Exact Recovery for Non-Abelian Surface Codes
Alison Warman, Nathanan Tantivasadakarn, Sakura Schafer-Nameki
We study exact recovery for non-Abelian topological surface codes based on the quantum double of any finite group . We determine an orthogonal error basis, that is compri…
-Manifolds from 4d Quivers
Andreas P. Braun, Oscar Lewis, Matteo Sacchi +1
Inspired by quantum field-theoretic constructions of 4d quiver gauge theories that flow to superconformal field theories (SCFTs), we construct 7d manifolds of …
Proliferation Transitions for Non-Abelian Anyons
Sakura Schafer-Nameki, Yunqin Zheng, Andrea Antinucci
We construct phase transitions that proliferate condensable anyons in general 2+1d topological orders, including non-abelian ones. The central tool that provides a systematic appro…
Non-Invertible Symmetries Mixing with Witt Non-Trivial Quantum Cellular Automata
Kansei Inamura, Oskar Wojdel, Lukasz Fidkowski +1
Self-dualities and the stacking of symmetry-protected topological (SPT) phases are basic operations on quantum many-body systems. For a one-form symmetry in 3+1d the…
Twin Algebras: Condensable Algebras beyond Anyons
Yuhan Gai, Sakura Schafer-Nameki, Alison Warman
Condensable algebras in 2+1d non-chiral topological orders characterize gapped boundary conditions and interfaces. Applied to the Symmetry Topological Field Theory, they allow clas…
Non-Invertible Symmetries on Tensor-Product Hilbert Spaces and Quantum Cellular Automata
Rui Wen, Kansei Inamura, Sakura Schafer-Nameki
We investigate realizations of (1+1)-dimensional fusion category symmetries on tensor-product Hilbert spaces, allowing for mixing with quantum cellular automata (QCAs). It was argu…
