论文摘要
与Pauli错误相比，擦除或具有已知位置的错误是量子错误校正代码的错误类型。将物理噪声转换为擦除可以显着改善量子误差校正的性能。在这里，我们应用了Wu，Kolkowitz，Puri和Thompson提出的亚稳态原子状态，将量子置于亚稳态的原子态中，以进行擦除转换的想法。通讯。 13，4657（2022）]，用于被困的离子。我们建议一种用于亚稳态的捕获量子尺的擦除转换方案，并开发出各种类型错误的详细模型。然后，我们比较在各种物理约束下地面代码上的地面和亚稳定量子位的逻辑性能，并得出结论，当可实现的激光功率较高时，对于亚稳态量子，亚稳定量子可能会超过地面吨位。
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. Here we apply the idea of performing erasure conversion by encoding qubits into metastable atomic states, proposed by Wu, Kolkowitz, Puri, and Thompson [Nat. Comm. 13, 4657 (2022)], to trapped ions. We suggest an erasure-conversion scheme for metastable trapped-ion qubits and develop a detailed model of various types of errors. We then compare the logical performance of ground and metastable qubits on the surface code under various physical constraints, and conclude that metastable qubits may outperform ground qubits when the achievable laser power is higher for metastable qubits.
