电子电路附近单个顺磁缺陷的纳米尺度定位是实现具有强自旋-微波光子耦合的混合量子器件的重要一步。在这里，我们展示了一个阵列的个别NV中心附近的金属纳米线沉积在衬底上的金刚石的制造。我们确定每个NV中心的相对位置，精度为10纳米，使用它作为矢量磁力计来测量通过直流电流通过导线产生的磁场。
The nanoscale localization of individual paramagnetic defects near an electrical circuit is an important step for realizing hybrid quantum devices with strong spin-microwave photon coupling. Here, we demonstrate the fabrication of an array of individual NV centers in diamond near a metallic nanowire deposited on top of the substrate. We determine the relative position of each NV center with $\sim$10\,nm accuracy, using it as a vector magnetometer to measure the field generated by passing a dc current through the wire.
