论文摘要
钻石中的氮空位（NV）中心是一个有前途的量子信息处理和量子传感的系统，量子状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性驱动场来证明NV中心基态底层层之间的所有三个过渡的控制。为了解决四个轴中特定NV轴的状态，我们将磁场正交应用于NV轴。我们通过微波脉冲控制了两个过渡，并通过射频脉冲来控制其余的过渡。特别是，我们研究了拉比振荡对射频脉冲频率和强度的依赖性。我们的结果为NV中心的新型控制铺平了道路，以实现量子信息处理和量子传感。
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.
