Performing cold microwave measurements with warm diamonds

在室温下检测微弱的微波信号是一项非常困难的任务，因为我们周围存在过多的热微波噪声。目前，最好的微波接收器必须冷却到低温，限制了它们的广泛使用。该项目旨在应用基于金刚石的量子技术，在室温设置下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检测器。测量弱微波信号的能力对一系列部门至关重要，该项目的成果预计将应用于国防（雷达）、空间探索（卫星通信）和基础研究（光谱学）。

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).
