Nitrogen vacancy (NV) centers in diamonds is a promising system for quantum information processing and quantum sensing, and the control of the quantum state is essential for practical applications. In this study, we demonstrate a control of all the three transitions among the ground state sublevels of NV centers by applying external magnetic driving fields. To address the states of a specific NV axis among the four axes, we apply a magnetic field orthogonal to the NV axis. We control two transitions by microwave pulses and the remaining transition by radio frequency pulses. In particular, we investigate the dependence of Rabi oscillations on the frequency and intensity of the radio frequency pulses. Our results pave the way for a novel control of NV centers for the realization of quantum information processing and quantum sensing.

通过施加外部磁驱动场控制金刚石中氮空位中心基态流形之间的所有跃迁

金刚石中的氮空位 (NV) 中心是用于量子信息处理和量子传感的有前途的系统，并且量子态的控制对于实际应用至关重要。在这项研究中，我们通过应用外部磁驱动场证明了对 NV 中心基态子能级之间所有三个转换的控制。为了解决四个轴中特定 NV 轴的状态，我们应用了与 NV 轴正交的磁场。我们通过微波脉冲控制两个跃迁，并通过射频脉冲控制其余跃迁。特别是，我们研究了 Rabi 振荡对射频脉冲的频率和强度的依赖性。我们的结果为实现量子信息处理和量子传感的 NV 中心的新型控制铺平了道路。
