We present a novel method for fabricating highly customizable three-dimensional structures hosting quantum sensors based on nitrogen vacancy (NV) centers using two-photon polymerization. This approach overcomes challenges associated with structuring traditional single-crystal quantum sensing platforms and enables the creation of complex, fully three-dimensional, sensor assemblies with submicroscale resolutions (down to 400 nm) and large fields of view (>1 mm). By embedding NV center-containing nanoparticles in exemplary structures, we demonstrate high sensitivity optical sensing of temperature and magnetic fields at the microscale. Our work showcases the potential for integrating quantum sensors with advanced manufacturing techniques, facilitating the incorporation of sensors into existing microfluidic and electronic platforms, and opening new avenues for widespread utilization of quantum sensors in various applications.
我们提出了一种基于双光子聚合制造高度可定制的三维结构的新方法，该结构包含基于氮空位（NV）中心的量子传感器。这种方法克服了与构建传统单晶量子传感平台相关的挑战，并能够创建具有亚微米级分辨率（低至400纳米）和大视场（>1毫米）的复杂全三维传感器组件。通过将含NV中心的纳米颗粒嵌入示例结构中，我们展示了在微观尺度上对温度和磁场的高灵敏度光学传感。我们的工作展示了将量子传感器与先进制造技术集成的潜力，有助于将传感器纳入现有的微流体和电子平台，并为量子传感器在各种应用中的广泛应用开辟新途径。
