Decoherence of the color code produces a mixed state with topological entanglement negativity ln 2 that corresponds to an emergent single toric code.
Measurement-induced entanglement in Tomonaga-Luttinger liquids is universal, conformally invariant, and arises from Born-rule averaging over conformally invariant boundary conditions in the CFT.
Local perturbations induce synthetic twist defects in the surface code; simplified spin and Majorana models plus numerics locate the driving quantum phase transition.
