Quantum memories at finite temperature
To use quantum systems for technological applications one first needs to preserve their
coherence for macroscopic time scales, even at finite temperature. Quantum error correction …

Long-range entanglement from measuring symmetry-protected topological phases
A fundamental distinction between many-body quantum states are those with short-and long-
range entanglement (SRE and LRE). The latter cannot be created by finite-depth circuits …

Towards classification of Fracton phases: the multipole algebra
A Gromov - Physical Review X, 2019 - APS
We present an effective field theory approach to the fracton phases. The approach is based
on the notion of a multipole algebra. It is an extension of space (time) symmetries of a …

Glassy quantum dynamics in translation invariant fracton models
We investigate relaxation in the recently discovered “fracton” models and discover that these
models naturally host glassy quantum dynamics in the absence of quenched disorder. We …

Fractal symmetries: Ungauging the cubic code
DJ Williamson - Physical Review B, 2016 - APS
Gauging is a ubiquitous tool in many-body physics. It allows one to construct highly
entangled topological phases of matter from relatively simple phases and to relate certain …
