New Quantum Sensor Developed in UK Can Detect Gravitational Waves and Dark Matter
英国《自然》杂志日前发布的一项新研究结果显示，一种新型量子传感器能有效消除背景噪声对测量精度的影响，可用于搜寻此前技术难以探测的微弱信号，有助于解开超大质量黑洞形成之谜。牵头这项研究的英国帝国理工学院发布新闻公报表示，了解宇宙的组成成分以及发现新的引力波源需要测量极微弱的信号。原子干涉仪利用原子物质波的干涉进行测量，但测量所需使用的激光脉冲本身具有噪声，可能会淹没信号，导致无法获得有意义的数据。 (新华社)
Researchers at Imperial College London have developed a novel quantum sensor capable of significantly reducing background noise, enhancing the precision of measurements. This breakthrough technology is expected to aid in the search for faint signals previously undetectable by existing methods. Such signals are crucial for understanding the composition of the universe and identifying new sources of gravitational waves. The sensor utilizes atomic interferometry, which relies on the interference of atomic matter waves. A key challenge addressed by this new sensor is the inherent noise from the lasers used in atomic interferometers, which can obscure weak signals. This advancement holds promise for unlocking mysteries surrounding the formation of supermassive black holes.
This development could lead to significant advancements in our understanding of fundamental physics and cosmology.
