探测和控制核自旋纳米系综对于核磁共振（NMR）光谱学的进一步发展和新兴的固态量子技术至关重要。在这里，我们提出了一个1000纳米厚的金刚石层的制造组成的13 C核自旋掺杂氮空位中心（NV）嵌入在无自旋12 C晶体基质。在该层附近的单个NV用于13 C自旋的极化和其磁化的读出。我们展示了一种方法，通过使用射频脉冲的相干控制的几十个核自旋，并显示基本的相干控制实验，拉比振荡和拉姆齐光谱，但任何NMR脉冲序列可以实现。这里所示的结果是实现基于核自旋的量子模拟器的重要一步。
Detecting and controlling nuclear spin nano-ensembles is crucial for the further development of nuclear magnetic resonance (NMR) spectroscopy and for the emerging solid state quantum technology. Here we present the fabrication of a ≈1 nanometre thick diamond layer consisting of13C nuclear spins doped with nitrogen-vacancy centres (NV) embedded in a spin-free12C crystal matrix. A single NV in the vicinity of the layer is used for polarization of the13C spins and the readout of their magnetization. We demonstrate a method for coherent control of few tens of nuclear spins by using radio frequency pulses, and show the basic coherent control experiments, Rabi oscillations and Ramsey spectroscopy, though any NMR pulse sequence can be implemented. The results shown here present an important step towards the realization of a nuclear spin based quantum simulator.
