Detecting weak microwave signals at room temperature is an exceptionally difficult task, due to the excessive thermal microwave noise that exists all around us. At present, the best microwave receivers must be cooled to cryogenic temperatures, restricting their widespread use. This project aims to apply diamond-based quantum technologies to achieve unprecedented microwave signal detection sensitivities with a room-temperature setup, providing more accessible ultra-low noise detectors. The ability to measure weak microwave signals is crucial for a range of sectors and the results of this project are expected to have applications in defence (radar), space exploration (satellite communication), and fundamental research (spectroscopy).

由于我们周围存在着过多的热微波噪声，因此在室温下检测微弱的微波信号是一项异常困难的任务。目前，最好的微波接收器必须冷却到低温，限制了其广泛使用。该项目旨在应用基于钻石的量子技术，通过室温设置实现前所未有的微波信号检测灵敏度，提供更容易获得的超低噪声探测器。测量微弱微波信号的能力对一系列部门至关重要，预计该项目的成果将在国防(雷达)、空间探索(卫星通信)和基础研究(光谱学)中得到应用。
