Quantum error correction for quantum memories

BM Terhal - Reviews of Modern Physics, 2015 - APS
Active quantum error correction using qubit stabilizer codes has emerged as a promising,
but experimentally challenging, engineering program for building a universal quantum …

Quantum memories at finite temperature

BJ Brown, D Loss, JK Pachos, CN Self… - Reviews of Modern Physics, 2016 - APS

coherence for macroscopic time scales, even at finite temperature. Quantum error correction …

Toward a classification of mixed-state topological orders in two dimensions

TD Ellison, M Cheng - PRX Quantum, 2025 - APS
The classification and characterization of topological phases of matter is well understood for
ground states of gapped Hamiltonians that are well isolated from the environment. However …

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 …

Noisy approach to intrinsically mixed-state topological order

R Sohal, A Prem - PRX Quantum, 2025 - APS
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 …

[HTML][HTML] Dynamically generated logical qubits

MB Hastings, J Haah - Quantum, 2021 - quantum-journal.org
We present a quantum error correcting code with $\textit {dynamically generated logical
qubits} $. When viewed as a subsystem code, the code has no logical qubits. Nevertheless …

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 …

A fault-tolerant honeycomb memory

C Gidney, M Newman, A Fowler, M Broughton - Quantum, 2021 - quantum-journal.org
Abstract Recently, Hastings & Haah introduced a quantum memory defined on the
honeycomb lattice. Remarkably, this honeycomb code assembles weight-six parity checks …

Modeling and simulating the noisy behavior of near-term quantum computers

K Georgopoulos, C Emary, P Zuliani - Physical Review A, 2021 - APS
Noise dominates every aspect of near-term quantum computers, rendering it exceedingly
difficult to carry out even small computations. In this paper we are concerned with the …

Engineering 3d floquet codes by rewinding

A Dua, N Tantivasadakarn, J Sullivan, TD Ellison - PRX Quantum, 2024 - APS
Floquet codes are a novel class of quantum error-correcting codes with dynamically
generated logical qubits arising from a periodic schedule of noncommuting measurements …
