Diagnostics of mixed-state topological order and breakdown of quantum memory
Ruihua Fan, Yimu Bao, Ehud Altman +1
Topological quantum memory can protect information against local errors up to finite error thresholds. Such thresholds are usually determined based on the success of decoding algor…

Mixed-state topological order and the errorfield double formulation of decoherence-induced transitions
Yimu Bao, Ruihua Fan, Ashvin Vishwanath +1
We develop an effective field theory characterizing the impact of decoherence on states with abelian topological order and on their capacity to protect quantum information. The dec…
