论文摘要
我们表明，将相关阶段添加到最近开发的随机动力学去耦脉冲序列的方法中[物理评论字母122，200403（2019）]可以改善其在量子传感方面的性能。特别是，通过将基本脉冲单元的相对阶段相关联，我们可以改善由于$π$脉冲缺陷而引起的信号失真的抑制和由于有限宽度$π$脉冲而引起的虚假响应。这提高了量子传感器的选择性，例如基于钻石中NV中心的量子传感器。
We show that the addition of correlated phases to the recently developed method of randomized dynamical decoupling pulse sequences [Physical Review Letters 122, 200403 (2019)] can improve its performance in quantum sensing. In particular, by correlating the relative phases of basic pulse units in dynamical decoupling sequences, we are able to improve the suppression of the signal distortion due to $π$ pulse imperfections and spurious responses due to finite-width $π$ pulses. This enhances selectivity of quantum sensors such as those based on NV centers in diamond.
