Bias-tailored quantum LDPC codes

Joschka Roffe et al.

Summary: Bias-tailoring allows quantum error correction codes to exploit qubit noise asymmetry. Recently, a modified form of the surface code, the XZZX code, has shown improved performance under biased noise. This study demonstrates that quantum low density parity check codes can also be similarly bias-tailored. The authors introduce a bias-tailored lifted product code construction that expands bias-tailoring methods beyond 2D topological codes and evaluate its performance numerically.

Realizing repeated quantum error correction in a distance-three surface code

Sebastian Krinner et al.

Summary: This study demonstrates quantum error correction using the surface code and implements protection of logical qubits using 17 physical qubits in a superconducting circuit. By repeatedly executing error-correction cycles, measuring and decoding error syndromes, and applying post-processing corrections, repeated, fast, and high-performance quantum error correction is achieved.

Protecting a bosonic qubit with autonomous quantum error correction

Jeffrey M. Gertler et al.

Summary: In this study, a logical qubit encoded in multi-photon states of a superconducting cavity is protected with autonomous correction of certain quantum errors by tailoring the dissipation it is exposed to. The passive protocol implemented with continuous-wave control fields autonomously corrects single-photon-loss errors and increases the coherence time of the bosonic qubit by over a factor of two. This approach offers a resource-efficient alternative or supplement to active QEC in future quantum computing architectures.

The XZZX surface code

J. Pablo Bonilla Ataides et al.

Summary: Research shows that using the XZZX code for fault-tolerant quantum computation offers remarkable performance and can surpass the hashing bound in experimentally relevant noise parameters. In cases where qubit dephasing is the dominant noise, this code has a practical decoder and exceeds previous thresholds. The code demonstrates favorable sub-threshold resource scaling and maintains advantages when performing fault-tolerant quantum computation, showing better performance and requiring fewer resources compared to the surface code.
