论文摘要
我们使用基于梯度的优化方案来查找嘈杂的逻辑两Q Qubit纠缠栅极之间交织在一起的单量旋转,以抑制两数Qubit Gate中的任意逻辑和泄漏错误。我们展示了序列保真度如何受到单量操作中缺陷的影响,以及逻辑和泄漏噪声的各种相对强度。我们的方法是完全综合的,无关紧要的,无论实验实现细节如何,都可以应用于任何两倍的系统。
We use a gradient-based optimization scheme to find single-qubit rotations to be interwoven between timesteps of a noisy logical two-qubit entangling gate in order to suppress arbitrary logical and leakage errors in the two-qubit gate. We show how the sequence fidelity is affected by imperfections in the single-qubit operations, as well as by various relative strengths of the logical and leakage noise. Our approach is completely general and system-independent, allowing for application to any two-qubit system regardless of the experimental implementation details.
