Gilbert–Varshamov quantum codes from generalized monomial-Cartesian codes 

      Barbero Lucas, Beatriz; Hernando, Fernando; Martín-Cruz, Helena; McGuire, Gary Springer Nature (2024-03-01)
      We construct new stabilizer quantum error-correcting codes from generalized monomial-Cartesian codes. Our construction uses an explicitly defined twist vector, and we present formulas for the minimum distance and dimension. ...
    • openAccess   Optimal (r,δ)-LRCs from monomial-Cartesian codes and their subfield-subcodes 

      Galindo, Carlos; Hernando, Fernando; Martín-Cruz, Helena Springer (2024-05-02)
      We study monomial-Cartesian codes (MCCs) which can be regarded as (r,δ)-locally recoverable codes (LRCs). These codes come with a natural bound for their minimum distance and we determine those giving rise to (r,δ)-optimal ...
    • openAccess   Stabilizer quantum codes defined by trace-depending polynomials 

      Galindo, Carlos; Hernando, Fernando; Martín-Cruz, Helena; Ruano, Diego Elsevier (2022-12-29)
      Quantum error-correcting codes with good parameters can be constructed by evaluating polynomials at the roots of the polynomial trace [18]. In this paper, we propose to evaluate polynomials at the roots of trace-depending ...
