    • openAccess   Entanglement-assisted quantum error-correcting codes over arbitrary finite fields 

      Galindo, Carlos; Hernando, Fernando; Matsumoto, Ryutaroh; Ruano, Diego Springer Verlag (2019)
      We prove that the known formulae for computing the optimal number of maximally entangled pairs required for entanglement-assisted quantum error-correcting codes (EAQECCs) over the binary field hold for codes over arbitrary ...

    • openAccess   Quasi-cyclic constructions of quantum codes 

      Galindo, Carlos; Hernando, Fernando; Matsumoto, Ryutaroh Elsevier (2018-07)
      We give sufficient conditions for self-orthogonality with respect to symplec- tic, Euclidean and Hermitian inner products of a wide family of quasi-cyclic codes of index two. We provide lower bounds for the symplectic ...
