论文摘要
量子传感中NV中心的常规控制策略是基于其三胞胎基态的两级模型。然而，正如我们所证明的那样，这种方法在弱偏置磁场或强微波脉冲方面失败。为了克服这一局限性，我们提出了一个新颖的控制序列，该顺序通过用微波脉冲来调查零视野跃迁的微波脉冲来利用这三个级别。我们报告了在典型的动态脱钩序列中表现出色的表现，从而为低场环境打开了纳米-NMR操作的可能性。
Conventional control strategies for NV centers in quantum sensing are based on a two-level model of their triplet ground state. However, this approach fails in regimes of weak bias magnetic fields or strong microwave pulses, as we demonstrate. To overcome this limitation, we propose a novel control sequence that exploits all three levels by addressing a hidden Raman configuration with microwave pulses tuned to the zero-field transition. We report excellent performance in typical dynamical decoupling sequences, opening up the possibility for nano-NMR operation in low-field environments.
