New quantum sensor detects gravitational waves; fiber micro-tweezers offer precise manipulation

Researchers have developed a novel quantum sensor capable of detecting faint signals, potentially aiding in the search for gravitational waves and dark matter. This new sensor effectively cancels out background noise that previously interfered with measurements. Separately, a team from Anhui University and the University of Science and Technology of China has created a 3D fiber micro-tweezers using femtosecond laser manufacturing, enabling precise manipulation of micro-scale objects with significantly higher force than traditional optical tweezers.

    New Quantum Sensors 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)
