Nuclei surrounding single electron spins are valuable resources for quantum technology. For application in this area, one is often interested in weakly coupled nuclei with coupling strength on the order of a few 10–100 kHz. In this paper, we compare methods to address single nuclear spins with this type of hyperfine coupling to a single electron spin. To achieve the required spectral resolution, we specifically focus on two methods, namely dynamical decoupling and correlation spectroscopy. We demonstrate spectroscopy of two single nuclear spins and present a method to derive components of their hyperfine coupling tensor from those measurements.

通过中心电子自旋解决单核自旋量子记忆

围绕单电子自旋的原子核是量子技术的宝贵资源。对于该领域的应用，人们通常对耦合强度约为 10-100 kHz 的弱耦合原子核感兴趣。在本文中，我们比较了通过这种超精细耦合到单个电子自旋来解决单核自旋的方法。为了达到所需的光谱分辨率，我们特别关注两种方法，即动态去耦和相关光谱。我们演示了两个单核自旋的光谱学，并提出了一种从这些测量中推导出其超精细耦合张量分量的方法。
