Mathematics of topological quantum computing

E Rowell, Z Wang - Bulletin of the American Mathematical Society, 2018 - ams.org
In topological quantum computing, information is encoded in “knotted” quantum states of
topological phases of matter, thus being locked into topology to prevent decay. Topological …

[HTML][HTML] Set-theoretic solutions of the Yang–Baxter equation and new classes of R-matrices

A Smoktunowicz, A Smoktunowicz - Linear Algebra and its Applications, 2018 - Elsevier
We describe several methods of constructing R-matrices that are dependent upon many
