@article{Wu2022ErasureCF, title={Erasure conversion for fault-tolerant quantum computing in alkaline earth Rydberg atom arrays}, author={Yue Wu and Shimon Kolkowitz and Shruti Puri and Jeff D. Thompson}, journal={Nature Communications}, year={2022}, volume={13} }

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. Recently, the development of error correcting codes tailored to particular physical noise models has helped relax these requirements. In this work, we propose a qubit encoding and gate protocol for 171Yb neutral atom qubits that converts the dominant physical errors into…
