论文摘要
我们使用钻石中的氮胶菌（NV）中心作为量子传感器的电子自旋报告了单个质子核自旋的检测和相干控制。除了通过使用多个序列来确定NV-Proton超细参数外，我们还旋转单质子自旋并相干地旋转，并检测诱导的自由进动。观察自由诱导衰变是高分辨率质子核磁共振的重要成分，并且目前的工作将其扩展到原子尺度。我们还讨论了质子作为化学蒸气沉积生长过程中质子的起源，该质子为钻石中的质子作为内置量子记忆和NV中心提供了机会。
We report detection and coherent control of a single proton nuclear spin using an electronic spin of the nitrogen-vacancy (NV) center in diamond as a quantum sensor. In addition to determining the NV-proton hyperfine parameters by employing multipulse sequences, we polarize and coherently rotate the single proton spin, and detect an induced free precession. Observation of free induction decays is an essential ingredient for high resolution proton nuclear magnetic resonance, and the present work extends it to the atomic scale. We also discuss the origin of the proton as incorporation during chemical vapor deposition growth, which provides an opportunity to use protons in diamond as built-in quantum memories coupled with the NV center.
