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 ${\mathbb{Z}}_p$ one-form symmetry in 3+1d the…
