Noisy approach to intrinsically mixed-state topological order
We propose a general framework for studying two-dimensional (2D) topologically ordered
states subject to local correlated errors and show that the resulting mixed state can display …

Symmetry-Enforced Entanglement in Maximally Mixed States
Entanglement in quantum many-body systems is typically fragile to interactions with the
environment. Generic unital quantum channels, for example, have the maximally mixed state …

Decoherence and wavefunction deformation of non-Abelian topological order
The effect of decoherence on topological order (TO) has been most deeply understood for
the toric code, the paragon of Abelian TOs. We show that certain non-Abelian TOs can be …

An analog of topological entanglement entropy for mixed states
We propose the convex-roof extension of quantum conditional mutual information (" co
(QCMI)") as a diagnostic of long-range entanglement in a mixed state. We focus primarily on …

Universal microscopic descriptions for statistics of particles and extended excitations
Statistics of excitations play an essential role in understanding phases of matter. In this
paper, we introduce a universal method for studying the generalized statistics of Abelian …
