Nitrogen-vacancy (NV) centers in diamond have become an important instrument for quantum sensing and quantum information science. However, the readout of NV spin state requires bulky optical setups, limiting fabrication of miniaturized compact devices for practical use. Here we realized photoelectrical detection of magnetic resonance as well as Rabi oscillations on a single-defect level. Furthermore, photoelectrical imaging of individual NV centers at room temperature was demonstrated, surpassing conventional optical readout methods by providing high imaging contrast and signal-to-noise ratio. These results pave the way toward fully integrated quantum diamond devices.
金刚石中的氮空位（NV）中心已成为量子传感和量子信息科学的重要工具。然而，NV自旋态的读出需要庞大的光学装置，这限制了实际应用中微型紧凑设备的制造。在此，我们实现了单缺陷水平上磁共振以及拉比振荡的光电检测。此外，还展示了室温下单个NV中心的光电成像，通过提供高成像对比度和信噪比超越了传统光学读出方法。这些结果为全集成量子金刚石器件铺平了道路。
