La série des talks en informatique quantique continue avec des candidats au CNRS chez nous. Cette fois nous écouterons Christophe Vuillot.




We introduce quantum pin codes: a class of quantum CSS codes. Quantum pin codes are a vast generalization of quantum color codes and Reed-Muller codes. A lot of the structure and properties of color codes carries over to pin codes. Pin codes have gauge operators, an unfolding procedure and their stabilizers form multi-orthogonal spaces. This last feature makes them interesting for devising magic-state distillation protocols. We study examples of these codes and their properties. (https://arxiv.org/abs/1906.11394)
