论文摘要
我们通过一种基于相干量子控制的新型荧光照相技术来证明钻石中氮空位中心的超分辨率定位。通过基于脉冲磁场梯度的量子相编码来实现照片处理。然后，我们执行超分辨率成像，并在扫描共聚焦显微镜下获得比1.4 nm更好的本地化精度。最后，我们表明编码的量子相在分辨率上起主要作用，并且在我们当前的实验条件下可以实现0.15 nm的分辨率。该方法可以基于多个耦合缺陷旋转，以尺寸为Qubits的尺度和控制。
We demonstrate the super-resolution localization of the nitrogen vacancy centers in diamond by a novel fluorescence photoswitching technique based on coherent quantum control. The photoswitching is realized by the quantum phase encoding based on pulsed magnetic field gradient. Then we perform super-resolution imaging and achieve a localizing accuracy better than 1.4 nm under a scanning confocal microscope. Finally, we show that the quantum phase encoding plays a dominant role on the resolution, and a resolution of 0.15 nm is achievable under our current experimental condition. This method can be applied in subnanometer scale addressing and control of qubits based on multiple coupled defect spins.
