Title: “The twists and boundaries of the color code”

Abstract: Exploring the different features of a topological phase may allow us to find new ways of finding fault-tolerant logical gates for quantum computing. Phases with a high degree of symmetry in the physics of their low-energy excitations are particularly interesting in this respect. I will talk about the numerous symmetries of the color code, and the different topological defects and boundaries that emerge as a consequence. The defects we discuss can be exploited to achieve different computational protocols with the color code model.
