Fate of average symmetry-protected topological states under symmetry-preserving quantum operations
Yoshihito Kuno, Takahiro Orito
The fate of average symmetry-protected topological (ASPT) states based on the one-dimensional cluster state is investigated by using the Choi mapping, namely, the doubled Hilbert-s…
Hierarchy of mixed symmetry protected topological states in extended cluster states under subsystem decoherence
Yoshihito Kuno, Takahiro Orito
We study the effect of subsystem decoherence to an extended cluster state which is a symmetry protected topological (SPT) phase. The model includes many subsystem symmetries.…
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…
Continuous Reset-Induced Phase Transition in Measurement-Free Random Quantum Circuits
Hinata Yokoyama, Kengo Anzai, Dina Syverud-Lindland +2
We study a random unitary quantum circuit with only reset channels, which has high feasibility for real quantum devices. In particular, we investigate the many-body statistical phy…
