Quantum error correction may delay, but also cause, entanglement sudden death
, 2008 Dissipation may cause two initially entangled qubits to evolve into a separable state in a finite time. This behavior is called entanglement sudden death (ESD). We study to what extent quantum error correction can combat ESD.

An Efficient Analytical Approach for Error Assessment in Quantum Circuits
IEEE AccessOne of the most important challenges in constructing large-scale quantum computers is handling the high error rates in quantum systems. Using error correction codes and frequently applying error correction on qubits is a common approach to compete with ...

Quantum error correction with the semion code [PDF]
New Journal of Physics, 2019 Abstract We present a full quantum error correcting procedure with the semion code: an off-shell extension of the double-semion model. We construct open-string operators that recover the quantum memory from arbitrary errors and closed-string operators that implement the basic logical operations for information processing. Physically, the

Comparing the Overhead of Topological and Concatenated Quantum Error Correction
, 2013 This work compares the overhead of quantum error correction with concatenated and topological quantum error-correcting codes. To perform a numerical analysis, we use the Quantum Resource Estimator Toolbox (QuRE) that we recently developed. We use QuRE to

Quantum computing with nearest neighbor interactions and error rates over 1%
, 2010 Large-scale quantum computation will only be achieved if experimentally implementable quantum error correction procedures are devised that can tolerate experimentally achievable error rates.

Blueprint for fault-tolerant quantum computation with Rydberg atoms [PDF]
, 2017 We present a blueprint for building a fault-tolerant universal quantum computer with Rydberg atoms. Our scheme, which is based on the surface code, uses individually addressable, optically trapped atoms as qubits and exploits electromagnetically induced ...

All-optical cat-code quantum error correction
Physical Review Research, 2022 The cat code is a promising encoding scheme for bosonic quantum error correction as it allows for correction against losses—the dominant error mechanism in most bosonic systems.
