论文摘要
射频（RF）技术的快速发展增加了对紧凑，低消耗和实时RF光谱分析仪的需求。为了克服电子溶液所遇到的电子瓶颈，将实时带宽限制为数百个MHz，我们提出了一种新方法，利用了钻石中氮胶合（NV）中心的量子特性。在这里，我们描述了量子钻石信号分析仪（Q-DISA）平台，并表征其性能。我们成功地检测了大型可调频率范围（25 GHz），宽瞬时带宽（最大4 GHz），MHz频率分辨率（下降到1 MHz），MS时间分辨率和较大的动态范围（40 dB）的RF信号。
The fast development of radio-frequency (RF) technologies increases the need for compact, low consumption and broadband real-time RF spectral analyser. To overcome the electronic bottleneck encountered by electronic solutions, which limits the real time bandwidth to hundreds of MHz, we propose a new approach exploiting the quantum properties of the nitrogen-vacancy (NV) center in diamond. Here we describe a Quantum Diamond Signal Analyser (Q-DiSA) platform and characterize its performances. We successfully detect RF signals over a large tunable frequency range (25 GHz), a wide instantaneous bandwidth (up to 4 GHz), a MHz frequency resolution (down to 1 MHz), a ms temporal resolution and a large dynamic range (40 dB).
