摘要:

金刚石中的氮空位(NV)心是一种很有前途的量子信息处理和量子传感系统,而对它的量子态的控制是其实际应用的基础。在这项研究中,我们证明了所有的三个之间的基态子能级的NV中心通过施加外部磁场驱动场的控制。为了解决四个轴中的特定NV轴的状态,我们施加正交于NV轴的磁场。我们用微波脉冲控制两个跃迁,用射频脉冲控制其余跃迁。特别是,我们调查拉比振荡的频率和强度的射频脉冲的依赖性。我们的结果为实现量子信息处理和量子传感提供了一种新的NV中心控制方法。

英文摘要:

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.
