Creating high flux degenerate quantum atomic sources with active feedback

该项目旨在提供一种冷却稀超冷气体的新技术，这些气体正迅速从基础物理平台过渡到量子技术的构建模块。这种技术是基于测量的反馈冷却。与目前的蒸发方法不同，反馈冷却既不损失原子，也不依赖于弹性碰撞或内部原子结构。这开辟了直接冷却传统上不可冷却系统的可能性。该项目将扩大可用原子源的质量和范围，有利于外来材料的研究，并提高精密传感器的应用。量子传感器正在迅速改变我们对传感器是什么以及它能做什么的印象，为传感器融合提供了前所未有的机会，并直接影响到矿产勘探、测绘和导航方面的商机。

This project aims to deliver a new technique for cooling dilute ultracold gases, which are rapidly transitioning from a fundamental physics platform to a building block for quantum technology. This technique is measurement-based feedback cooling. Unlike the current evaporative methods, feedback cooling neither loses atoms, nor relies on elastic collisions or internal atomic structure. This opens up the possibility of directly cooling traditionally un-coolable systems. This project will expand the quality and range of available atomic sources, benefitting research into exotic materials, and improving precision sensor applications. Quantum sensors are rapidly reforming our image of what a sensor is and what it can do, offering unprecedented opportunities in sensor fusion, and directly impacting business opportunities in mineral exploration, mapping and navigation.
