Optimizing Quantum Error-Correction Protocols with Erasure Qubits

PRX Quantum
Erasure qubits offer a promising avenue toward reducing the overhead of quantum error correction (QEC) protocols. However, they require additional operations, such as erasure checks, that may add extra noise and increase the run-time of QEC protocols. To

LEACE: Perfect linear concept erasure in closed form [PDF]

Neural Information Processing Systems, 2023
Concept erasure aims to remove specified features from an embedding. It can improve fairness (e.g. preventing a classifier from using gender or race) and interpretability (e.g. removing a concept to observe changes in model behavior).

High-Threshold Codes for Neutral-Atom Qubits with Biased Erasure Errors [PDF]

Physical Review X, 2023
The requirements for fault-tolerant quantum error correction can be simplified by leveraging structure in the noise of the underlying hardware. In this work, we identify a new type of structured noise motivated by neutral atom qubits, biased erasure ...

Erasure conversion for fault-tolerant quantum computing in alkaline earth Rydberg atom arrays [PDF]

Nature Communications, 2022
Executing quantum algorithms on error-corrected logical qubits is a critical step for scalable quantum computing, but the requisite numbers of qubits and physical error rates are demanding for current experimental hardware.

Fault-tolerant quantum architectures based on erasure qubits [PDF]

Physical Review Research, 2023
The overhead of quantum error correction (QEC) poses a major bottleneck for realizing fault-tolerant computation. To reduce this overhead, we exploit the idea of erasure qubits, relying on an efficient conversion of the dominant noise into erasures at ...

Quantum Sensing with Erasure Qubits. [PDF]

Physical Review Letters, 2023
The dominant noise in an "erasure qubit" is an erasure-a type of error whose occurrence and location can be detected. Erasure qubits have potential to reduce the overhead associated with fault tolerance.

MANNER: Multi-View Attention Network For Noise Erasure [PDF]

IEEE International Conference on Acoustics, Speech, and Signal Processing, 2022
In the field of speech enhancement, time domain methods have difficulties in achieving both high performance and efficiency. Recently, dual-path models have been adopted to represent long sequential features, but they still have limited representations ...

Quantum Error Correction with Metastable States of Trapped Ions Using Erasure Conversion [PDF]

PRX Quantum, 2022
Erasures, or errors with known locations, are a more favorable type of error for quantum error-correcting codes than Pauli errors. Converting physical noise into erasures can significantly improve the performance of quantum error correction.
