Hardware-efficient quantum error correction via concatenated bosonic qubits. [PDF]

Nature
To solve problems of practical importance1,2, quantum computers probably need to incorporate quantum error correction, in which a logical qubit is redundantly encoded in many noisy physical qubits3, 4–5.

Quantum error correction below the surface code threshold. [PDF]

Nature
Quantum error correction1, 2, 3–4 provides a path to reach practical quantum computing by combining multiple physical qubits into a logical qubit, in which the logical error rate is suppressed exponentially as more qubits are added.

New perspectives on covariant quantum error correction [PDF]

Quantum, 2021
Covariant codes are quantum codes such that a symmetry transformation on the logical system could be realized by a symmetry transformation on the physical system, usually with limited capability of performing quantum error correction (an important case ...

Quantum error correction of qudits beyond break-even. [PDF]

Nature
Hilbert space dimension is a key resource for quantum information processing1,2. Not only is a large overall Hilbert space an essential requirement for quantum error correction, but a large local Hilbert space can also be advantageous for realizing gates

Quantum computer error structure probed by quantum error correction syndrome measurements

Physical Review Research
With quantum devices rapidly approaching qualities and scales needed for fault tolerance, the validity of simplified error models underpinning the study of quantum error correction needs to be experimentally evaluated.

Removing leakage-induced correlated errors in superconducting quantum error correction. [PDF]

Nat Commun, 2021
Quantum computing can become scalable through error correction, but logical error rates only decrease with system size when physical errors are sufficiently uncorrelated.

Mixed-State Quantum Phases: Renormalization and Quantum Error Correction [PDF]

Physical Review X, 2023
Open system quantum dynamics can generate a variety of long-range entangled mixed states, yet it has been unclear in what sense they constitute phases of matter.

Scalable Quantum Error Correction for Surface Codes Using FPGA [PDF]

International Conference on Quantum Computing and Engineering, 2023
A fault-tolerant quantum computer must decode and correct errors faster than they appear. The faster errors can be corrected, the more time the computer can do useful work. The Union-Find (UF) decoder is promising with an average time complexity slightly
