Mutual information between non-contractible regions on the torus fully classifies long-range nonstabilizerness for toric-code states but leaves a finite subset undetected in the doubled-Fibonacci string-net model.
Classical simulation algorithms for low-magic adaptive quantum circuits with high Pauli measurement rates, demonstrated on all-to-all monitored circuits with sub-extensive T-gates to study measurement-induced phase transitions.
Monitored random quantum circuits lack divergent multipartite entanglement at criticality unlike standard critical systems, but two-site measurements with a protection mechanism enable genuinely multipartite entangled phases.
