Determination of the Semion Code Threshold using Neural Decoders
Santiago Varona, Miguel Angel Martin-Delgado
We compute the error threshold for the semion code, the companion of the Kitaev toric code with the same gauge symmetry group . The application of statistical mechani…

Quantum Error Correction with the Semion Code
Guillaume Dauphinais, Laura Ortiz, Santiago Varona +1
We present a full quantum error correcting procedure with the semion code: an off-shell extension of the double semion model. We construct open strings operators that recover the q…

Topological Phases in Nodeless Tetragonal Superconductors
Santiago Varona, Laura Ortiz, Oscar Viyuela +1
We compute the topological phase diagram of 2D tetragonal superconductors for the only possible nodeless pairing channels compatible with that crystal symmetry. Subject to a Zeeman…
