RT info:eu-repo/semantics/article T1 Entanglement-assisted quantum error-correcting codes over arbitrary finite fields A1 Galindo, Carlos A1 Hernando, Fernando A1 Matsumoto, Ryutaroh A1 Ruano Benito, Diego AB 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 finite fields as well. We also give a Gilbert-Varshamov bound for EAQECCs and constructions of EAQECCs coming from punctured self-orthogonal linear codes which are valid for any finite field.
