Projected logical ensembles in surface codes via the random-matrix theory of quantum dots
Mircea Bejan, Jan Behrends, Max McGinley +1
Measurements underpin active quantum error correction (QEC) and have been recognized as a source of novel measurement-induced many-body phenomena. Here, we study the statistical pr…

SymTFT out of equilibrium: from time crystals to braided drives and Floquet codes
Vedant Motamarri, Campbell McLauchlan, Benjamin Béri
Symmetry Topological Field Theory (SymTFT) is a framework to capture universal features of quantum many-body systems by viewing them as a boundary of topological order in one highe…

Dynamical Magic Transitions in Monitored Clifford+T Circuits
Mircea Bejan, Campbell McLauchlan, Benjamin Béri
The classical simulation of highly-entangling quantum dynamics is conjectured to be generically hard. Thus, recently discovered measurement-induced transitions between highly entan…
