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 …

We study states with intrinsic topological order subjected to local decoherence from the
perspective of separability, ie, whether a decohered mixed state can be expressed as an …

Quantum error correction (QEC) codes protect quantum information from errors due to
decoherence. Many of them also serve as prototypical models for exotic topological …

Tailored topological stabilizer codes in two dimensions have been shown to exhibit high-
storage-threshold error rates and improved subthreshold performance under biased Pauli …

A bstract This work investigates the gapped interfaces of 3+ 1d fracton phases of matter
using foliated gauge theories and lattice models. We analyze the gapped boundaries and …

Subsystem symmetry has emerged as a powerful organizing principle for unconventional
quantum phases of matter, most prominently fracton topological orders. Here, we focus on a …

Measurements can detect errors in a decohered quantum memory allowing active error
correction to increase the memory time. Previous understanding of this mechanism has …

Topologically-ordered phases are stable to local perturbations, and topological quantum
error-correcting codes enjoy thresholds to local errors. We connect the two notions of …

In this paper, we introduce an algorithm for extracting topological data from translation
invariant generalized Pauli stabilizer codes in two-dimensional systems, focusing on the …

Fracton codes host unconventional topological states of matter and are promising for fault-
tolerant quantum computation due to their large coding space and strong resilience against …
