Contribution & Novelties
The talk presents a novel approach to constructing non-invertible symmetries on tensor product Hilbert spaces by combining gauging of non-invertible symmetries with ZX calculus. This provides explicit lattice realizations of symmetries that were previously only studied at the abstract level. The speaker also highlights the subtlety of mixing with lattice translations, which is an important consideration for exact lattice realizations.
