A new approach to codeword stabilized quantum codes using the algebraic structure of modules
Douglas Frederico Guimarães Santiago, Geraldo Samuel Sena Otoni
In this work, we study the Codeword Stabilized Quantum Codes (CWS codes) a generalization of the stabilizers quantum codes using a new approach, the algebraic structure of modules,…
Non-Pauli Observables for CWS Codes
Douglas F. G. Santiago, Renato Portugal, Nolmar Melo
It is known that nonadditive quantum codes are more optimal for error correction when compared to stabilizer codes. The class of codeword stabilized codes (CWS) provides tools to o…
Decoder for Nonbinary CWS Quantum Codes
Nolmar Melo, Douglas F. G. Santiago, Renato Portugal
We present a decoder for nonbinary CWS quantum codes using the structure of union codes. The decoder runs in two steps: first we use a union of stabilizer codes to detect a sequenc…
