• Title: Asymmetric quantum codes on non-orientable surfaces
• Abstract summary: We prove that if the genus $g$ of a non-orientable surface is even $(g=2h)$, the parameters of the corresponding AQSC are equal to the parameters of a surface code obtained from an orientable surface of genus $h$. We also show that the new surface code constructed on a $p, q$ tessellation over $S$ has the ratio $k/n$ better than the ratio of an AQSC constructed on the same $p, q$ tessellation over an orientable surface of genus $g$.

• Abstract: In this paper, we construct new families of asymmetric quantum surface codes (AQSCs) over non-orientable surfaces of genus $g\geq 2$ by applying tools of hyperbolic geometry. More precisely, we prove that if the genus $g$ of a non-orientable surface is even $(g=2h)$, then the parameters of the corresponding AQSC are equal to the parameters of a surface code obtained from an orientable surface of genus $h$. Additionally, if $S$ is a non-orientable surface of genus $g$, we show that the new surface code constructed on a $\{p, q\}$ tessellation over $S$ has the ratio $k/n$ better than the ratio of an AQSC constructed on the same $\{p, q\}$ tessellation over an orientable surface of the same genus $g$.

  The observables associated with a quantum system $S$ form a non-commutative algebra $mathcal A_S$. It is assumed that a density matrix $rho$ can be determined from the expectation values of observables. Abelian algebras do not have inner automorphisms, so the measurement apparatus can determine mean values of observables.

• Surface Code Design for Asymmetric Error Channels [55.41644538483948]
  We introduce a surface code design based on the fact that bit flip and phase flip errors in quantum systems are asymmetric. We show that, compared to symmetric surface codes, our asymmetric surface codes can provide almost double the pseudo-threshold rates. As the asymmetry of the surface code increases, the advantage in the pseudo-threshold rates begins to saturate for any degree of asymmetry in the channel.
