Understanding the behavior of topologically ordered lattice systems at finite temperature is a way of assessing their potential as fault-tolerant quantum memories. We compute the natural extension of the topological entanglement entropy for T>0, namely, the subleading correction I{sub topo} to the area law for mutual information. Its dependence on T can be written, for Abelian Kitaev models, in terms of information-theoretical functions and readily identifiable scaling behavior, from which the…

### Defects in topologically ordered lattice models

It is shown that the anyonic data of twists in Kitaev’s toric code model can be extracted and entropically inspire fragile glassy dynamics in the system to improve the coherence times of quantum information encoded in the ground state of the lattice.

### A witness for topological order and stable quantum memories in Abelian anyonic systems

A novel parameter, the anyonic topological entropy, designed to detect the error correcting phase of a topological memory, defined using the states of the anyon occupations, which can be calculated solely from classical probability distributions.

### Towards unambiguous calculation of the topological entropy for mixed states

Calculation of topological order parameters, such as the topological entropy and topological mutual information, is used to determine whether states possess topological order. Their calculation is

Thermalisation is a probabilistic process. As such, it is generally expected that when we increase the temperature of a system its classical behaviour dominates its quantum coherences. By employing

This Letter shows that the holographic principle not only emerges in the search for new Planck-scale laws but also in lattice models of classical and quantum physics: the information contained in part of a system in thermal equilibrium obeys an area law.
