Microscopic study of topological phase transitions: Percolation point of view
Keisuke Kataoka, Ikuo Ichinose
The paper investigates how decoherence drives transitions between topologically ordered quantum states by applying percolation theory, introducing quasi‑local topological entanglem…

Decohered color code and emerging mixed toric code by anyon proliferation: Topological entanglement negativity perspective
Keisuke Kataoka, Yoshihito Kuno, Takahiro Orito +1
We study how the color code under decoherence gives rise to an intrinsic mixed-state topological order (imTO), which has no counterpart in pure ground states of local gapped Hamilt…
