摘要

基于固体自旋的宽场量子传感和成像技术因其在纳米尺度上以高灵敏度探测相对物理量的能力而引起了广泛的关注。然而，光学衍射极限阻碍了空间分辨率的提高。在这项工作中，我们利用盲结构照明显微镜进行了金刚石中氮空位（NV）中心的宽视场量子传感。在不需要预先了解激发光场的情况下，NV中心成像的空间分辨率比传统显微镜提高了1.8倍。结合自旋操作和检测，进行超分辨率NV中心传感，揭示纳米器件的光学和电学特性。该工作的高空间分辨率和可行性将促进量子传感在纳米科学中的应用。

Super-resolution wide-field quantum sensing

Wide-field quantum sensing and imaging with solid-state spins has attracted wide interest for its ability to detect relative physical quantities with high sensitivity at nanoscale. However, the optical diffraction limit hinders the improvement in spatial resolution. In this work, we utilize blind structured illumination microscopy to perform wide-field quantum sensing with nitrogen-vacancy (NV) center in diamond. Without the requirement of prior knowledge of excitation light field, the spatial resolution of NV centers imaging is enhanced by 1.8-fold in comparison with conventional microscopy. Combined with spin manipulation and detection, super-resolution NV center sensing is subsequently performed to reveal the optical and electrical properties of nanodevice. The high spatial resolution and feasibility of this work will promote the applications of quantum sensing in nanoscience.

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
