Microscopic study of topological phase transitions: Percolation point of view
Keisuke Kataoka, Ikuo Ichinose
We investigate microscopic mechanisms underlying decoherence-induced transitions between topologically ordered states. As a first case study, we analyze the color code using topolo…

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…
