Fracton phases of matter

M Pretko, X Chen, Y You - International Journal of Modern Physics …, 2020 - World Scientific
Fractons are a new type of quasiparticle which are immobile in isolation, but can often move
by forming bound states. Fractons are found in a variety of physical settings, such as spin …

The XZZX surface code

JP Bonilla Ataides, DK Tuckett, SD Bartlett… - Nature …, 2021 - nature.com
Performing large calculations with a quantum computer will likely require a fault-tolerant
architecture based on quantum error-correcting codes. The challenge is to design practical …

Subsystem non-invertible symmetry operators and defects

W Cao, L Li, M Yamazaki, Y Zheng - SciPost Physics, 2023 - scipost.org
We explore non-invertible symmetries in two-dimensional lattice models with subsystem
$\mathbb Z_2 $ symmetry. We introduce a subsystem $\mathbb Z_2 $-gauging procedure …

Fractons, dipole symmetries and curved spacetime

L Bidussi, J Hartong, E Have, J Musaeus, S Prohazka - SciPost Physics, 2022 - scipost.org
We study complex scalar theories with dipole symmetry and uncover a no-go theorem that
governs the structure of such theories and which, in particular, reveals that a Gaussian …

Anyon condensation and the color code

MS Kesselring, JC Magdalena de la Fuente… - PRX Quantum, 2024 - APS
The manipulation of topologically ordered phases of matter to encode and process quantum
information forms the cornerstone of many approaches to fault-tolerant quantum computing …

Pymatching: A python package for decoding quantum codes with minimum-weight perfect matching

O Higgott - ACM Transactions on Quantum Computing, 2022 - dl.acm.org
This article introduces PyMatching, a fast open-source Python package for decoding

Practical quantum error correction with the XZZX code and Kerr-cat qubits

AS Darmawan, BJ Brown, AL Grimsmo, DK Tuckett… - PRX Quantum, 2021 - APS
The development of robust architectures capable of large-scale fault-tolerant quantum
computation should consider both their quantum error-correcting codes and the underlying …

Floquet codes without parent subsystem codes

M Davydova, N Tantivasadakarn, S Balasubramanian - PRX Quantum, 2023 - APS
We propose a new class of error-correcting dynamic codes in two and three dimensions that
has no explicit connection to any parent subsystem code. The two-dimensional code, which …

Fault-Tolerant Thresholds for the Surface Code in Excess of under Biased Noise

DK Tuckett, SD Bartlett, ST Flammia, BJ Brown - Physical review letters, 2020 - APS
Noise in quantum computing is countered with quantum error correction. Achieving optimal
performance will require tailoring codes and decoding algorithms to account for features of …

Topological defect networks for fractons of all types

D Aasen, D Bulmash, A Prem, K Slagle… - Physical Review …, 2020 - APS
Fracton phases exhibit striking behavior which appears to render them beyond the standard
topological quantum field theory (TQFT) paradigm for classifying gapped quantum matter …
