A rotation sensor is one of the key elements of inertial navigation systems and compliments most cell phone sensor sets used for various applications. Currently, inexpensive and efficient solutions are mechanoelectronic devices, which nevertheless lack long-term stability. Realization of rotation sensors based on spins of fundamental particles may become a drift-free alternative to such devices. Here, we carry out a proof-of-concept experiment, demonstrating rotation measurements on a rotating setup utilizing nuclear spins of an ensemble of nitrogen vacancy centers as a sensing element with no stationary reference. The measurement is verified by a commercially available microelectromechanical system gyroscope.
旋转传感器是惯性导航系统的关键元件之一，可补充用于各种应用的大多数手机传感器组。目前，廉价且高效的解决方案是机电设备，但它们缺乏长期稳定性。基于基本粒子自旋实现的旋转传感器可能成为此类设备的无漂移替代方案。在此，我们进行了一项概念验证实验，展示了在一个旋转装置上进行的旋转测量，该装置利用氮空位中心系综的核自旋作为传感元件，且无需固定参考。该测量由商用微机电系统陀螺仪进行了验证。
